 HDMI PHY
 ========
-
-The HDMI PHY serializes the HDMI encoder's three channel 10-bit parallel
-output and drives the HDMI pads.
-
-Required properties:
-- compatible: "mediatek,<chip>-hdmi-phy"
-- reg: Physical base address and length of the module's registers
-- clocks: PLL reference clock
-- clock-names: must contain "pll_ref"
-- clock-output-names: must be "hdmitx_dig_cts" on mt8173
-- #phy-cells: must be <0>
-- #clock-cells: must be <0>

-Optional properties:
-- mediatek,ibias: TX DRV bias current for <1.65Gbps, defaults to 0xa
-- mediatek,ibias_up: TX DRV bias current for >1.65Gbps, defaults to 0x1c
