Merge branch 'upstream/analogix-dp-20160705' of git://github.com/yakir-Yang/linux into drm-next

Please consider merging this tag, which contains the v4 misc fixes and add RK3399 eDP support patches[0] I sent on 2016-06-29, rebased onto v4.7-rc5.

* 'upstream/analogix-dp-20160705' of git://github.com/yakir-Yang/linux:
  dt-bindings: analogix_dp: rockchip: correct the wrong compatible name
  drm/rockchip: analogix_dp: introduce the pclk for grf
  drm/bridge: analogix_dp: fix no drm hpd event when panel plug in
  drm/rockchip: analogix_dp: update the comments about why need to hardcode VOP output mode
  drm/rockchip: analogix_dp: correct the connector display color format and bpc
  drm/bridge: analogix_dp: passing the connector as an argument in .get_modes()
  drm/rockchip: analogix_dp: make panel detect to an optional action
  drm/rockchip: analogix_dp: add rk3399 eDP support
  drm/bridge: analogix_dp: some rockchip chips need to flip REF_CLK bit setting
  drm/bridge: analogix_dp: correct the register bit define error in ANALOGIX_DP_PLL_REG_1
  drm/rockchip: analogix_dp: split the lcdc select setting into device data
