I2S1 Controller and Voltage Regulators

Hi,

In Tx1 board, for I2S controllers, the regulator are assigned as:

i2s@702d1000
{
regulator-supplies = “vdd-1v8-audio-hv”, “vdd-1v8-audio-hv-bias”;
vdd-1v8-audio-hv-supply = <&max77620_sd3>;
vdd-1v8-audio-hv-bias-supply = <&max77620_sd3>;
};

Need to test the I2S1 controller in Jetson Tx2 board, how to find out the voltage regulator names
in Tx2 board and assign the values. Whether need to refer the Parker SOC TRM or Pin Mux excel sheet.
Please confirm.

-Thanks.

The power for the i2s1 is always on power you don’t need any regulator declare here.
