ti_sci_intr_irq_domain_free() assumes that out_irq of intr is stored in

mac80211: don't set set TDLS STA bandwidth wider than possible
[ Upstream commit
f65607cdbc6b0da356ef5a22552ddd9313cf87a0 ]
When we set up a TDLS station, we set sta->sta.bandwidth solely based
on the capabilities, because the "what's the current bandwidth" check
is bypassed and only applied for other types of stations.
This leads to the unfortunate scenario that the sta->sta.bandwidth is
160 MHz if both stations support it, but we never actually configure
this bandwidth unless the AP is already using 160 MHz; even for wider
bandwidth support we only go up to 80 MHz (at least right now.)
For iwlwifi, this can also lead to firmware asserts, telling us that
we've configured the TX rates for a higher bandwidth than is actually
available due to the PHY configuration.
For non-TDLS, we check against the interface's requested bandwidth,
but we explicitly skip this check for TDLS to cope with the wider BW
case. Change this to
(a) still limit to the TDLS peer's own chandef, which gets factored
into the overall PHY configuration we request from the driver,
and
(b) limit it to when the TDLS peer is authorized, because it's only
factored into the channel context in this case.

[ Upstream commit

If generic_drop_inode() returns true, it means iput_final() can evict
this inode regardless of whether it is dirty or not. If we check
I_DONTCACHE in generic_drop_inode(), any inode with this bit set will be
evicted unconditionally. This is not the desired behavior because
I_DONTCACHE only means the inode shouldn't be cached on the LRU list.
As for whether we need to evict this inode, this is what
generic_drop_inode() should do. This patch corrects the usage of
I_DONTCACHE.

wait for complete at the end.
But some random DMA timeout found in this new driver, with the help of
ftrace, we found the root cause is as follows:
Take gpmi_ecc_read_page() as an example, gpmi_nfc_exec_op collected 6
DMA transfers and the DMA chain triggered at the end. It waits for bch
completion and check jiffies if it's timeout. The typical function graph

In the first gpmi_nfc_exec_op, bch_irq comes first and gpmi_nfc_exec_op
exits, but DMA IRQ still not happened yet until the middle of following
gpmi_nfc_exec_op, the first DMA transfer index get messed and DMA get
timeout.
To fix the issue, when there is bch ops in DMA chain, the
gpmi_nfc_exec_op should wait for both completions rather than bch
completion only.

[ Upstream commit

pm_runtime_get_sync() will increment pm usage at first and it
will resume the device later. If runtime of the device has
error or device is in inaccessible state(or other error state),
resume operation will fail. If we do not call put operation to
decrease the reference, it will result in reference leak in
the two functions(gpmi_init and gpmi_nfc_exec_op). Moreover,
this device cannot enter the idle state and always stay busy or
other non-idle state later. So we fixed it through adding
pm_runtime_put_noidle.

50 MHz clock rate for SDC2")). That means then when you run an older

A problem exists in enabling silent stream when connection type is
DisplayPort. Silent stream programming is completed when a new DP
receiver is connected, but infoframe transmission does not actually
start until PCM is opened for the first time. This can result in audible
gap of multiple seconds. This only affects the first PCM open.
Fix the issue by properly assigning a converter to the silent stream,
and modifying the required stream ID programming sequence.

The R-Car V3U clock driver defines the R and OSC clocks using R-Car Gen3

Fix this by introducing clock definition macros specific to R-Car V3U.

[ Upstream commit

There isn't any need to overwrite the mode here in the driver with what
has been detected by the firmware, such as DT or ACPI. In fact, if we
use the SPI CS gpio descriptor feature we will overwrite the mode with
SPI_MODE_0 where it already contains SPI_MODE_0 and more importantly
SPI_CS_HIGH. Clearing the SPI_CS_HIGH bit causes the CS line to toggle
when the device is probed when it shouldn't change, confusing the driver
and making it fail to probe. Drop the assignment and let the spi core
take care of it.

Fix to restore BTF if single-stepping causes a page fault and

Usually the BTF flag was restored when the single stepping is done
(in resume_execution()). However, if a page fault happens on the

the single stepping is cancelled. Thus, the BTF flag is not

NFSD: Fix 5 seconds delay when doing inter server copy
[ Upstream commit
ca9364dde50daba93eff711b4b945fd08beafcc2 ]
Since commit
b4868b44c5628 ("NFSv4: Wait for stateid updates after
CLOSE/OPEN_DOWNGRADE"), every inter server copy operation suffers 5
seconds delay regardless of the size of the copy. The delay is from
nfs_set_open_stateid_locked when the check by nfs_stateid_is_sequential
fails because the seqid in both nfs4_state and nfs4_stateid are 0.
Fix by modifying nfs4_init_cp_state to return the stateid with seqid 1
instead of 0. This is also to conform with section 4.8 of RFC 7862.
Here is the relevant paragraph from section 4.8 of RFC 7862:
A copy offload stateid's seqid MUST NOT be zero. In the context of a
copy offload operation, it is inappropriate to indicate "the most
recent copy offload operation" using a stateid with a seqid of zero
(see Section 8.2.2 of [RFC5661]). It is inappropriate because the
stateid refers to internal state in the server and there may be
several asynchronous COPY operations being performed in parallel on
the same file by the server. Therefore, a copy offload stateid with
a seqid of zero MUST be considered invalid.

pointer. Avoid a null pointer dereference by only emitting the dev_err
message if hdmi_phy is non-null. It is a moot point if the error message

powerpc/pseries/hibernation: drop pseries_suspend_begin() from suspend ops
[ Upstream commit
52719fce3f4c7a8ac9eaa191e8d75a697f9fbcbc ]
There are three ways pseries_suspend_begin() can be reached:
1. When "mem" is written to /sys/power/state:
kobj_attr_store()
-> state_store()
-> pm_suspend()
-> suspend_devices_and_enter()
-> pseries_suspend_begin()
This never works because there is no way to supply a valid stream id
using this interface, and H_VASI_STATE is called with a stream id of
zero. So this call path is useless at best.
2. When a stream id is written to /sys/devices/system/power/hibernate.
pseries_suspend_begin() is polled directly from store_hibernate()
until the stream is in the "Suspending" state (i.e. the platform is
ready for the OS to suspend execution):
dev_attr_store()
-> store_hibernate()
-> pseries_suspend_begin()
3. When a stream id is written to /sys/devices/system/power/hibernate
(continued). After #2, pseries_suspend_begin() is called once again
from the pm core:
dev_attr_store()
-> store_hibernate()
-> pm_suspend()
-> suspend_devices_and_enter()
-> pseries_suspend_begin()
This is redundant because the VASI suspend state is already known to
be Suspending.
The begin() callback of platform_suspend_ops is optional, so we can
simply remove that assignment with no loss of function.

ARM: 9030/1: entry: omit FP emulation for UND exceptions taken in kernel mode
[ Upstream commit
f77ac2e378be9dd61eb88728f0840642f045d9d1 ]
There are a couple of problems with the exception entry code that deals
with FP exceptions (which are reported as UND exceptions) when building
the kernel in Thumb2 mode:
- the conditional branch to vfp_kmode_exception in vfp_support_entry()
may be out of range for its target, depending on how the linker decides
to arrange the sections;
- when the UND exception is taken in kernel mode, the emulation handling
logic is entered via the 'call_fpe' label, which means we end up using
the wrong value/mask pairs to match and detect the NEON opcodes.
Since UND exceptions in kernel mode are unlikely to occur on a hot path
(as opposed to the user mode version which is invoked for VFP support
code and lazy restore), we can use the existing undef hook machinery for
any kernel mode instruction emulation that is needed, including calling
the existing vfp_kmode_exception() routine for unexpected cases. So drop
the call to call_fpe, and instead, install an undef hook that will get
called for NEON and VFP instructions that trigger an UND exception in
kernel mode.
While at it, make sure that the PC correction is accurate for the
execution mode where the exception was taken, by checking the PSR
Thumb bit.

ARM: dts: meson: fix PHY deassert timing requirements
[ Upstream commit
656ab1bdcd2b755dc161a9774201100d5bf74b8d ]
According to the datasheet (Rev. 1.9) the RTL8211F requires at least
72ms "for internal circuits settling time" before accessing the PHY
registers. On similar boards with the same PHY this fixes an issue where
Ethernet link would not come up when using ip link set down/up.

mtd: spi-nor: atmel: remove global protection flag
[ Upstream commit
e6204d4620276398ed7317d64c369813a1f96615 ]
This is considered bad for the following reasons:
(1) We only support the block protection with BPn bits for write
protection. Not all Atmel parts support this.
(2) Newly added flash chip will automatically inherit the "has
locking" support and thus needs to explicitly tested. Better
be opt-in instead of opt-out.
(3) There are already supported flashes which doesn't support
the locking scheme. So I assume this wasn't properly tested
before adding that chip; which enforces my previous argument
that locking support should be an opt-in.
Remove the global flag and add individual flags to all flashes which
supports BP locking. In particular the following flashes don't support
the BP scheme:
- AT26F004
- AT25SL321
- AT45DB081D
Please note, that some flashes which are marked as SPI_NOR_HAS_LOCK just
support Global Protection, i.e. not our supported block protection
locking scheme. This is to keep backwards compatibility with the
current "unlock all at boot" mechanism. In particular the following
flashes doesn't have BP bits:
- AT25DF041A
- AT25DF321
- AT25DF321A
- AT25DF641

mtd: spi-nor: ignore errors in spi_nor_unlock_all()
[ Upstream commit
bdb1a75e4b9df6861ec6a6e3e3997820d3cebabe ]
Just try to unlock the whole SPI-NOR flash array. Don't abort the
probing in case of an error. Justifications:
(1) For some boards, this just works because
spi_nor_write_16bit_sr_and_check() is broken and just checks the
second half of the 16bit. Once that will be fixed, SPI probe will
fail for boards which has hardware-write protected SPI-NOR flashes.
(2) Until now, hardware write-protection was the only viable solution
to use the block protection bits. This is because this very
function spi_nor_unlock_all() will be called unconditionally on
every linux boot. Therefore, this bits only makes sense in
combination with the hardware write-protection. If we would fail
the SPI probe on an error in spi_nor_unlock_all() we'd break
virtually all users of the block protection bits.
(3) We should try hard to keep the MTD working even if the flash might
not be writable/erasable.

platform/x86: intel-vbtn: Fix SW_TABLET_MODE always reporting 1 on some HP x360 models
[ Upstream commit
a4327979a19e8734ddefbd8bcbb73bd9905b69cd ]
Some HP x360 models have an ACPI VGBS method which sets bit 4 instead of
bit 6 when NOT in tablet mode at boot. Inspecting all the DSDTs in my DSDT
collection shows only one other model, the Medion E1239T ever setting bit 4
and it always sets this together with bit 6.
So lets treat bit 4 as a second bit which when set indicates the device not
being in tablet-mode, as we already do for bit 6.
While at it also prefix all VGBS constant defines with "VGBS_".
Note this wrokaround was first added to the kernel as
commit
d823346876a9 ("platform/x86: intel-vbtn: Fix SW_TABLET_MODE always
reporting 1 on the HP Pavilion 11 x360").
After commit
8169bd3e6e19 ("platform/x86: intel-vbtn: Switch to an
allow-list for SW_TABLET_MODE reporting") got added to the kernel this
was reverted, because with the new allow-list approach the workaround
was no longer necessary for the model on which the issue was first
reported.
But it turns out that the workaround is still necessary because some
affected models report a chassis-type of 31 which is on the allow-list.

set to =m, the mmal code never gets built, which in turn can
lead to link errors:

Change the Kconfig to depend on BCM2835_VCHIQ like the other drivers,
and remove the now redundant dependencies.

macintosh/adb-iop: Send correct poll command
[ Upstream commit
10199e90ee20e68859f8128331ec8d85b036d349 ]
The behaviour of the IOP firmware is not well documented but we do know
that IOP message reply data can be used to issue new ADB commands.
Use the message reply to better control autopoll behaviour by sending
a Talk Register 0 command after every ADB response, not unlike the
algorithm in the via-macii driver. This poll command is addressed to
that device which last received a Talk command (explicit or otherwise).

macintosh/adb-iop: Always wait for reply message from IOP
[ Upstream commit
2c9cfbadfa234b03473f1ef54e6f4772cc07a371 ]
A recent patch incorrectly altered the adb-iop state machine behaviour
and introduced a regression that can appear intermittently as a
malfunctioning ADB input device. This seems to be caused when reply
packets from different ADB commands become mixed up, especially during
the adb bus scan. Fix this by unconditionally entering the awaiting_reply
state after sending an explicit command, even when the ADB command won't
generate a reply from the ADB device.
It turns out that the IOP always generates reply messages, even when the
ADB command does not produce a reply packet (e.g. ADB Listen command).
So it's not really the ADB reply packets that are being mixed up, it's the
IOP messages that enclose them. The bug goes like this:
1. CPU sends a message to the IOP, expecting no response because this
message contains an ADB Listen command. The ADB command is now
considered complete.
2. CPU sends a second message to the IOP, this time expecting a
response because this message contains an ADB Talk command. This
ADB command needs a reply before it can be completed.
3. adb-iop driver receives an IOP message and assumes that it relates
to the Talk command. It's actually an empty one (with flags ==
ADB_IOP_EXPLICIT|ADB_IOP_TIMEOUT) for the previous command. The
Talk command is now considered complete but it gets the wrong reply
data.
4. adb-iop driver gets another IOP response message, which contains
the actual reply data for the Talk command, but this is dropped
(the driver is no longer in awaiting_reply state).

cpufreq: imx: fix NVMEM_IMX_OCOTP dependency
[ Upstream commit
fc928b901dc68481ba3e524860a641fe13e25dfe ]
A driver should not 'select' drivers from another subsystem.
If NVMEM is disabled, this one results in a warning:
WARNING: unmet direct dependencies detected for NVMEM_IMX_OCOTP
Depends on [n]: NVMEM [=n] && (ARCH_MXC [=y] || COMPILE_TEST [=y]) && HAS_IOMEM [=y]
Selected by [y]:
- ARM_IMX6Q_CPUFREQ [=y] && CPU_FREQ [=y] && (ARM || ARM64 [=y]) && ARCH_MXC [=y] && REGULATOR_ANATOP [=y]
Change the 'select' to 'depends on' to prevent it from going wrong,
and allow compile-testing without that driver, since it is only
a runtime dependency.
