+Analogix ANX7814 SlimPort (Full-HD Transmitter)
+-----------------------------------------------
+
+The ANX7814 is an ultra-low power Full-HD (1080p60) SlimPort transmitter
+designed for portable devices.
+
+Required properties:
+
+ - compatible           : "analogix,anx7814"
+ - reg                  : I2C address of the device
+ - interrupt-parent     : Should be the phandle of the interrupt controller
+                          that services interrupts for this device
+ - interrupts           : Should contain the INTP interrupt
+ - hpd-gpios            : Which GPIO to use for hpd
+ - pd-gpios             : Which GPIO to use for power down
+ - reset-gpios          : Which GPIO to use for reset
+
+Optional properties:
+
+ - dvdd10-supply        : Regulator for 1.0V digital core power.
+ - Video port for HDMI input, using the DT bindings defined in [1].

+Example:

+                interrupt-parent = <&gpio0>;
+                interrupts = <99 IRQ_TYPE_LEVEL_LOW>;   /* INTP */
+                hpd-gpios = <&pio 36 GPIO_ACTIVE_HIGH>;
+                pd-gpios = <&pio 33 GPIO_ACTIVE_HIGH>;
+                reset-gpios = <&pio 98 GPIO_ACTIVE_HIGH>;
+                port {
