-Mediatek HDMI Encoder
-=====================
-
-The Mediatek HDMI encoder can generate HDMI 1.4a or MHL 2.0 signals from
-its parallel input.
-
-Required properties:
-- compatible: Should be "mediatek,<chip>-hdmi".
-- reg: Physical base address and length of the controller's registers
-- interrupts: The interrupt signal from the function block.
-- clocks: device clocks
- See Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
-- clock-names: must contain "pixel", "pll", "bclk", and "spdif".
-- phys: phandle link to the HDMI PHY node.
- See Documentation/devicetree/bindings/phy/phy-bindings.txt for details.
-- phy-names: must contain "hdmi"
-- mediatek,syscon-hdmi: phandle link and register offset to the system
- configuration registers. For mt8173 this must be offset 0x900 into the
- MMSYS_CONFIG region: <&mmsys 0x900>.
-- ports: A node containing input and output port nodes with endpoint
- definitions as documented in Documentation/devicetree/bindings/graph.txt.
-- port@0: The input port in the ports node should be connected to a DPI output
- port.
-- port@1: The output port in the ports node should be connected to the input
- port of a connector node that contains a ddc-i2c-bus property, or to the
- input port of an attached bridge chip, such as a SlimPort transmitter.
-
-HDMI CEC
-========
-
-The HDMI CEC controller handles hotplug detection and CEC communication.
-
-Required properties:
-- compatible: Should be "mediatek,<chip>-cec"
-- reg: Physical base address and length of the controller's registers
-- interrupts: The interrupt signal from the function block.
-- clocks: device clock
-
-HDMI DDC
-========
-
-The HDMI DDC i2c controller is used to interface with the HDMI DDC pins.
-The Mediatek's I2C controller is used to interface with I2C devices.
-
-Required properties:
-- compatible: Should be "mediatek,<chip>-hdmi-ddc"
-- reg: Physical base address and length of the controller's registers
-- clocks: device clock
-- clock-names: Should be "ddc-i2c".
-
-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
