Hi all,
This patch series adds support for 64-bit and poll register accessors in
the Panthor DRM driver and performs a cleanup of the 64-bit register
definitions.
The first patch introduces new accessor functions to simplify and
standardize 64-bit and polling register operations. The second patch
refactors the existing 64-bit register definitions for improved clarity
and consistency.
v4:
- [PATCH 1/2]:
- Fixed missing check against mask value in PWRTRANS register polling.
- Removed panthor_gpu_read_timestamp() and
panthor_gpu_read_timestamp_offset() in favour of direct register
access as they currently only serve as wrapper functions.
- [PATCH 2/2]:
- Updated the register names inline with the removal of the two
timestamp functions.
- Picked up Rb tags from Liviu and Steven
- Link to v3:
