I agree v10 will simplify the code as I have do clean-ups based on your

Re: [PATCH v9 RESEND 4/5] drm: Add RZ/G2L DU Support
Hi Biju,
Thank you for the patch.
This is a partial review, because the driver is big, and because some
changes in v10 will (hopefully) simplify the code and make review
easier.

[PATCH v9 RESEND 4/5] drm: Add RZ/G2L DU Support
The LCD controller is composed of Frame Compression Processor (FCPVD),
Video Signal Processor (VSPD), and Display Unit (DU).
It has DPI/DSI interfaces and supports a maximum resolution of 1080p
along with 2 RPFs to support the blending of two picture layers and
raster operations (ROPs).
The DU module is connected to VSPD. Add RZ/G2L DU support for RZ/G2L
alike SoCs.

suggested by Philipp Zabel.
v7->v8:
* Dropped RCar du lib and created RZ/G2L DU DRM driver by creating rz_du
folder.
* Updated KConfig and Makefile.
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.
