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:
v3: - No changes. Re-sending for 5.18. Device-trees of devices that use these panels were merge 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.

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.
