[PATCH v3 0/2] drm/mediatek: Add ovl_adaptor get format function

[PATCH v3 0/2] drm/mediatek: Add ovl_adaptor get format function

[Nancy.Lin]

Add ovl_adaptor get_format and get_num_formats component function.
The two functions are needed for getting the supported format in
mtk_plane_init().

Changes in v3:
 - modify for reviewer's comment in v2.
   - add mdp-rdma get supported format api for ovl_adaptor driver.

Changes in v2:
 - remove change id

The mtk get_formats stuff seems like a lot of midlayering for not much
reasons? Is that really needed?

Just a drive-by questions I had while merging the pr.

In general, mediatek crtc directly control dma device such as OVL
(multiple plane), RDMA (single plane) and supported format information
store in these sub driver. MT8195 hardware use 4 RDMA to work like
OVL. To simplify the crtc control of dma device, we use a midlayer
OVL_Adaptor to control the 4 RDMA, so crtc just control one
OVL_Adaptor. crtc should query supported format from OVL_Adaptor, but
the supported format store in RDMA driver. That's why we have two
layer get_formats.

In general, mediatek crtc directly control dma device such as OVL
(multiple plane), RDMA (single plane) and supported format information
store in these sub driver. MT8195 hardware use 4 RDMA to work like
OVL. To simplify the crtc control of dma device, we use a midlayer
OVL_Adaptor to control the 4 RDMA, so crtc just control one
OVL_Adaptor. crtc should query supported format from OVL_Adaptor, but
the supported format store in RDMA driver. That's why we have two
layer get_formats.

Chun-Kuang.

[PATCH v3 2/2] drm/mediatek: Add ovl_adaptor get format function

[Nancy.Lin]

1. Add ovl_adaptor get_format and get_num_formats component function.
The two functions are needed for getting the supported format in
mtk_plane_init().
2. Get supported format from the ovl_adaptor's rdma engine - mdp_rdma.
