drm/panthor: Call panthor_gpu_coherency_init() after PM resume()
[ Upstream commit 7d5a3b22f5b58ef89ab8770d7a44c24eecde8d66 ]
When the device is coherent, panthor_gpu_coherency_init() will read
GPU_COHERENCY_FEATURES to make sure the GPU supports the ACE-Lite
coherency protocol, which will fail if the clocks/power-domains are
not enabled when the read is done. Move the
panthor_gpu_coherency_init() call after the device has been resumed
to prevent that.
Changes in v2:
- Add Liviu's R-b
Changes in v3:
- Add Steve's R-b
Fixes: dd7db8d911a1 ("drm/panthor: Explicitly set the coherency mode")
