Subject: [PATCH v2 2/4] drm/rockchip: dw_hdmi: add RK3399 HDMI support
RK3399 and RK3288 shared the same HDMI IP controller, only some light
difference with GRF configure.
base on Yakir Yang's rk3399 patch, rebase to newest upstrem kernel:
https://patchwork.kernel.org/patch/9223323
Signed-off-by: Mark Yao <mark.yao@...k-chips.com>
Signed-off-by: Yakir Yang <ykk@...k-chips.com>
Changes in v2:
reuse hdmi_phy_configure_dwc_hdmi_3d_tx for phy configure
