Subject: [PATCH] drm: renesas: Extend RZ/G2L supported KMS formats
From: Kieran Bingham <kieran.bingham+renesas@...asonboard.com>
The RZ/G2L driver utilises the VSPD to read data from input sources.
The rzg2l_du_kms component lists a restricted subset of the capabilities
of the VSPd which prevents additional formats from being used for
display planes.
The supported display plane formats are mapped in rzg2l_du_vsp_formats[].
Extend the rzg2l_du_format_infos[] table with the corresponding mappings
between the supported DRM formats and the formats exposed by the VSP in
rzg2l_du_vsp_formats, maintaining the same ordering in both tables.

Prior to this patch, kmstest reports all of these formats as supported
by the Planes, but using them fails during rzg2l_du_fb_create() as the
corresponding format isn't found in rzg2l_du_format_info.
This patch now lets me capture and render pixelformats from the Mali-C55
direct to an attached DSI panel on the Kakip board.
Patch tested with kms-tests:
