Merge and cleanup the two headers into a single description of the object API. Also move all the documentation to the implementation and drop unnecessary includes from the header. No functional change. v2: minimal checkpatch.pl cleanup Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Arunpravin Paneer Selvam <Arunpravin.PaneerSelvam@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221125102137.1801-4-christian.koenig@amd.com
