* techpoint,tpxxxx Decoder
|
|
Required Properties:
|
- compatible: should be "techpoint,tpxxxx"
|
- clocks: reference to the 27M xvclk input clock.
|
- clock-names: should be "xvclk".
|
- dovdd-supply: Digital I/O voltage supply, 1.8 volts
|
- avdd-supply: Analog voltage supply, 3.3 volts
|
- dvdd-supply: Digital core voltage supply, 1.2 volts
|
- reset-gpios: Low active reset gpio
|
- pwdn-gpios: High active power-down gpio
|
|
Attention:
|
techpoint device address (7bit)
|
techpoint + evb reuse the power bus
