drm/rockchip: cdn-dp: add cdn DP support for rk3399 (1a0f7ed3) · Commits · 戴 / test

Add support for cdn DP controller which is embedded in the rk3399 SoCs. The DP is compliant with DisplayPort Specification, Version 1.3, This IP is compatible with the rockchip type-c PHY IP. There is a uCPU in DP controller, it need a firmware to work, please put the firmware file to /lib/firmware/rockchip/dptx.bin. The uCPU in charge of aux communication and link training, the host use mailbox to communicate with the ucpu. The dclk pin_pol of vop must not be invert for DP. Signed-off-by:
