Hi,
I would like to change the tx2 module’s RTC supply voltage to 3.0V,
and I try to add the to the ldo4 in your device tree:
regulator-min-microvolt = <3000000>;
regulator-max-microvolt = <3000000>;
spmic_ldo4: ldo4 {
regulator-name = “vdd-rtc”;
regulator-always-on;
regulator-boot-on;
maxim,active-fps-source = <MAX77620_FPS_SRC_DEF>;
};
But it not work.
Where is wrong with this? Or there is other way to configure the voltage?
