[PATCH v7 0/8] Add RZ/{G2L,G2LC} and RZ/V2L DU support

[Biju Das]

RZ/G2L LCD controller composed of Frame compression Processor(FCPVD), Video
signal processor (VSPD) and Display unit(DU). The output of LCDC is
connected to Display parallel interface and MIPI link video interface.
 
The output from DSI is connected to ADV7535.

Created new CRTC/DRM driver specific to RZ/G2L alike SoCs using RCar DU lib.

This patch series tested on SMARC EVK based on RZ/{G2L,G2LC} and RZ/V2L SoCs.

This patch series depend upon [1]

v6->v7:
 * Split DU lib and  RZ/G2L du driver as separate patch series as
   DU support added to more platforms based on RZ/G2L alike SoCs.
 * Rebased to latest drm-tip.
 * Added patch #2 for binding support for RZ/V2L DU
 * Added patch #4 for driver support for RZ/V2L DU
 * Added patch #5 for SoC DTSI support for RZ/G2L DU
 * Added patch #6 for SoC DTSI support for RZ/V2L DU
 * Added patch #7 for Enabling DU on SMARC EVK based on RZ/{G2L,V2L} SoCs.
 * Added patch #8 for Enabling DU on SMARC EVK based on RZ/G2LC SoC.
