Stop reaching into other components' registers directly and route those operations through the component that owns them. Move the timestamp/coherency helpers into panthor_gpu, add a doorbell helper, and update call sites accordingly. This keeps register knowledge local to each block and avoids spreading cross-component register accesses across the driver. This is a preparatory cleanup for using per-component iomem bases. v3: - Pick up Ack from Boris and R-bs from Liviu and Steve v2: - Fix incorrect spelling of timestamp helpers - Fix unintended trailing backslash Reviewed-by: Steven Price <steven.price@arm.com> Reviewed-by: Liviu Dudau <liviu.dudau@arm.com> Acked-by: Boris Brezillon <boris.brezillon@collabora.com> Signed-off-by: Karunika Choo <karunika.choo@arm.com> Tested-by: Boris Brezillon <boris.brezillon@collabora.com> Signed-off-by: Liviu Dudau <liviu.dudau@arm.com> Link: https://patch.msgid.link/20260427155934.416502-4-karunika.choo@arm.com
