Subject: [RESENT PATCH v7 0/3] Add drm driver for Rockchip Socs
Date: Fri, 26 Sep 2014 18:53:20 +0800	[thread overview]
Message-ID: <1411728800-25112-1-git-send-email-mark.yao@rock-chips.com> (raw)

This a series of patches is a DRM Driver for Rockchip Socs, add support
for vop devices. Future patches will add additional encoders/connectors,
such as eDP, 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.

Resent v7 email to fix mail style.

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.
- add vop 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

Changes in v5:
Adviced by Arnd Bergmann
- doing DMA start with a 32-bit masks with dma_mask and dma_coherent_mark
- fix some incorrect dependencies.
Adviced by Boris BREZILLON
- fix some mistake and bugs. 
Adviced by Daniel Vetter
- drop all special ioctl and use generic kms ioctl instead.
Adviced by Rob Clark
- use unlocked api for drm_fb_helper_restore_fbdev_mode.
- remove unused rockchip_gem_prime_import_sg_table.

Changes in v6:
- set gem buffer pitch 64 bytes align, needed by mali gpu.
Adviced by Daniel Kurtz
- fix some mistake, bugs, remove unused define, more better code style etc. 
- use clk_prepare()/unprepare() at probe()/remove() and clk_enable()/disable()
  at runtime instead of clk_prepare_enable().
- provide a help function from vop for encoder to do mode config, instead of
  using drm_diaplay_mode private method.
- change vop mode_set timing to make it more safely. 

Changes in v7:
- fix memory leakage problem.
