[PATCH 05/21] ARM: dts: omap: Bind panel to panel-dpi instead of ti,tilcdc,panel driver
Kory Maincent (TI.com)

Wed Nov 26 09:35:47 PST 2025
Use panel-dpi driver instead of the deprecated tilcdc-panel driver in
preparation for removing the tilcdc-panel driver and binding.
Signed-off-by: Kory Maincent (TI.com) <kory.maincent at bootlin.com>

This patch is not tested. It would be nice if someone with one of this
board could test and validate it.
