Hold temporary memory for format conversion in an instance of struct drm_format_conv_state. Update internal helpers of DRM's format-conversion code accordingly. Drivers will later be able to maintain this cache by themselves. Besides caching, struct drm_format_conv_state will be useful to hold additional information for format conversion, such as palette data or foreground/background colors. This will enable conversion from indexed color formats to component-based formats. v5: * improve documentation (Javier, Noralf) v3: * rename struct drm_xfrm_buf to struct drm_format_conv_state (Javier) * remove managed cleanup * add drm_format_conv_state_copy() for shadow-plane support Signed-off-by:Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by:
