The Working Sample R-Car SoCs may not yet have thermal sensor trimming
values programmed into fuses, those fuses are blank instead. For such
SoCs, the driver includes fallback trimming values. Those values are
currently applied to all SoCs which use this driver.
Introduce support for per-SoC fallback trimming values in preparation
for SoCs which do not use these current trimming values. No functional
change is intended here.

This commit fixes a potential race condition in the userqueue fence
signaling mechanism by replacing dma_fence_is_signaled_locked() with
dma_fence_is_signaled().
The issue occurred because:
1. dma_fence_is_signaled_locked() should only be used when holding
the fence's individual lock, not just the fence list lock
2. Using the locked variant without the proper fence lock could lead
to double-signaling scenarios:
- Hardware completion signals the fence
- Software path also tries to signal the same fence
By using dma_fence_is_signaled() instead, we properly handle the
locking hierarchy and avoid the race condition while still maintaining
the necessary synchronization through the fence_list_lock.

Reject modes with a pixel clock higher than the maximum display

With the addition of the YUV422 fallback, DC can now accidentally
select a mode requiring higher pixel clock than actually supported
when the DP version supports the required bandwidth but the clock
is otherwise too high for the display engine. DCE 6-10 don't
support these modes but they don't have a bandwidth calculation

[Why]
The main reason common modes are added is for compatibility with
clone mode when a laptop is connected to a projector or external
monitor. Since commit 978fa2f6d0 ("drm/amd/display: Use scaling
for non-native resolutions on eDP") when non-native modes are picked
for eDP the GPU scalar will be used. This is because it is inconsistent
whether eDP panels have the capability to actually drive non-native
resolutions. With panels connected to other connectors this limitation
generally doesn't exist as we the EDID will advertise support for a
number of resolutions and monitors will use built in scaling hardware.
Comparing DC and non-DC code paths the non-DC code path only adds
common modes for LVDS and eDP whereas the DC codepath does it for
all connector types.
In the past there was an experiment done to disable common mode adding
for eDP and LVDS from commit 6d396e7ac1 ("drm/amd/display: Disable
common modes for LVDS") and commit 7948afb46a ("drm/amd/display:
Disable common modes for eDP") but this was reverted in
commit a8b79b0918 ("drm/amd: Re-enable common modes for eDP and
LVDS") because it caused problems with Xorg.
[How]
Only add common modes for eDP and LVDS for DC, matching the behavior
of non-DC.

commit 530694f54d ("drm/amdgpu: do not resume device in thaw for

into S4 where the power would be turned off. Basically the thaw()
callback wouldn't resume the device if the hibernation image was
successfully created since the system would be powered off.
This however isn't the correct flow for a system entering into
s0i3 after the hibernation image is created. Some of the amdgpu
callbacks have different behavior depending upon the intended
state of the suspend.

Use pm_hibernation_mode_is_suspend() as an input to decide whether
to run resume during thaw() callback.

The following code paths may result in high latency or even task hangs:
1. fastcommit io is throttled by wbt.
2. jbd2_fc_wait_bufs() might wait for a long time while
JBD2_FAST_COMMIT_ONGOING is set in journal->flags, and then
jbd2_journal_commit_transaction() waits for the
JBD2_FAST_COMMIT_ONGOING bit for a long time while holding the write
lock of j_state_lock.
3. start_this_handle() waits for read lock of j_state_lock which
results in high latency or task hang.
Given the fact that ext4_fc_commit() already modifies the current

In June 2015, commit c290ea01ab ("fs: Remove ext3 filesystem driver")
removed the historic ext3 filesystem support as ext3 partitions are fully
supported with the ext4 filesystem support. To simplify updating the kernel
build configuration, which had only EXT3 support but not EXT4 support
enabled, the three config options EXT3_{FS,FS_POSIX_ACL,FS_SECURITY} were
kept, instead of immediately removing them. The three options just enable
the corresponding EXT4 counterparts when configs from older kernel versions
are used to build on later kernel versions. This ensures that the kernels
from those kernel build configurations would then continue to have EXT4
enabled for supporting booting from ext3 and ext4 file systems, to avoid
potential unexpected surprises.
Given that the kernel build configuration has no backwards-compatibility
guarantee and this transition phase for such build configurations has been
in place for a decade, we can reasonably expect all such users to have
transitioned to use the EXT4 config options in their config files at this
point in time. With that in mind, the three EXT3 config options are
obsolete by now.
Remove the obsolete EXT3 config options.

8a83ac5494 ("ext4: call bdev_getblk() from sb_getblk_gfp()"), meaning
the function can now fail under memory pressure.
Most callers of ext4_sb_bread() propagate the error to userspace and do not
remount the filesystem read-only. However, ext4_free_branches() handles
ext4_sb_bread() failure by remounting the filesystem read-only.
This implies that an ext3 filesystem (mounted via the ext4 driver) could be
forcibly remounted read-only due to a transient page allocation failure,
which is unacceptable.
To mitigate this, introduce a new helper function, ext4_sb_bread_nofail(),
which explicitly uses __GFP_NOFAIL, and use it in ext4_free_branches().

least one of the virtual USB ports are bound to an active USB/IP
connection.
However, in some cases, the detection logic doesn't work reliably, i.e.
when all devices attached to the virtual root hub have been already
suspended, leading to a broken suspend state, with unrecoverable resume.
Ensure the virtually attached devices do not enter suspend by setting
the syscore PM flag. Note this is currently limited to the client side
only, since the server side doesn't implement system suspend prevention.

Renesas have tried to minimize the occurrence of FSERR errors as much as
possible, but unfortunately we cannot remove them completely, because
MSIOF might setup its register during CLK/SYNC are inputed. It can be
happen because MSIOF is working as Clock/Frame Consumer.
Ignore 1st FSERR which we can do nothing

This driver is assuming MSIOF is used as Clock/Frame Consumer Mode, and
there is a case that some Codec (= Clock/Frame Provider) might output
Clock/Frame before setup MSIOF.
And, MSIOF will capture data without checking SYNC signal Hi/Low (= R/L).
This means, if MSIOF RXE bit was set as 1 in case of SYNC signal was Hi
(= R) timing, it will start capture data since next SYNC low signal (= L).
Because Linux assumes sound data is lined up as R->L->R->L->..., the data
R/L might be opposite.
The only solution in this case is start CLK/SYNC *after* MSIOF settings,
but it depends when and how Codec driver start it.

SITMDRn / SIRMDRn and some other registers should not be updated during
working even though it was not related the target direction (for example,
do TX settings during RX is working), otherwise it cause a FSERR.
Setup both direction (Playback/Capture) in the same time.

Current DMAC is stopped before HW stop, but it might be cause of
sync error. Stop HW first.

MSIOF TX/RX are sharing same clock. Adds .symmetric_xxx flags.
