[PATCH v1 0/6] Add eDP support for RK3568

[Damon Ding <damon.ding@rock-chips.com>]

Rebased after:
https://lore.kernel.org/all/20260928081418.3605775-1-damon.ding@rock-chips.com/

PATCH 1 is to document the "rockchip,rk3568-edp" compatible in the
        Rockchip Analogix DP binding.
PATCH 2 is to add the binding for the RK3568 eDP PHY with NaNeng IP block.
PATCH 3 is to add the RK3568 support for the Analogix DP bridge driver.
PATCH 4 is to add the driver for the Rockchip eDP Transmitter PHY with
        NaNeng IP block.
PATCH 5 is to add the RK3568 support for the Rockchip Analogix DP driver.
PATCH 6 is to add the eDP controller and eDP PHY nodes for the RK3568
        SoCs.

Tested on RK3568 EVB1 baord with LG eDP panel LP079QX1-SP0V.
