Add missing kernel-doc for GPU buddy allocator flags, gpu_buddy_block, and gpu_buddy. The documentation covers block header fields, allocator roots, free trees, and allocation flags such as RANGE, TOPDOWN, CONTIGUOUS, CLEAR, and TRIM_DISABLE. Private members are marked with kernel-doc private markers and documented with regular comments. No functional changes. v2: - Corrected GPU_BUDDY_CLEAR_TREE and GPU_BUDDY_DIRTY_TREE index values (Arun) - Rebased after DRM buddy allocator moved to drivers/gpu/ - Updated commit message v3: - Document reserved bits 8:6 in header layout (Arun) - Fix checkpatch warning Cc: Christian König <christian.koenig@amd.com> Cc: Arunpravin Paneer Selvam <Arunpravin.PaneerSelvam@amd.com> Suggested-by: Matthew Auld <matthew.auld@intel.com> Signed-off-by: Sanjay Yadav <sanjay.kumar.yadav@intel.com> Reviewed-by: Arunpravin Paneer Selvam <Arunpravin.PaneerSelvam@amd.com> Signed-off-by: Arunpravin Paneer Selvam <Arunpravin.PaneerSelvam@amd.com> Link: https://patch.msgid.link/20260212092527.718455-5-sanjay.kumar.yadav@intel.com
