[PATCH v5 0/3] Support Sharp LQ101R1SX03 and HannStar HSD101PWW2 panels

This series adds support for Sharp LQ101R1SX03 and HannStar HSD101PWW2
display panels that are used by Asus Transformer tablets, which we're
planning to support since 5.17 kernel.

Changelog:
v5: - previously patches were sent by Dmitry and he asked me to resend them

v4: - Added r-b from Rob Herring that he gave to the LQ101R1SX01 DT patch
      of v2. I missed to add it to the v3 by accident.

v3: - No changes. Re-sending for 5.18. Device-trees of devices that use
      these panels were merged to 5.17, so we're missing the display support.

v2: - Added ack from Rob Herring to the HSD101PWW2 binding.

    - Updated LQ101R1SX01 binding, like it was suggested by Rob Herring,
      making LQ101R1SX03 directly compatible with the LQ101R1SX01.
      Such that ["sharp,lq101r1sx03", "sharp,lq101r1sx01"] could be
      used in DT. This removes need to update panel driver with the new
      compatible.

    - Improved commit message of the LQ101R1SX03 patch.

    - Added my s-o-b to all patches.

From: Anton Bambura <redacted>

LQ101R1SX03 is compatible with LQ101R1SX01 from software perspective,
document it. The LQ101R1SX03 is a newer revision of LQ101R1SX01, it has
minor differences in hardware pins in comparison to the older version.
The newer version of the panel can be found on Android tablets, like
ASUS TF701T.

Sam, could you please take a look at these patches? They missed two
kernel versions already because there was nobody to apply them. Thanks
in advance.

kernel versions already because there was nobody to apply them. Thanks
in advance.

I went through the panel backlog a week or two ago, but missed these.
Likely because I did not look more than a week back.
Sorry for letting it take so long - but I am not the most reliable linux
developer these days (hobby time only, and time is limited).

Patches are now applied to drm-misc (drm-misc-next) and should soon be
visible in -next.

That is totally fine. There are not that many full-time maintainers in
kernel.

Patches are now applied to drm-misc (drm-misc-next) and should soon be
visible in -next.

Awesome, thank you.
