[PATCH 0/7] Rockchip dw-mipi-dsi driver

[Chris Zhong]

Hi all

This is a bunch of dw-mipi-dsi driver for RK3399 and RK3288, they have
been tested on rk3399 and rk3288 evb board.

This series is based on Mark Yao's branch:
https://github.com/markyzq/kernel-drm-rockchip/tree/drm-rockchip-next-2016-05-23



Chris Zhong (7):
  dt-bindings: add rk3399 support for dw-mipi-rockchip
  DRM: mipi: support rk3399 mipi dsi
  dt-bindings: add power domain node for dw-mipi-rockchip
  drm/rockchip: dw-mipi: add dw-mipi power domain support
  drm/rockchip: dw-mipi: support HPD poll
  drm/rockchip: dw-mipi: fix phy clk lane stop state timeout
  drm/rockchip: dw-mipi: fix insufficient bandwidth of some panel

[PATCH 1/7] dt-bindings: add rk3399 support for dw-mipi-rockchip

[Chris Zhong]

The dw-mipi-dsi of rk3399 is almost the same as rk3288, the rk3399 has
additional phy config clock.

This is not really optional. It is required for rk3399. Document with 
the rest of the clocks and note this one is rk3399 only.
