[PATCH 0/1] Xe OA Consolidated Diffs

[Ashutosh Dixit]

Because Xe OA changes between successive revisions are distributed across
multiple patches, I am providing a combined diff of all changes in a single
patch to help with the code review.

These changes pertain to: https://patchwork.freedesktop.org/series/121084/

[PATCH 1/1] drm/xe/oa: Combined diff of changes between v9 and v10

[Ashutosh Dixit]

Because Xe OA changes between successive revisions are distributed across
multiple patches, provide a combined diff of all changes in a single patch
to help with the code review.

These changes pertain to: https://patchwork.freedesktop.org/series/121084/

This patch will not compile, it's purpose is to just provide the diff.

Changes between v9 and v10 include:
* Kernel-doc fixes
* Documentation/comment fixes
* Don't expose capabilities as OR of properties (Umesh)
* Define oa_status register bitfields (Umesh)
