RZ/G2L SoC embeds Mali-G31 bifrost GPU.
This patch series aims to add support for the same
It is tested with latest drm-misc-next + mesa 21.3.0 +
out of tree patch for (du + DSI) +
platfrom mesa configuration for RZ/G2L.
Tested the kmscube application.

Platform specific Mesa patch for RZ/G2L
---------------------
src/gallium/targets/dri/meson.build
+ 'rcar-du_dri.so',
src/gallium/targets/dri/target.c
+DEFINE_LOADER_DRM_ENTRYPOINT(rcar_du)
V1->V2:
* Removed clock patches from this seies, as it is accepted for 5.17
* Added Rb tag from Geert
* Added reset-names required property for RZ/G2L and updated the board dtsi.
