It looks like DRM_FORMAT_ARGB2101010 will require a bit more work, as DRM_FORMAT_XRGB2101010 is not handled by the DU driver at the moment. Let's do so with a patch on top of this series. There's no need to send a v2, I can handle the simple change in the commit message if you let me know whether my comment is right or wrong. > > + } > > + } > > + > > + return fourcc; > > +} > > + > > static void rcar_du_vsp_plane_setup(struct rcar_du_vsp_plane *plane) > > { > > struct rcar_du_vsp_plane_state *state = > > @@ -189,7 +220,7 @@ static void rcar_du_vsp_plane_setup(struct rcar_du_vsp_plane *plane) > > .alpha = state->state.alpha >> 8, > > .zpos = state->state.zpos, > > }; > > - u32 fourcc = state->format->fourcc; > > + u32 fourcc = rcar_du_vsp_state_get_format(state); > > unsigned int i; > > > > cfg.src.left = state->state.src.x1 >> 16; > > @@ -206,22 +237,6 @@ static void rcar_du_vsp_plane_setup(struct rcar_du_vsp_plane *plane) > > cfg.mem[i] = sg_dma_address(state->sg_tables[i].sgl) > > + fb->offsets[i]; > > > > - if (state->state.pixel_blend_mode == DRM_MODE_BLEND_PIXEL_NONE) { > > - switch (fourcc) { > > - case DRM_FORMAT_ARGB1555: > > - fourcc = DRM_FORMAT_XRGB1555; > > - break; > > - > > - case DRM_FORMAT_ARGB4444: > > - fourcc = DRM_FORMAT_XRGB4444; > > - break; > > - > > - case DRM_FORMAT_ARGB8888: > > - fourcc = DRM_FORMAT_XRGB8888; > > - break; > > - } > > - } > > - > > format = rcar_du_format_info(fourcc); > > cfg.pixelformat = format->v4l2; > >

Replying to myself again, the datasheet doesn't explicitly list DRM_FORMAT_XRGB2101010 as supported, but the generic mechanism to specify the location of the components should work fine for that format.
