Subject: [PATCH v9 0/9] drm/etnaviv: Add pci device driver support

From: Sui Jingfeng <suijingfeng@...ngson.cn>

There is a Vivante GC1000 (v5037) in LS2K1000 and LS7A1000, this GPU is a
PCI device, and it has 2D and 3D cores in the same core. This series is
trying to add PCI device driver support to etnaviv.

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 trivial stubs for the PCI driver (Bjorn)
	* Remove a redundant dev_err() usage (Bjorn)
	* Clean up etnaviv_pdev_probe() also.

Sui Jingfeng (9):
  drm/etnaviv: Add a dedicated function to register an irq handler
  drm/etnaviv: Add a dedicated function to get various clocks
  drm/etnaviv: Add dedicated functions to create and destroy platform
    device
  drm/etnaviv: Add helpers for private data construction and destruction
  drm/etnaviv: Allow bypass component framework
  drm/etnaviv: Add driver support for the PCI devices
  drm/etnaviv: Add support for the dma coherent device
  drm/etnaviv: Add a dedicated function to create the virtual master
  drm/etnaviv: Clean up etnaviv_pdev_probe() function
