This series is add PCI device driver wrapper, to support the Vivante GC1000
GPU in LS2K1000 and LS7A1000.

The whole serie have been tested on X86-64 and LoongArch platform, only the
kernel space driver are tested, basically normal and run stable!

v6:
	* Fix build issue on system without CONFIG_PCI enabled
v7:
	* Add a separate patch for the platform driver rearrangement (Bjorn)
	* Switch to runtime check if the GPU is dma coherent or not (Lucas)
	* Add ETNAVIV_PARAM_GPU_COHERENT to allow userspace to query (Lucas)
	* Remove etnaviv_gpu.no_clk member (Lucas)
	* Various Typos and coding style fixed (Bjorn)
v8:
	* Fix typos and remove unnecessary header included (Bjorn).
	* Add a dedicated function to create the virtual master platform
	  device.
v9:
	* Use PCI_VDEVICE() macro (Bjorn)
	* Add trivial stubs for the PCI driver (Bjorn)
	* Remove a redundant dev_err() usage (Bjorn)
	* Clean up etnaviv_pdev_probe() with etnaviv_of_first_available_node()
v10:
	* Add one more cleanup patch
	* Resolve the conflict with a patch from Rob
	* Make the dummy PCI stub inlined
	* Print only if the platform is dma-coherrent
V11:
	* Drop unnecessary changes (Lucas)
	* Tweak according to other reviews of v10.

V12:
	* Create a virtual platform device for the subcomponent GPU cores
	* Bind all subordinate GPU cores to the real PCI master via component.

Sui Jingfeng (8):
  drm/etnaviv: Add a helper function to get clocks
  drm/etnaviv: Add constructor and destructor for struct
    etnaviv_drm_private
  drm/etnaviv: Allow bypass component framework
  drm/etnaviv: Support for the vivante GPU core attached on PCI(e)
    device
  drm/etnaviv: Add support for cached coherent caching mode
  drm/etnaviv: Embed struct drm_device in struct etnaviv_drm_private
  drm/etnaviv: Add support for the JingJia Macro and LingJiu PCI(e) GPUs
  drm/etnaviv: Support binding multiple GPU cores with component
