drm/format-helper: Add drm_fb_build_fourcc_list() helper

2022-09-12T07:15:49+00:00

Add drm_fb_build_fourcc_list() function that builds a list of supported formats from native and emulated ones. Helpful for all drivers that do format conversion as part of their plane updates. Update current caller. v3: * improve warnings on ignored formats (Sam) v2: * use u32 instead of uint32_t (Sam) * print a warning if output array is too small (Sam) * comment fixes (Sam) Signed-off-by: Thomas Zimmermann Reviewed-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20220905141648.22013-5-tzimmermann@suse.de

drm/format-helper: Rename parameter vmap to src
