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.

Rebase the whole patches on top of Dave's drm-next branch [0] (Heiko)
Changes in v12.1:
- Use .enable instead of preprare/commit in encoder_helper_funcs (Heiko)
Changes in v12: None
Changes in v11: None
Changes in v10:
- Correct the ROCKCHIP_ANALOGIX_DP indentation in Kconfig to tabs here (Heiko)
Changes in v9: None
Changes in v8: None
Changes in v7: None
Changes in v6: None
Changes in v5:
- Remove the empty line at the end of document, and correct the endpoint
numbers in the example DT node, and remove the regulator iomux setting
in driver code while using the pinctl in devicetree instead. (Heiko)
- Add device type declared, cause the previous "platform device type
support (v4 11/16)" already merge into (v5 02/14).
- Implement connector registration code. (Thierry)
Changes in v4:
- Remove some deprecated DT properties in rockchip dp document.
Changes in v3:
- 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". (Thierry & Heiko)
- Add devicetree binding document. (Heiko)
- Remove "rockchip,panel" DT property, take use of remote point to get panel
node. (Heiko)
- Add the new function point dp_platdata->get_modes() init.
Changes in v2:
- Get panel node with remote-endpoint method, and create devicetree binding
for driver. (Heiko)
- Remove the clock enable/disbale with "sclk_edp" & "sclk_edp_24m",
leave those clock to rockchip dp phy driver.
