dt-bindings: allow optional phys in Rockchip dw_hdmi

A patch from »drm/rockchip: hdmi support for rk3328« in state Mainline for linux-kernel

From: Heiko Stuebner <heiko@...> Date: Mon, 5 Feb 2018 15:08:14 +0100


Some newer Rockchip SoCs use an Innosilicon hdmiphy accessed via general mmio, so allow these to be referenced via the regular phy interfaces and therefore add optional phy-related properties to the binding. Signed-off-by: Heiko Stuebner <heiko@...> Reviewed-by: Rob Herring <robh@...>
