Hello,
This series adds the needed bindings to operate the PowerVR GPU on R-Car
D3 SoC.
Together with the D3 clock changes [1] and a still OOT patch for the PVR
driver [2], I'm able to load firmware.
powervr fd000000.gpu: [drm] loaded firmware powervr/rogue_22.67.54.30_v1.fw
powervr fd000000.gpu: [drm] FW version v1.0 (build 6889268 OS)
powervr fd000000.gpu: [drm] Unsupported quirks in firmware image
powervr fd000000.gpu: [drm] Unsupported enhancements in firmware image
powervr fd000000.gpu: [drm] Unsupported features in firmware image
[drm] Initialized powervr 1.0.0 for fd000000.gpu on minor 1
I can run vulkaninfo from mesa (need to add the driver to
pvr_drm_configs):
$ PVR_I_WANT_A_BROKEN_VULKAN_DRIVER=1 meson devenv -C builddir vulkaninfo

I can't run test Vulkan applications such as gears as the PVR driver do
not support all features need for GE8300, for example
simple_internal_parameter_format_v1, see [3].
