+* Analog Devices adv7343 video encoder
+
+The ADV7343 are high speed, digital-to-analog video encoders in a 64-lead LQFP
+package. Six high speed, 3.3 V, 11-bit video DACs provide support for composite
+(CVBS), S-Video (Y-C), and component (YPrPb/RGB) analog outputs in standard
+definition (SD), enhanced definition (ED), or high definition (HD) video
+formats.
+
+Required Properties :
+- compatible: Must be "adi,adv7343"
+
+Optional Properties :
+- adi,power-mode-sleep-mode: on enable the current consumption is reduced to
+ micro ampere level. All DACs and the internal PLL
+ circuit are disabled.
+- adi,power-mode-pll-ctrl: PLL and oversampling control. This control allows
+ internal PLL 1 circuit to be powered down and the
+ oversampling to be switched off.
+- ad,adv7343-power-mode-dac: array configuring the power on/off DAC's 1..6,
+ 0 = OFF and 1 = ON, Default value when this
+ property is not specified is <0 0 0 0 0 0>.
+- ad,adv7343-sd-config-dac-out: array configure SD DAC Output's 1 and 2, 0 = OFF
+ and 1 = ON, Default value when this property is
+ not specified is <0 0>.
+
+Example:
+
+i2c0@1c22000 {
+ ...
+ ...
+
+ adv7343@2a {
+ compatible = "adi,adv7343";
+ reg = <0x2a>;
+
+ port {
+ adv7343_1: endpoint {
+ adi,power-mode-sleep-mode;
+ adi,power-mode-pll-ctrl;
+ /* Use DAC1..3, DAC6 */
+ adi,dac-enable = <1 1 1 0 0 1>;
+ /* Use SD DAC output 1 */
+ adi,sd-dac-enable = <1 0>;
+ };
+ };
+ };
+ ...
+};
