[PATCH v5 0/2] drm/panel: ilitek-ili9882t: Add support for Ilitek IL79900A-based panels

Posted by Langyan Ye 3 months, 1 week ago

This series adds support for the Tianma TL121BVMS07-00 panel, which uses
the Ilitek IL79900A display controller.

Following review feedback from Neil Armstrong, the IL79900A support has
been merged into the existing `panel-ilitek-ili9882t.c` driver instead of
creating a new one, since both controllers share similar command sequences
and initialization behavior.

Changes in v5:
- PATCH 1/2: No changes (already reviewed-by Conor Dooley)
- PATCH 2/2: Merge IL79900A support into existing panel-ilitek-ili9882t.c driver.
- Link to v4: https://lore.kernel.org/all/20251022124628.311544-1-yelangyan@huaqin.corp-partner.google.com/

Changes in v4:
- PATCH 1/2: Rename compatible to "tianma,tl121bvms07-00" and update example accordingly.
- PATCH 2/2: Update driver to use new compatible and rename related data structure.
- Link to v3: https://lore.kernel.org/all/20251016095043.1694736-1-yelangyan@huaqin.corp-partner.google.com/

Changes in v3:
- PATCH 1/2: Fix DT schema error for `backlight` property.
- PATCH 2/2: Address review feedback (use mipi_dsi_msleep/_multi, move init sequence to mode, minor cleanups).
- Link to v2: https://lore.kernel.org/all/20251010093751.2793492-1-yelangyan@huaqin.corp-partner.google.com/

Changes in v2:
- PATCH 1/2: Address Rob Herring’s review comments and align with panel-common.yaml conventions.
- PATCH 2/2: Rename driver to panel-ilitek-il79900a and align naming and structure with existing Ilitek panel drivers.
- Link to v1: https://lore.kernel.org/all/20250930075044.1368134-1-yelangyan@huaqin.corp-partner.google.com/
