This a series of patches is a DRM Driver for Rockchip Socs, add support for vop devices, eDP. Future patches will add additional encoders/connectors, such as HDMI.
The basic "crtc" for rockchip is a "VOP" - Video Output Processor. the vop devices found on Rockchip rk3288 Soc, rk3288 soc have two similar Vop devices. Vop devices support iommu mapping, we use dma-mapping API with ARM_DMA_USE_IOMMU.
Changes in v2: - add DRM master device node to list all display nodes that comprise the graphics subsystem. - use the component framework to defer main drm driver probe until all VOP devices have been probed. - use dma-mapping API with ARM_DMA_USE_IOMMU, create dma mapping by master device and each vop device can shared the drm dma mapping. - use drm_crtc_init_with_planes and drm_universal_plane_init. - remove unnecessary middle layers. - add cursor set, move funcs to rockchip drm crtc. - use panel-simple driver for primary display. - add vop and edp reset.
Changes in v3: - change "crtc->fb" to "crtc->primary-fb" Adviced by Daniel Vetter - init cursor plane with universal api, remove unnecessary cursor set,move
Changes in v4: Adviced by David Herrmann - remove drm_platform_*() usage, use register drm device directly. Adviced by Rob Clark - remove special mmap ioctl, do userspace mmap with normal mmap() or mmap offset
Tested on rk3288 pinky board, use eDP encoders/connector, boot and display OK
