Other Parts Discussed in Thread: TPS659037, AM5728, PTPS659037
HI all:
Just now we use am5728evm to development software, the pmic is tps659037.
We know the pmic's devicetree is like below:
smps45_reg: smps45 {
/* VDD_DSPEVE, VDD_IVA, VDD_GPU */
regulator-name = "smps45";
regulator-min-microvolt = < 850000>;
regulator-max-microvolt = <1250000>;
regulator-always-on;
regulator-boot-on;
};
smps6_reg: smps6 {
/* VDD_CORE */
regulator-name = "smps6";
regulator-min-microvolt = <850000>;
regulator-max-microvolt = <1150000>;
regulator-always-on;
regulator-boot-on;
};
However we found anther pmic ptps659037, which is used by the am5728 idk.
His pmic's devicetree is like below
smps6_reg: smps6 {
/* VDD_GPU */
regulator-name = "smps6";
regulator-min-microvolt = <850000>;
regulator-max-microvolt = <1250000>;
regulator-always-on;
regulator-boot-on;
};
smps7_reg: smps7 {
/* VDD_CORE */
regulator-name = "smps7";
regulator-min-microvolt = <850000>;
regulator-max-microvolt = <1150000>;
regulator-always-on;
regulator-boot-on;
};
smps8_reg: smps8 {
/* 5728 - VDD_IVAHD */
/* 5718 - N.C. test point */
regulator-name = "smps8";
};
So we can know the two chip is different however we found their driver is same(driver/regulator/palmas-regulator.c)
So we are confusing about this
How the driver is compatible with this two pmic.
thanks
best regards
