ovl: update of dentry revalidate flags after copy up

[ Upstream commit b07d5cc93e1b28df47a72c519d09d0a836043613 ]

After copy up, we may need to update d_flags if upper dentry is on a
remote fs and lower dentries are not.

Add helpers to allow incremental update of the revalidate flags.

drm/amdgpu: Fix usage of UMC fill record in RAS

[ Upstream commit 71344a718a9fda8c551cdc4381d354f9a9907f6f ]

The fixed commit listed in the Fixes tag below, introduced a bug in
amdgpu_ras.c::amdgpu_reserve_page_direct(), in that when introducing the new
amdgpu_umc_fill_error_record() and internally in that new function the physical
address (argument "uint64_t retired_page"--wrong name) is right-shifted by
AMDGPU_GPU_PAGE_SHIFT. Thus, in amdgpu_reserve_page_direct() when we pass
"address" to that new function, we should NOT right-shift it, since this
results, erroneously, in the page address to be 0 for first
2^(2*AMDGPU_GPU_PAGE_SHIFT) memory addresses.

This commit fixes this bug.

[ Upstream commit a4366b5695c984b8a3fc8b31de9e758c8f6d1aed ]

The capacity-dmips-mhz parameter was miscalculated: this SoC runs
the first (Cortex-A55) cluster at a maximum of 2000MHz and the
second (Cortex-A76) cluster at a maximum of 2200MHz.

In order to calculate the right capacity-dmips-mhz, the following
test was performed:
1. CPUFREQ governor was set to 'performance' on both clusters
2. Ran dhrystone with 500000000 iterations for 10 times on each cluster
3. Calculated the mean result for each cluster
4. Calculated DMIPS/MHz: dmips_mhz = dmips_per_second / cpu_mhz
5. Scaled results to 1024:
   result_c0 = dmips_mhz_c0 / dmips_mhz_c1 * 1024

The mean results for this SoC are:
Cluster 0 (LITTLE): 12016411 Dhry/s
Cluster 1 (BIG): 31702034 Dhry/s

The calculated scaled results are:
Cluster 0: 426.953226899238 (rounded to 427)
Cluster 1: 1024

drm/msm/dsi: Remove incorrect references to slice_count

[ Upstream commit 155fa3a91d64221eb0885fd221cc8085dbef908f ]

Currently, slice_count is being used to calculate word count and
pkt_per_line. Instead, these values should be calculated using slice per
packet, which is not the same as slice_count.

Slice count represents the number of slices per interface, and its value
will not always match that of slice per packet. For example, it is possible
to have cases where there are multiple slices per interface but the panel
specifies only one slice per packet.

Thus, use the default value of one slice per packet and remove slice_count
from the aforementioned calculations.

should be the other way around.  In other words, when the panel driver
requests to use more slices per packet than what could be sent over this

drm/msm/dsi: Use DSC slice(s) packet size to compute word count

[ Upstream commit bc6b6ff8135c4b96787eda88f3baf653939a75ce ]

According to downstream the value to use for WORD_COUNT is
bytes_per_pkt, which denotes the number of bytes in a packet based on
how many slices have been configured by the panel driver times the
width of a slice times the number of bytes per pixel.

The DSC panels seen thus far use one byte per pixel, only one slice
per packet, and a slice width of half the panel width leading to the
desired bytes_per_pkt+1 value to be equal to hdisplay/2+1.  This however
isn't the case anymore for panels that configure two slices per packet,
where the value should now be hdisplay+1.

Note that the aforementioned panel (on a Sony Xperia XZ3, sdm845) with
slice_count=1 has also been tested to successfully accept slice_count=2,
which would have shown corrupted output previously.

RDMA/bnxt_re: wraparound mbox producer index

Driver is not handling the wraparound of the mbox producer index correctly.
Currently the wraparound happens once u32 max is reached.

Bit 31 of the producer index register is special and should be set
only once for the first command. Because the producer index overflow
setting bit31 after a long time, FW goes to initialization sequence
and this causes FW hang.

[ Upstream commit b18f05a0666aecd5cb19c26a8305bcfa4e9d6502 ]

[Why]
When freesync video mode is enabled, switching resolution from native
mode to one of the freesync video compatible modes can trigger continous
artifacts on some eDP panels when running under KDE. The articating can be seen in the
attached bug report.

[How]
Fix this by restricting updates that require full commit by using the same checks
for stream and scaling changes in the the enable pass of dm_update_crtc_state()
along with the check for compatible timings for freesync vide mode.

hwmon: (pmbus/adm1275) Fix problems with temperature monitoring on ADM1272

[ Upstream commit b153a0bb4199566abd337119207f82b59a8cd1ca ]

The PMON_CONFIG register on ADM1272 is a 16 bit register. Writing a 8 bit
value into it clears the upper 8 bits of the register, resulting in
unexpected side effects. Fix by writing the 16 bit register value.

Also, it has been reported that temperature readings are sometimes widely
inaccurate, to the point where readings may result in device shutdown due
to errant overtemperature faults. Improve by enabling temperature sampling.

While at it, move the common code for ADM1272 and ADM1278 into a separate
function, and clarify in the error message that an attempt was made to
enable both VOUT and temperature monitoring.

Last but not least, return the error code reported by the underlying I2C
controller and not -ENODEV if updating the PMON_CONFIG register fails.
After all, this does not indicate that the chip is not present, but an
error in the communication with the chip.

IB/hfi1: Fix wrong mmu_node used for user SDMA packet after invalidate

[ Upstream commit c9358de193ecfb360c3ce75f27ce839ca0b0bc8c ]

The hfi1 user SDMA pinned-page cache will leave a stale cache entry when
the cache-entry's virtual address range is invalidated but that cache
entry is in-use by an outstanding SDMA request.

Subsequent user SDMA requests with buffers in or spanning the virtual
address range of the stale cache entry will result in packets constructed
from the wrong memory, the physical pages pointed to by the stale cache
entry.

To fix this, remove mmu_rb_node cache entries from the mmu_rb_handler
cache independent of the cache entry's refcount. Add 'struct kref
refcount' to struct mmu_rb_node and manage mmu_rb_node lifetime with
kref_get() and kref_put().

mmu_rb_node.refcount makes sdma_mmu_node.refcount redundant. Remove
'atomic_t refcount' from struct sdma_mmu_node and change sdma_mmu_node
code to use mmu_rb_node.refcount.

Move the mmu_rb_handler destructor call after a
wait-for-SDMA-request-completion call so mmu_rb_nodes that need
mmu_rb_handler's workqueue to queue themselves up for destruction from an
interrupt context may do so.

Fix build errors in soc/fsl/qe/usb.c when QUICC_ENGINE is not set.
This happens when PPC_EP88XC is set, which selects CPM1 & CPM.
When CPM is set, USB_FSL_QE can be set without QUICC_ENGINE
being set. When USB_FSL_QE is set, QE_USB deafults to y, which
causes build errors when QUICC_ENGINE is not set. Making
QE_USB depend on QUICC_ENGINE prevents QE_USB from defaulting to y.

Fixes these build errors:

ARM: dts: meson8: correct uart_B and uart_C clock references

[ Upstream commit 98b503c7fb13a17a47d8ebf15fa8f7c10118e75c ]

On Meson8 uart_B and uart_C do not work, because they are relying on
incorrect clocks. Change the references of pclk to the correct CLKID
(UART1 for uart_B and UART2 for uart_C), to allow use of the two uarts.

This was originally reported by Hans-Frieder Vogt for Meson8b [0], but
the same bug is also present in meson8.dtsi

ASoC: es8316: Do not set rate constraints for unsupported MCLKs

[ Upstream commit 60413129ee2b38a80347489270af7f6e1c1de4d0 ]

When using the codec through the generic audio graph card, there are at
least two calls of es8316_set_dai_sysclk(), with the effect of limiting
the allowed sample rates according to the MCLK/LRCK ratios supported by
the codec:

1. During audio card setup, to set the initial MCLK - see
   asoc_simple_init_dai().

2. Before opening a stream, to update MCLK, according to the stream
   sample rate and the multiplication factor - see
   asoc_simple_hw_params().

In some cases the initial MCLK might be set to a frequency that doesn't
match any of the supported ratios, e.g. 12287999 instead of 12288000,
which is only 1 Hz below the supported clock, as that is what the
hardware reports. This creates an empty list of rate constraints, which
is further passed to snd_pcm_hw_constraint_list() via
es8316_pcm_startup(), and causes the following error on the very first
access of the sound card:

  $ speaker-test -D hw:Analog,0 -F S16_LE -c 2 -t wav
  Broken configuration for playback: no configurations available: Invalid argument
  Setting of hwparams failed: Invalid argument

Note that all subsequent retries succeed thanks to the updated MCLK set
at point 2 above, which uses a computed frequency value instead of a
reading from the hardware registers. Normally this would have mitigated
the issue, but es8316_pcm_startup() executes before the 2nd call to
es8316_set_dai_sysclk(), hence it cannot make use of the updated
constraints.

Since es8316_pcm_hw_params() performs anyway a final validation of MCLK
against the stream sample rate and the supported MCLK/LRCK ratios, fix
the issue by ensuring that sysclk_constraints list is only set when at
least one supported sample rate is autodetected by the codec.

ASoC: es8316: Increment max value for ALC Capture Target Volume control

[ Upstream commit 6f073429037cd79d7311cd8236311c53f5ea8f01 ]

The following error occurs when trying to restore a previously saved
ALSA mixer state (tested on a Rock 5B board):

  $ alsactl --no-ucm -f /tmp/asound.state store hw:Analog
  $ alsactl --no-ucm -I -f /tmp/asound.state restore hw:Analog
  alsactl: set_control:1475: Cannot write control '2:0:0:ALC Capture Target Volume:0' : Invalid argument

According to ES8316 datasheet, the register at address 0x2B, which is
related to the above mixer control, contains by default the value 0xB0.
Considering the corresponding ALC target bits (ALCLVL) are 7:4, the
control is initialized with 11, which is one step above the maximum
value allowed by the driver:

 ALCLVL | dB gain
 -------+--------
  0000  |  -16.5
  0001  |  -15.0
  0010  |  -13.5
  ....  |  .....
  0111  |   -6.0
  1000  |   -4.5
  1001  |   -3.0
  1010  |   -1.5
  ....  |  .....
  1111  |   -1.5

The tests performed using the VU meter feature (--vumeter=TYPE) of
arecord/aplay confirm the specs are correct and there is no measured
gain if the 1011-1111 range would have been mapped to 0 dB:

 dB gain | VU meter %
 --------+-----------
   -6.0  |  30-31
   -4.5  |  35-36
   -3.0  |  42-43
   -1.5  |  50-51
    0.0  |  50-51

Increment the max value allowed for ALC Capture Target Volume control,
so that it matches the hardware default.  Additionally, update the
related TLV to prevent an artificial extension of the dB gain range.

drm/bridge: ti-sn65dsi83: Fix enable/disable flow to meet spec

[ Upstream commit dd9e329af7236e34c566d3705ea32a63069b9b13 ]

The datasheet describes the following initialization flow including
minimum delay times between each step:

1. DSI data lanes need to be in LP-11 and the clock lane in HS mode
2. toggle EN signal
3. initialize registers
4. enable PLL
5. soft reset
6. enable DSI stream
7. check error status register

To meet this requirement we need to make sure the host bridge's
pre_enable() is called first by using the pre_enable_prev_first
flag.

Furthermore we need to split enable() into pre_enable() which covers
steps 2-5 from above and enable() which covers step 7 and is called
after the host bridge's enable().

drm/bridge: Introduce pre_enable_prev_first to alter bridge init order

[ Upstream commit 4fb912e5e19075874379cfcf074d90bd51ebf8ea ]

DSI sink devices typically want the DSI host powered up and configured
before they are powered up. pre_enable is the place this would normally
happen, but they are called in reverse order from panel/connector towards
the encoder, which is the "wrong" order.

Add a new flag pre_enable_prev_first that any bridge can set
to swap the order of pre_enable (and post_disable) for that and the
immediately previous bridge.
Should the immediately previous bridge also set the
pre_enable_prev_first flag, the previous bridge to that will be called
before either of those which requested pre_enable_prev_first.

eg:
- Panel
- Bridge 1
- Bridge 2 pre_enable_prev_first
- Bridge 3
- Bridge 4 pre_enable_prev_first
- Bridge 5 pre_enable_prev_first
- Bridge 6
- Encoder
Would result in pre_enable's being called as Panel, Bridge 1, Bridge 3,
Bridge 2, Bridge 6, Bridge 5, Bridge 4, Encoder.

arm64: dts: qcom: apq8016-sbc: Fix 1.8V power rail on LS expansion

[ Upstream commit 5500f823db38db073d30557af159b77fb1f2bf26 ]

The 96Boards specification expects a 1.8V power rail on the low-speed
expansion connector that is able to provide at least 0.18W / 100 mA.
According to the DB410c hardware user manual this is done by connecting
both L15 and L16 in parallel with up to 55mA each (for 110 mA total) [1].

Unfortunately the current regulator setup in the DB410c device tree
does not implement the specification correctly and only provides 5 mA:

  - Only L15 is marked always-on, so L16 is never enabled.
  - Without specifying a load the regulator is put into LPM where
    it can only provide 5 mA.

Fix this by:

  - Adding proper voltage constraints for L16.
  - Making L16 always-on.
  - Adding regulator-system-load for both L15 and L16. 100 mA should be
    available in total, so specify 50 mA for each. (The regulator
    hardware can only be in normal (55 mA) or low-power mode (5 mA) so
    this will actually result in the expected 110 mA total...)

arm64: dts: qcom: apq8016-sbc: Fix regulator constraints

[ Upstream commit e27654df20d77ad7549a3cf6739ebaa3aa59a088 ]

For some reason DB410c has completely bogus regulator constraints that
actually just correspond to the programmable voltages which are already
provided by the regulator driver. Some of them are not just outside the
recommended operating conditions of the APQ8016E SoC but even exceed
the absolute maximum ratings, potentially risking permanent device
damage.

In practice it's not quite as dangerous thanks to the RPM firmware:
It turns out that it has its own voltage constraints and silently
clamps all regulator requests. For example, requesting 3.3V for L5
(allowed by the current regulator constraints!) still results in 1.8V
being programmed in the actual regulator hardware.

Experimentation with various voltages shows that the internal RPM
voltage constraints roughly correspond to the safe "specified range"
in the PM8916 Device Specification (rather than the "programmable
range" used inside apq8016-sbc.dtsi right now).

Combine those together with some fixed voltages used in the old
msm-3.10 device tree from Qualcomm to give DB410c some actually valid
voltage constraints.

drm/bridge: anx7625: Prevent endless probe loop

[ Upstream commit 1464e48d69ab7a50a377c9d39f5e5eb3cee2722e ]

During probe, the driver registers i2c dummy devices and populates the
aux bus, which registers a device for the panel. After doing that, the
driver can still defer probe if needed. This ordering of operations is
troublesome however, because the deferred probe work will retry probing
all pending devices every time a new device is registered. Therefore, if
modules need to be loaded in order to satisfy the dependencies for this
driver to complete probe, the kernel will stall, since it'll keep trying
to probe the anx7625 driver, but never succeed, given that modules would
only be loaded after the deferred probe work completes.

Two changes are required to avoid this issue:
* Move of_find_mipi_dsi_host_by_node(), which can defer probe, to before
  anx7625_register_i2c_dummy_clients() and
  devm_of_dp_aux_populate_ep_devices(), which register devices.
* Make use of the done_probing callback when populating the aux bus,
  so that the bridge registration is only done after the panel is
  probed. This is required because the panel might need to defer probe,
  but the aux bus population needs the i2c dummy devices working, so
  this call couldn't just be moved to an earlier point in probe.
  One caveat is that if the panel is described outside the aux bus, the
  probe loop issue can still happen, but we don't have a way to avoid
  it in that case since there's no callback available.

With this patch applied, it's possible to boot on
mt8192-asurada-spherion with

CONFIG_DRM_ANALOGIX_ANX7625=y
CONFIG_MTK_MMSYS=m

RDMA/bnxt_re: Fix to remove an unnecessary log

[ Upstream commit 43774bc156614346fe5dacabc8e8c229167f2536 ]

During destroy_qp, driver sets the qp handle in the existing CQEs
belonging to the QP being destroyed to NULL. As a result, a poll_cq after
destroy_qp can report unnecessary messages.  Remove this noise from system
logs.

The NULL check inside bnxt_re_update_gid() always return false.  If
sgid_tbl->tbl is not allocated, then dev_init would have failed.

RDMA/bnxt_re: Use unique names while registering interrupts

[ Upstream commit ff2e4bfd162cf66a112a81509e419805add44d64 ]

bnxt_re currently uses the names "bnxt_qplib_creq" and "bnxt_qplib_nq-0"
while registering IRQs. There is no way to distinguish the IRQs of
different device ports when there are multiple IB devices registered.
This could make the scenarios worse where one want to pin IRQs of a device
port to certain CPUs.

Fixed the code to use unique names which has PCI BDF information while
registering interrupts like: "bnxt_re-nq-0@pci:0000:65:00.0" and
"bnxt_re-creq@pci:0000:65:00.1".

RDMA/bnxt_re: Disable/kill tasklet only if it is enabled

[ Upstream commit ab112ee7899d6171da5acd77a7ed7ae103f488de ]

When the ulp hook to start the IRQ fails because the rings are not
available, tasklets are not enabled. In this case when the driver is
unloaded, driver calls CREQ tasklet_kill. This causes an indefinite hang
as the tasklet is not enabled.

Driver shouldn't call tasklet_kill if it is not enabled. So using the
creq->requested and nq->requested flags to identify if both tasklets/irqs
are registered. Checking this flag while scheduling the tasklet from
ISR. Also, added a cleanup for disabling tasklet, in case request_irq
fails during start_irq.

Check for return value for bnxt_qplib_rcfw_start_irq and in case the
bnxt_qplib_rcfw_start_irq fails, return bnxt_re_start_irq without
attempting to start NQ IRQs.
