[PATCH v5 09/20] dt-bindings: display: renesas,rzg2l-du: Add support for RZ/G3E SoC
Posted by Tommaso Merciai 1 month, 2 weeks ago
The RZ/G3E Soc has 2 LCD controller (LCDC), contain a Frame Compression
Processor (FCPVD), a Video Signal Processor (VSPD), Video Signal
Processor (VSPD), and Display Unit (DU).

 - LCDC0 supports DSI and LVDS (single or dual-channel) outputs.
 - LCDC1 supports DSI, LVDS (single-channel), and RGB outputs.

Add new SoC-specific compatible string 'renesas,r9a09g047-du'.

v4->v5:
 - Dropped renesas,id property and updated bindings
   accordingly.

v2->v3:
 - No changes.

v2->v3:
 - No changes.

v1->v2:
 - Use single compatible string instead of multiple compatible strings
   for the two DU instances, leveraging a 'renesas,id' property to
   differentiate between DU0 and DU1.
 - Updated commit message accordingly.
