Hi,
Using the above mentioned PMIC with my AM5728. Trying to configure SMPS 7 & 9 with the device tree as follows.
*****************************************************
smps7_reg: smps7 {
/* VDD_1V8 */
regulator-name = "smps7";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
regulator-always-on;
regulator-boot-on;
};
smps9_reg: smps9 {
/* VDD_1V8 */
regulator-name = "smps9";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
regulator-always-on;
regulator-boot-on;
};
******************************************************
The board doesn't boot up and the kernel log is as follows..

Are there any more things to be additionally done apart from configuring it in device tree?
