* 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>;
};
};
};
...
};
