Hi Thomas, On Wed, Jul 27, 2022 at 01:33:04PM +0200, Thomas Zimmermann wrote:Update XRGB8888-to-RGB332 conversion to support struct iosys_map and convert all users. Although these are single-plane color formats, the new interface supports multi-plane formats for consistency with drm_fb_blit().

I need to find some time to review all patches, but this one LGTM.
Thanks a lot.
This series will cause conflicts with [1]. Depending on which patchset gets merged earlier, we will have to resolve the conflicts in one series or the other.
I've seen this. Go ahead and commit your patches if they are ready. I can easily rebase on top.
Best reards Thomas
