[RFC v2 0/1] drm: lima: devfreq and cooling device support

2019-12-28 Thread Martin Blumenstingl
This is my attempt at adding devfreq (and cooling device) support to the lima driver. I am seeking comments in two general areas: - regarding the integration into the existing lima code - for the actual devfreq code (I had to adapt the panfrost code slightly, because lima uses a bus and a GPU/co

In the previous version, the callback function mode_valid of drm_connector_helper_funcs directly returned MODE_OK. Now we will ensure that the resolution is correct and return MODE_OK, otherwise return MODE_NOMODE. Signed-off-by: Tian Tao Signed-off-by: Gong junjie --- drivers/gpu/drm/hisilicon

2019-12-28 Thread Martin Blumenstingl
Most platforms with a Mali-400 or Mali-450 GPU also have support for changing the GPU clock frequency. Add devfreq support so the GPU clock rate is updated based on the actual GPU usage when the "operating-points-v2" property is present in the board.dts. The actual devfreq code is taken from panfr
