[PATCH v4 08/16] drm: rockchip/dp: add rockchip platform dp driver
Rockchip have three clocks for dp controller, we leave pclk_edp
to analogix_dp driver control, and keep the sclk_edp_24m and
sclk_edp in platform driver.
Signed-off-by: Yakir Yang
---
Changes in v4:
- Remove some deprecated DT properties in rockchip dp document.
Changes in v3:
- Take Thierry Reding and Heiko suggest, leave "sclk_edp_24m" to rockchip
dp phy driver which name to "24m", and leave "sclk_edp" to analogix dp
core driver which name to "dp", and leave "pclk_edp" to rockchip dp platform
driver which name to "pclk".
- Take Heiko suggest, add devicetree binding document.
- Take Heiko suggest, remove "rockchip,panel" DT property, take use of remote
point to get panel node.
- Add the new function point analogix_dp_platdata.get_modes init.
Changes in v2:
- Take Heiko suggest, get panel node with remote-endpoint method,
and create devicetree binding for driver.
- Remove the clock enable/disbale with "sclk_edp" & "sclk_edp_24m",
leave those clock to rockchip dp phy driver.
