commit 01350185fe02ae3ea2c12d578e06af0d5186f33e upstream.
The desired clock frequency was correctly set to 400MHz in the device tree
but was lowered by the driver to 300MHz breaking 4K 60Hz content playback.
Fix the issue by removing the driver call to clk_set_rate(), which reduce
the amount of board specific code.

commit 3e43442d4994c9e1e202c98129a87e330f7faaed upstream.
The pixel_array control size was calculated incorrectly:
the dimensions were swapped (dims[0] should be the height), and the
values should be the width or height divided by PIXEL_ARRAY_DIV
and rounded up. So don't use roundup, but use DIV_ROUND_UP instead.
This bug is harmless in the sense that nothing will break, except that
it consumes way too much memory for this control.

commit 020f602b068c9ce18d5056d02c8302199377d98d upstream.
Hynix hi556 support 8 test pattern modes:
hi556_test_pattern_menu[] = {
{
"Disabled",
"Solid Colour",
"100% Colour Bars",
"Fade To Grey Colour Bars",
"PN9",
"Gradient Horizontal",
"Gradient Vertical",
"Check Board",
"Slant Pattern",
}
The test pattern is set by a 8-bit register according to the
specification.
+--------+-------------------------------+
| BIT[0] | Solid color |
+--------+-------------------------------+
| BIT[1] | Color bar |
+--------+-------------------------------+
| BIT[2] | Fade to grey color bar |
+--------+-------------------------------+
| BIT[3] | PN9 |
+--------+-------------------------------+
| BIT[4] | Gradient horizontal |
+--------+-------------------------------+
| BIT[5] | Gradient vertical |
+--------+-------------------------------+
| BIT[6] | Check board |
+--------+-------------------------------+
| BIT[7] | Slant pattern |
+--------+-------------------------------+
Based on function above, current test pattern programming is wrong.
This patch fixes it by 'BIT(pattern - 1)'. If pattern is 0, driver
will disable the test pattern generation and set the pattern to 0.

commit aef89c0b2417da79cb2062a95476288f9f203ab0 upstream.
This sd_init() function reads the firmware. The firmware data holds a
series of records and the function reads each record and sends the data
to the device. The request_ihex_firmware() function
calls ihex_validate_fw() which ensures that the total length of all the
records won't read out of bounds of the fw->data[].
However, a potential issue is if there is a single very large
record (larger than PAGE_SIZE) and that would result in memory
corruption. Generally we trust the firmware, but it's always better to
double check.

commit b6bcbce3359619d05bf387d4f5cc3af63668dbaa upstream.
After commit 13a4b7fb6260 ("pmdomain: core: Leave powered-on genpds on
until late_initcall_sync") was applied, the Tegra210 Jetson TX1 board
failed to boot. Looking into this issue, before this commit was applied,
if any of the Tegra power-domains were in 'on' state when the kernel
booted, they were being turned off by the genpd core before any driver
had chance to request them. This was purely by luck and a consequence of
the power-domains being turned off earlier during boot. After this
commit was applied, any power-domains in the 'on' state are kept on for
longer during boot and therefore, may never transitioned to the off
state before they are requested/used. The hang on the Tegra210 Jetson
TX1 is caused because devices in some power-domains are accessed without
the power-domain being turned off and on, indicating that the
power-domain is not in a completely on state.
>From reviewing the Tegra PMC driver code, if a power-domain is in the
'on' state there is no guarantee that all the necessary clocks
associated with the power-domain are on and even if they are they would
not have been requested via the clock framework and so could be turned
off later. Some power-domains also have a 'clamping' register that needs
to be configured as well. In short, if a power-domain is already 'on' it
is difficult to know if it has been configured correctly. Given that the
power-domains happened to be switched off during boot previously, to
ensure that they are in a good known state on boot, fix this by
switching off any power-domains that are on initially when registering
the power-domains with the genpd framework.
Note that commit 05cfb988a4d0 ("soc/tegra: pmc: Initialise resets
associated with a power partition") updated the
tegra_powergate_of_get_resets() function to pass the 'off' to ensure
that the resets for the power-domain are in the correct state on boot.
However, now that we may power off a domain on boot, if it is on, it is
better to move this logic into the tegra_powergate_add() function so
that there is a single place where we are handling the initial state of
the power-domain.

commit 10a886aaed293c4db3417951f396827216299e3d upstream.
vhost_vsock_alloc_skb() returns NULL for packets advertising a length
larger than VIRTIO_VSOCK_MAX_PKT_BUF_SIZE in the packet header. However,
this is only checked once the SKB has been allocated and, if the length
in the packet header is zero, the SKB may not be freed immediately.
Hoist the size check before the SKB allocation so that an iovec larger
than VIRTIO_VSOCK_MAX_PKT_BUF_SIZE + the header size is rejected
outright. The subsequent check on the length field in the header can
then simply check that the allocated SKB is indeed large enough to hold
the packet.

commit 2e6ea70690ddd1ffa422423fd0d4523e4dfe4b62 upstream.
According to Documentation/PCI/endpoint/pci-endpoint-cfs.rst, the Endpoint
controller (EPC) should only start the link when userspace writes '1' to
the '/sys/kernel/config/pci_ep/controllers/<EPC>/start' attribute, which
ultimately results in calling imx_pcie_start_link() via
pci_epc_start_store().
To align with the documented behavior, do not start the link automatically
when adding the EP controller.

commit d31eb217425591e100b475fad6360cd3da2073c6 upstream.
apps_reset corresponds to LTSSM_EN in i.MX7, i.MX8MQ, i.MX8MM and i.MX8MP
platforms. Since assertion/de-assertion of apps_reset is done in
imx_pcie_ltssm_enable() and imx_pcie_ltssm_disable(), remove it from
imx_pcie_assert_core_reset() and imx_pcie_deassert_core_reset().
This also fixes a failure in enumerating the PI7C9X2G608GP (hotplug) chip
reliably on i.MX8MM, as reported by Tim.
It should be noted that only i.MX7D, i.MX8MQ, i.MX8MM, and i.MX8MP
platforms have the apps_reset logic, so this change doesn't have any effect
on other platforms.

commit 910bdb8197f9322790c738bb32feaa11dba26909 upstream.
An endpoint driver configfs attributes group is added to the
epf_group list of struct pci_epf_driver by pci_epf_add_cfs() but an
added group is not removed from this list when the attribute group is
unregistered with pci_ep_cfs_remove_epf_group().
Add the missing list_del() call in pci_ep_cfs_remove_epf_group()
to correctly remove the attribute group from the driver list.
With this change, once the loop over all attribute groups in
pci_epf_remove_cfs() completes, the driver epf_group list should be
empty. Add a WARN_ON() to make sure of that.

commit 1d60796a62f327cd9e0a6a0865ded7656d2c67f9 upstream.
The PCIe port driver erroneously creates a subdevice for hotplug on ACPI
slots which are handled by the ACPI hotplug driver.
Avoid by checking the is_pciehp flag instead of is_hotplug_bridge when
deciding whether to create a subdevice. The latter encompasses ACPI slots
whereas the former doesn't.
The superfluous subdevice has no real negative impact, it occupies memory
and interrupt resources but otherwise just sits there waiting for
interrupts from the slot that are never signaled.

commit 2e3a7476ec3989e77270b9481e76e137824b17c0 upstream.
Commit ff67592cbdfc ("mtd: spi-nor: Introduce spi_nor_set_mtd_info()")
moved all initialization of the mtd fields at the end of spi_nor_scan().
Normally, the mtd info is only needed for the mtd ops on the device,
with one exception: spi_nor_try_unlock_all(), which will also make use
of the mtd->size parameter. With that commit, the size will always be
zero because it is not initialized. Fix that by not using the size of
the mtd_info struct, but use the size from struct spi_nor_flash_parameter.

commit 9c62e2282900332c8b711d9f9e37af369a8ef71b upstream.
The Linux hwmon sysfs API values for pwmX_auto_pointY_pwm represent an
integer value between 0 (0%) to 255 (100%) and the pwmX_auto_pointY_temp
represent millidegrees Celcius.
Commit a6d80df47ee2 ("hwmon: (gsc-hwmon) fix fan pwm temperature
scaling") properly addressed the incorrect scaling in the
pwm_auto_point_temp_store implementation but erroneously scaled
the pwm_auto_point_pwm_show (pwm value) instead of the
pwm_auto_point_temp_show (temp value) resulting in:
# cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_pwm
25500
# cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_temp

# cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_temp

commit f21d136caf8171f94159d975ea4620c164431bd9 upstream.
The period generated by the hardware is
(PWMDWIDTH + 1) << CLKDIV) / freq
according to my tests with a signal analyser and also the documentation.
The current algorithm doesn't consider the `+ 1` part and so configures
slightly too high periods. The same issue exists for the duty cycle
setting. So subtract 1 from both the register values for period and
duty cycle. If period is 0, bail out, if duty_cycle is 0, just disable
the PWM which results in a constant low output.

commit 65c6f742ab14ab1a2679fba72b82dcc0289d96f1 upstream.
As per the i.MX93 TRM, section 67.3.2.1 "MOD register update", the value
of the TPM counter does NOT get updated when writing MOD.MOD unless
SC.CMOD != 0. Therefore, with the current code, assuming the following
sequence:
1) pwm_disable()
2) pwm_apply_might_sleep() /* period is changed here */
3) pwm_enable()
and assuming only one channel is active, if CNT.COUNT is higher than the
MOD.MOD value written during the pwm_apply_might_sleep() call then, when
re-enabling the PWM during pwm_enable(), the counter will end up resetting
after UINT32_MAX - CNT.COUNT + MOD.MOD cycles instead of MOD.MOD cycles as
normally expected.
Fix this problem by forcing a reset of the TPM counter before MOD.MOD is
written.

Fix the setting of the ODR register value in the probe function for

other chips (0x7 vs. 0x0) and 0 is a reserved value on that chip.
The driver already has this information available in odr_start_value
and uses it when checking valid values when writing to the
sampling_frequency attribute, but failed to set the correct initial
value in the probe function.

commit 1d9a21ffb43b6fd326ead98f0d0afd6d104b739a upstream.
Fix the channel index values passed to ad_sd_calibrate() in
ad7173_calibrate_all().
ad7173_calibrate_all() expects these values to be that of the CHANNELx
register assigned to the channel, not the datasheet INPUTx number of the
channel. The incorrect values were causing register writes to fail for
some channels because they set the WEN bit that must always be 0 for
register access and set the R/W bit to read instead of write. For other
channels, the channel number was just wrong because the CHANNELx
registers are generally assigned in reverse order and so almost never
match the INPUTx numbers.

Change the buffer disable callback from postdisable to predisable.
This balances the existing posteanble callback. Using postdisable
with posteanble can be problematic, for example, if update_scan_mode
fails, it would call postdisable without ever having called posteanble,
so the drivers using this would be in an unexpected state when
postdisable was called.

commit 399b883ec828e436f1a721bf8551b4da8727e65b upstream.
Fix a potential out-of-bounds array access of the hw_xlate array in
bno055.c.
In bno055_get_regmask(), hw_xlate was iterated over the length of the
vals array instead of the length of the hw_xlate array. In the case of
bno055_gyr_scale, the vals array is larger than the hw_xlate array,
so this could result in an out-of-bounds access. In practice, this
shouldn't happen though because a match should always be found which
breaks out of the for loop before it iterates beyond the end of the
hw_xlate array.
By adding a new hw_xlate_len field to the bno055_sysfs_attr, we can be
sure we are iterating over the correct length.

commit 58768b0563916ddcb73d8ed26ede664915f8df31 upstream.
Delete extra checks for the ATA_DFLAG_CDL_ENABLED flag that prevent
SET FEATURES command from being issued to a drive when NCQ commands
are active.
ata_mselect_control_ata_feature() sets / clears the ATA_DFLAG_CDL_ENABLED
flag during the translation of MODE SELECT to SET FEATURES. If SET FEATURES
gets deferred due to outstanding NCQ commands, the original MODE SELECT
command will be re-queued. When the re-queued MODE SELECT goes through
the ata_mselect_control_ata_feature() translation again, SET FEATURES
will not be issued because ATA_DFLAG_CDL_ENABLED has been already set or
cleared by the initial translation of MODE SELECT.
The ATA_DFLAG_CDL_ENABLED checks in ata_mselect_control_ata_feature()
are safe to remove because scsi_cdl_enable() implements a similar logic
that avoids enabling CDL if it has been enabled already.

commit 6de7435e6b81fe52c0ab4c7e181f6b5decd18eb1 upstream.
Intel MTL-like host controllers support auto-hibernate. Using
auto-hibernate with manual (driver initiated) hibernate produces more
complex operation. For example, the host controller will have to exit
auto-hibernate simply to allow the driver to enter hibernate state
manually. That is not recommended.
The default rpm_lvl and spm_lvl is 3, which includes manual hibernate.
Change the default values to 2, which does not.
Note, to be simpler to backport to stable kernels, utilize the UFS PCI
driver's ->late_init() call back. Recent commits have made it possible
to set up a controller-specific default in the regular ->init() call
back, but not all stable kernels have those changes.

commit 4428ddea832cfdb63e476eb2e5c8feb5d36057fe upstream.
UFSHCD core disables the UIC completion interrupt when issuing UIC
hibernation commands, and re-enables it afterwards if it was enabled to
start with, refer ufshcd_uic_pwr_ctrl(). For Intel MTL-like host
controllers, accessing the register to re-enable the interrupt disrupts
the state transition.
Use hibern8_notify variant operation to disable the interrupt during the
entire hibernation, thereby preventing the disruption.

commit d2be9ea9a75550a35c5127a6c2633658bc38c76b upstream.
ata_gen_ata_sense() is always called for a failed qc missing sense data
so that a sense key, code and code qualifier can be generated using
ata_to_sense_error() from the qc status and error fields of its result
task file. However, if the qc does not have its result task file filled,
ata_gen_ata_sense() returns early without setting a sense key.
Improve this by defaulting to returning ABORTED COMMAND without any
additional sense code, since we do not know the reason for the failure.
The same fix is also applied in ata_gen_passthru_sense() with the
additional check that the qc failed (qc->err_mask is set).

commit cf3fc037623c54de48d2ec1a1ee686e2d1de2d45 upstream.
Commit 8ae720449fca ("libata: whitespace fixes in ata_to_sense_error()")
inadvertantly added the entry 0x40 (ATA_DRDY) to the stat_table array in
the function ata_to_sense_error(). This entry ties a failed qc which has
a status filed equal to ATA_DRDY to the sense key ILLEGAL REQUEST with
the additional sense code UNALIGNED WRITE COMMAND. This entry will be
used to generate a failed qc sense key and sense code when the qc is
missing sense data and there is no match for the qc error field in the
sense_table array of ata_to_sense_error().
As a result, for a failed qc for which we failed to get sense data (e.g.
read log 10h failed if qc is an NCQ command, or REQUEST SENSE EXT
command failed for the non-ncq case, the user very often end up seeing
the completely misleading "unaligned write command" error, even if qc
was not a write command. E.g.:
sd 0:0:0:0: [sda] tag#12 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_OK cmd_age=0s
sd 0:0:0:0: [sda] tag#12 Sense Key : Illegal Request [current]
sd 0:0:0:0: [sda] tag#12 Add. Sense: Unaligned write command
sd 0:0:0:0: [sda] tag#12 CDB: Read(10) 28 00 00 00 10 00 00 00 08 00
I/O error, dev sda, sector 4096 op 0x0:(READ) flags 0x80700 phys_seg 1 prio class 0
Fix this by removing the ATA_DRDY entry from the stat_table array so
that we default to always returning ABORTED COMMAND without any
additional sense code, since we do not know any better. The entry 0x08
(ATA_DRQ) is also removed since signaling ABORTED COMMAND with a parity
error is also misleading (as a parity error would likely be signaled
through a bus error). So for this case, also default to returning
ABORTED COMMAND without any additional sense code. With this, the
previous example error case becomes:
sd 0:0:0:0: [sda] tag#17 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_OK cmd_age=0s
sd 0:0:0:0: [sda] tag#17 Sense Key : Aborted Command [current]
sd 0:0:0:0: [sda] tag#17 Add. Sense: No additional sense information
sd 0:0:0:0: [sda] tag#17 CDB: Read(10) 28 00 00 00 10 00 00 00 08 00
I/O error, dev sda, sector 4096 op 0x0:(READ) flags 0x80700 phys_seg 1 prio class 0
Together with these fixes, refactor stat_table to make it more readable
by putting the entries comments in front of the entries and using the
defined status bits macros instead of hardcoded values.

commit e6327c4acf925bb6d6d387d76fc3bd94471e10d8 upstream.
The "is_waiting" flag was updated after calling complete(), which could
lead to a race where the waiting thread wakes up before the flag is
cleared. This may cause a missed wakeup or stale state check.
Reorder the operations to update "is_waiting" before signaling completion
to ensure consistent state.

commit 01aad16c2257ab8ff33b152b972c9f2e1af47912 upstream.
On Google gs101, the number of UTP transfer request slots (nutrs) is 32,
and in this case the driver ends up programming the UTRL_NEXUS_TYPE
incorrectly as 0.
This is because the left hand side of the shift is 1, which is of type
int, i.e. 31 bits wide. Shifting by more than that width results in
undefined behaviour.
Fix this by switching to the BIT() macro, which applies correct type
casting as required. This ensures the correct value is written to
UTRL_NEXUS_TYPE (0xffffffff on gs101), and it also fixes a UBSAN shift
warning:
UBSAN: shift-out-of-bounds in drivers/ufs/host/ufs-exynos.c:1113:21
shift exponent 32 is too large for 32-bit type 'int'
For consistency, apply the same change to the nutmrs / UTMRL_NEXUS_TYPE
write.
