Linux Properties

Property Description Customizable Optional Value
pwdn-gpios Should contain the list for GPIOs to control power in order of aggregator and camerainstances, tuples contain the GPIO interrupt number and triggering mode flag. Yes Yes N/A
pwr-items Map power items to the GPIO item specified in the pwdn-gpios list, starting from 0. Forexample, pwr-item 0 is for the deserializer, while pwr-item 1, 2, 3, 4 are for links 0, 1, 2, 3. Yes Yes N/A
default-power-on If this flag is present, while probing the device, pwdn-gpios are powered on. Yes Yes N/A
runtime-pwrctrl-off If this property is present, power control GPIOs retain the same status and are never changed. Yes Yes N/A
interrupt-parent Should contain interrupt parent for GPIO interrupt (phandle). Yes Yes <&tegra_main_gpio>
interrupts Should contain the GPIO interrupt number and triggering mode flag. Yes Yes <TEGRA194_MAIN_GPIO(P, 5) 2>

pwr_ctrl node

Property Description Customizable Optional Value
power_port The GPIO expander port that controls deserializer power. Required if the tca9539 node is present. No No 0
