The tc358765 is similar to tc358775. The tc358765 just an earlier version
of the hardware, and it's pin and register compatible with tc358775 for

From the binding point of view the only difference is that the tc358765
does not have stdby-gpios.

The device uses a clock lane, and 1 to 4 DSI data lanes. Let's add the
data-lanes property starting at 1 similar to what the other bridge
bindings are doing.
Let's also drop the data-lanes properties in the example for the DSI host
controller to avoid confusion. The configuration of the DSI host depends
on the controller used and is unrelated to the bridge binding.

This change effectively reverts commit 586b286b11 ("dm crypt:
constrain crypt device's max_segment_size to PAGE_SIZE") and relies on
block core's late bio-splitting to ensure that dm-crypt's encryption
bios are split accordingly if they exceed the underlying device's
limits (e.g. max_segment_size).
Commit 586b286b11 was applied as a 4.3 fix for the benefit of
stable@ kernels 4.0+ just after block core's late bio-splitting was
introduced in 4.3 with commit 54efd50bfd ("block: make
generic_make_request handle arbitrarily sized bios"). Given block
core's late bio-splitting it is past time that dm-crypt make use of
it.
Also, given the recent need to revert meaningful progress that was
attempted during the 6.9 merge window (see commit bff4b74625 Revert
"dm: use queue_limits_set") this change allows DM core to safely make
use of queue_limits_set() without risk of breaking dm-crypt on NVMe.
Though it should be noted this commit isn't a prereq for reinstating
DM core's use of queue_limits_set() because blk_validate_limits() was
made less strict with commit b561ea56a2 ("block: allow device to
have both virt_boundary_mask and max segment size").

Dave and I were discussing some recent test regressions as a result of
me turning on nrext64=1 on realtime filesystems, when we noticed that
the minimum log size of a 32M filesystem jumped from 954 blocks to 4287
blocks.
Digging through xfs_log_calc_max_attrsetm_res, Dave noticed that @size
contains the maximum estimated amount of space needed for a local format
xattr, in bytes, but we feed this quantity to XFS_NEXTENTADD_SPACE_RES,
which requires units of blocks. This has resulted in an overestimation
of the minimum log size over the years.
We should nominally correct this, but there's a backwards compatibility
problem -- if we enable it now, the minimum log size will decrease. If
a corrected mkfs formats a filesystem with this new smaller log size, a
user will encounter mount failures on an uncorrected kernel due to the
larger minimum log size computations there.
Therefore, turn this on for parent pointers because it wasn't merged at
all upstream when this issue was discovered.

When an inode is removed, it may also cause the attribute fork to be
removed if it is the last attribute. This transaction gets flushed to
the log, but if the system goes down before we could inactivate the symlink,
the log recovery tries to inactivate this inode (since it is on the unlinked
list) but the verifier trips over the remote value and leaks it.
Hence we ended up with a file in this odd state on a "clean" mount. The
"obvious" fix is to prohibit erasure of the attr fork to avoid tripping
over the verifiers when pptrs are enabled.
