dmaengine: at_xdmac: fix AT_XDMAC_CC_PERID() macro

[ Upstream commit 320c88a3104dc955f928a1eecebd551ff89530c0 ]

AT_XDMAC_CC_PERID() should be used to setup bits 24..30 of XDMAC_CC
register. Using it without parenthesis around 0x7f & (i) will lead to
setting all the time zero for bits 24..30 of XDMAC_CC as the << operator
has higher precedence over bitwise &. Thus, add paranthesis around
0x7f & (i).

PCI: uniphier: Serialize INTx masking/unmasking and fix the bit operation

[ Upstream commit 4caab28a6215da5f3c1b505ff08810bc6acfe365 ]

The condition register PCI_RCV_INTX is used in irq_mask() and irq_unmask()
callbacks. Accesses to register can occur at the same time without a lock.
Add a lock into each callback to prevent the issue.

And INTX mask and unmask fields in PCL_RCV_INTX register should only be
set/reset for each bit. Clearing by PCL_RCV_INTX_ALL_MASK should be
removed.

INTX status fields in PCL_RCV_INTX register only indicates each INTX
interrupt status, so the handler can't clear by writing 1 to the field.
The status is expected to be cleared by the interrupt origin.
The ack function has no meaning, so should remove it.

using CRSSVE flag for handling CRS responses.

PCI_EXP_RTCTL_CRSSVE flag is stored only in emulated config space buffer
and there is handler for PCI_EXP_RTCTL register. So every read operation
from config space automatically clears CRSSVE flag as it is not defined in

appending it to PCI_EXP_RTCTL read response.

mips_cm_error_report() extracts the cause and other cause from the error
register using shifts.  This works fine for the former, as it is stored
in the top bits, and the shift will thus remove all non-related bits.
However, the latter is stored in the bottom bits, hence thus needs masking
to get rid of non-related bits.  Without such masking, using it as an
index into the cm2_causes[] array will lead to an out-of-bounds access,
probably causing a crash.

Fix this by using FIELD_GET() instead.  Bite the bullet and convert all

ASoC: cs42l42: Correct configuring of switch inversion from ts-inv

[ Upstream commit 778a0cbef5fb76bf506f84938517bb77e7a1c478 ]

The setting from the cirrus,ts-inv property should be applied to the
TIP_SENSE_INV bit, as this is the one that actually affects the jack
detect block. The TS_INV bit only swaps the meaning of the PLUG and
UNPLUG interrupts and should always be 1 for the interrupts to have
the normal meaning.

Due to some misunderstanding the driver had been implemented to
configure the TS_INV bit based on the jack switch polarity. This made
the interrupts behave the correct way around, but left the jack detect
block, button detect and analogue circuits always interpreting an open
switch as unplugged.

The signal chain inside the codec is:

SENSE pin -> TIP_SENSE_INV -> TS_INV -> (invert) -> interrupts
                  |
                  v
             Jack detect,
          button detect and
            analog control

As the TIP_SENSE_INV already performs the necessary inversion the
TS_INV bit never needs to change. It must always be 1 to yield the
expected interrupt behaviour.

Some extra confusion has arisen because of the additional invert in the
interrupt path, meaning that a value applied to the TS_INV bit produces
the opposite effect of applying it to the TIP_SENSE_INV bit. The ts-inv
property has therefore always had the opposite effect to what might be
expected (0 = inverted, 1 = not inverted). To maintain the meaning of
the ts-inv property it must be inverted when applied to TIP_SENSE_INV.

HID: u2fzero: properly handle timeouts in usb_submit_urb

The wait_for_completion_timeout function returns 0 if timed out or a
positive value if completed. Hence, "less than zero" comparison always
misses timeouts and doesn't kill the URB as it should, leading to
re-sending it while it is active.

HID: u2fzero: clarify error check and length calculations

[ Upstream commit b7abf78b7a6c4a29a6e0ba0bb883fe44a2f3d693 ]

The previous commit fixed handling of incomplete packets but broke error
handling: offsetof returns an unsigned value (size_t), but when compared
against the signed return value, the return value is interpreted as if
it were unsigned, so negative return values are never less than the
offset.

To make the code easier to read, calculate the minimal packet length
once and separately, and assign it to a signed int variable to eliminate
unsigned math and the need for type casts. It then becomes immediately
obvious how the actual data length is calculated and why the return
value cannot be less than the minimal length.

serial: xilinx_uartps: Fix race condition causing stuck TX

[ Upstream commit 88b20f84f0fe47409342669caf3e58a3fc64c316 ]

xilinx_uartps .start_tx() clears TXEMPTY when enabling TXEMPTY to avoid
any previous TXEVENT event asserting the UART interrupt. This clear
operation is done immediately after filling the TX FIFO.

However, if the bytes inserted by cdns_uart_handle_tx() are consumed by
the UART before the TXEMPTY is cleared, the clear operation eats the new
TXEMPTY event as well, causing cdns_uart_isr() to never receive the
TXEMPTY event. If there are bytes still queued in circbuf, TX will get
stuck as they will never get transferred to FIFO (unless new bytes are
queued to circbuf in which case .start_tx() is called again).

While the racy missed TXEMPTY occurs fairly often with short data
sequences (e.g. write 1 byte), in those cases circbuf is usually empty
so no action on TXEMPTY would have been needed anyway. On the other
hand, longer data sequences make the race much more unlikely as UART
takes longer to consume the TX FIFO. Therefore it is rare for this race
to cause visible issues in general.

Fix the race by clearing the TXEMPTY bit in ISR *before* filling the
FIFO.

The TXEMPTY bit in ISR will only get asserted at the exact moment the
TX FIFO *becomes* empty, so clearing the bit before filling FIFO does
not cause an extra immediate assertion even if the FIFO is initially
empty.

This is hard to reproduce directly on a normal system, but inserting
e.g. udelay(200) after cdns_uart_handle_tx(port), setting 4000000 baud,
and then running "dd if=/dev/zero bs=128 of=/dev/ttyPS0 count=50"
reliably reproduces the issue on my ZynqMP test system unless this fix
is applied.

scsi: ufs: ufshcd-pltfrm: Fix memory leak due to probe defer

[ Upstream commit b6ca770ae7f2c560a29bbd02c4e3d734fafaf804 ]

UFS drivers that probe defer will end up leaking memory allocated for clk
and regulator names via kstrdup() because the structure that is holding
this memory is allocated via devm_* variants which will be freed during
probe defer but the names are never freed.

Use same devm_* variant of kstrdup to free the memory allocated to name
when driver probe defers.

iio: adis: do not disabe IRQs in 'adis_init()'

[ Upstream commit b600bd7eb333554518b4dd36b882b2ae58a5149e ]

With commit ecb010d441088 ("iio: imu: adis: Refactor adis_initial_startup")
we are doing a HW or SW reset to the device which means that we'll get
the default state of the data ready pin (which is enabled). Hence there's
no point in disabling the IRQ in the init function. Moreover, this
function is intended to initialize internal data structures and not
really do anything on the device.

As a result of this, some devices were left with the data ready pin enabled
after probe which was not the desired behavior. Thus, we move the call to
'adis_enable_irq()' to the initial startup function where it makes more
sense for it to be.

Note that for devices that cannot mask/unmask the pin, it makes no sense
to call the function at this point since the IRQ should not have been
yet requested. This will be improved in a follow up change.

should not "depend on" it. They should depend on I2C and then

soc: qcom: rpmhpd: Make power_on actually enable the domain

[ Upstream commit e3e56c050ab6e3f1bd811f0787f50709017543e4 ]

The general expectation is that powering on a power-domain should make
the power domain deliver some power, and if a specific performance state
is needed further requests has to be made.

But in contrast with other power-domain implementations (e.g. rpmpd) the
RPMh does not have an interface to enable the power, so the driver has
to vote for a particular corner (performance level) in rpmh_power_on().

But the corner is never initialized, so a typical request to simply
enable the power domain would not actually turn on the hardware. Further
more, when no more clients vote for a performance state (i.e. the
aggregated vote is 0) the power domain would be turned off.

Fix both of these issues by always voting for a corner with non-zero
value, when the power domain is enabled.

The tracking of the lowest non-zero corner is performed to handle the
corner case if there's ever a domain with a non-zero lowest corner, in
which case both rpmh_power_on() and rpmh_rpmhpd_set_performance_state()
would be allowed to use this lowest corner.

ARM: dts: stm32: Reduce DHCOR SPI NOR frequency to 50 MHz

[ Upstream commit 2012579b31293d0a8cf2024e9dab66810bf1a15e ]

The SPI NOR is a bit further away from the SoC on DHCOR than on DHCOM,
which causes additional signal delay. At 108 MHz, this delay triggers
a sporadic issue where the first bit of RX data is not received by the
QSPI controller.

There are two options of addressing this problem, either by using the
DLYB block to compensate the extra delay, or by reducing the QSPI bus
clock frequency. The former requires calibration and that is overly
complex, so opt for the second option.

staging: most: dim2: do not double-register the same device

[ Upstream commit 2ab189164056b05474275bb40caa038a37713061 ]

Commit 723de0f9171e ("staging: most: remove device from interface
structure") moved registration of driver-provided struct device to
the most subsystem.

Dim2 used to register the same struct device to provide a custom device
attribute. This causes double-registration of the same struct device.

Fix that by moving the custom attribute to driver's dev_groups.
This moves attribute to the platform_device object, which is a better
location for platform-specific attributes anyway.

powerpc: Fix is_kvm_guest() / kvm_para_available()

[ Upstream commit 95839225639ba7c3d8d7231b542728dcf222bf2d ]

Commit a21d1becaa3f ("powerpc: Reintroduce is_kvm_guest() as a fast-path
check") added is_kvm_guest() and changed kvm_para_available() to use it.

is_kvm_guest() checks a static key, kvm_guest, and that static key is
set in check_kvm_guest().

The problem is check_kvm_guest() is only called on pseries, and even
then only in some configurations. That means is_kvm_guest() always
returns false on all non-pseries and some pseries depending on
configuration. That's a bug.

For PR KVM guests this is noticable because they no longer do live
patching of themselves, which can be detected by the omission of a
message in dmesg such as:

  KVM: Live patching for a fast VM worked

To fix it make check_kvm_guest() an initcall, to ensure it's always
called at boot. It needs to be core so that it runs before
kvm_guest_init() which is postcore. To be an initcall it needs to return
int, where 0 means success, so update that.

We still call it manually in pSeries_smp_probe(), because that runs
before init calls are run.

This is due to 'dcbz' instruction being used on non-cached memory.
'dcbz' instruction is used by memset() to zeroize a complete
cacheline at once, and memset() is not expected to be used on non
cached memory.

When performing a 'sparse' check on fbdev driver, it also appears
that the use of memset() is unexpected:

  drivers/video/fbdev/chipsfb.c:334:17: warning: incorrect type in argument 1 (different address spaces)

ALSA: hda: Release controller display power during shutdown/reboot

[ Upstream commit 472e18f63c425dda97b888f40f858ea54e3efc17 ]

Make sure the HDA driver's display power reference is released during
shutdown/reboot.

During the shutdown/reboot sequence the pci device core calls the
pm_runtime_resume handler for all devices before calling the driver's
shutdown callback and so the HDA driver's runtime resume callback will
acquire a display power reference (on HSW/BDW). This triggers a power
reference held WARN on HSW/BDW in the i915 driver's subsequent shutdown
handler, which expects all display power references to be released by
that time.

Since the HDA controller is stopped in the shutdown handler in any case,
let's follow here the same sequence as the one during runtime suspend.
This will also reset the HDA link and drop the display power reference,
getting rid of the above WARN.

Tested on HSW.

ALSA: hda: Reduce udelay() at SKL+ position reporting

[ Upstream commit 46243b85b0ec5d2cee7545e5ce18c015ce91957e ]

The position reporting on Intel Skylake and later chips via
azx_get_pos_skl() contains a udelay(20) call for the capture streams.
A call for this alone doesn't sound too harmful.  However, as the
pointer PCM ops is one of the hottest path in the PCM operations --
especially for the timer-scheduled operations like PulseAudio -- such
a delay hogs CPU usage significantly in the total performance.

The code there was taken from the original code in ASoC SST Skylake
driver blindly.  The udelay() is a workaround for the case where the
reported position is behind the period boundary at the timing
triggered from interrupts; applications often expect that the full
data is available for the whole period when returned (and also that's
the definition of the ALSA PCM period).

OTOH, HD-audio (legacy) driver has already some workarounds for the
delayed position reporting due to its relatively large FIFO, such as
the BDL position adjustment and the delayed period-elapsed call in the
work.  That said, the udelay() is almost superfluous for HD-audio
driver unlike SST, and we can drop the udelay().

Though, the current code doesn't guarantee the full period readiness
as mentioned in the above, but rather it checks the wallclock and
detects the unexpected jump.  That's one missing piece, and the drop
of udelay() needs a bit more sanity checks for the delayed handling.

This patch implements those: the drop of udelay() call in
azx_get_pos_skl() and the more proper check of hwptr in
azx_position_ok().  The latter change is applied only for the case
where the stream is running in the normal mode without
no_period_wakeup flag.  When no_period_wakeup is set, it essentially
ignores the period handling and rather concentrates only on the
current position; which implies that we don't need to care about the
period boundary at all.

arm64: dts: qcom: pm8916: Remove wrong reg-names for rtc@6000

[ Upstream commit 483de2b44cd3a168458f8f9ff237e78a434729bc ]

While removing the size from the "reg" properties in pm8916.dtsi,
commit bd6429e81010 ("ARM64: dts: qcom: Remove size elements from

address for the rtc@6000 device. That one did not represent the size
of the register region but actually the address of the second "alarm"
register region of the rtc@6000 device.

Now there are "reg-names" for two "reg" elements, but there is actually
only one "reg" listed.

Since the DT schema for "qcom,pm8941-rtc" only expects one "reg"
element anyway, just drop the "reg-names" entirely to fix this.

arm64: dts: qcom: msm8916: Fix Secondary MI2S bit clock

[ Upstream commit 8199a0b31e76d158ac14841e7119890461f8c595 ]

At the moment, playing audio on Secondary MI2S will just end up getting
stuck, without actually playing any audio. This happens because the wrong
bit clock is configured when playing audio on Secondary MI2S.

The PRI_I2S_CLK (better name: SPKR_I2S_CLK) is used by the SPKR audio mux
block that provides both Primary and Secondary MI2S.

The SEC_I2S_CLK (better name: MIC_I2S_CLK) is used by the MIC audio mux
block that provides Tertiary MI2S. Quaternary MI2S is also part of the
MIC audio mux but has its own clock (AUX_I2S_CLK).

This means that (quite confusingly) the SEC_I2S_CLK is not actually
used for Secondary MI2S as the name would suggest. Secondary MI2S
needs to have the same clock as Primary MI2S configured.

Fix the clock list for the lpass node in the device tree and add
a comment to clarify this confusing naming. With these changes,
audio can be played correctly on Secondary MI2S.

[ Upstream commit b3e9431854e8f305385d5de225441c0477b936cb ]

On resume we can get a warning at kernel/time/timekeeping.c:824 for
timekeeping_suspended.

Let's fix this by adding separate functions for sysc_poll_reset_sysstatus()
and sysc_poll_reset_sysconfig() and have the new functions handle also
timekeeping_suspended.

If iopoll at some point supports timekeeping_suspended, we can just drop
the custom handling from these functions.

iio: st_sensors: disable regulators after device unregistration

[ Upstream commit 9f0b3e0cc0c88618aa9e5cecef747b1337ae0a5d ]

Up until commit ea7e586bdd331 ("iio: st_sensors: move regulator retrieveal
to core") only the ST pressure driver seems to have had any regulator
disable. After that commit, the regulator handling was moved into the
common st_sensors logic.

In all instances of this regulator handling, the regulators were disabled
before unregistering the IIO device.
This can cause issues where the device would be powered down and still be
available to userspace, allowing it to send invalid/garbage data.

This change moves the st_sensors_power_disable() after the common probe
functions. These common probe functions also handle unregistering the IIO
device.
