* Samsung S2MPA01 Voltage and Current Regulator
The Samsung S2MPA01 is a multi-function device which includes high
efficiency buck converters including Dual-Phase buck converter, various LDOs,
and an RTC. It is interfaced to the host controller using an I2C interface.
Each sub-block is addressed by the host system using different I2C slave
addresses.
Required properties:
- compatible: Should be "samsung,s2mpa01-pmic".
- reg: Specifies the I2C slave address of the PMIC block. It should be 0x66.
Optional properties:
- interrupt-parent: Specifies the phandle of the interrupt controller to which
the interrupts from s2mpa01 are delivered to.
- interrupts: An interrupt specifier for the sole interrupt generated by the
device.
Optional nodes:
- regulators: The regulators of s2mpa01 that have to be instantiated should be
included in a sub-node named 'regulators'. Regulator nodes and constraints
included in this sub-node use the standard regulator bindings which are
documented elsewhere.
Properties for BUCK regulator nodes:
- regulator-ramp-delay: ramp delay in uV/us. May be 6250, 12500
(default), 25000, or 50000. May be 0 for disabling the ramp delay on
BUCK{1,2,3,4}.
In the absence of the regulator-ramp-delay property, the default ramp
delay will be used.
NOTE: Some BUCKs share the ramp rate setting i.e. same ramp value will be set
for a particular group of BUCKs. So provide same regulator-ramp-delay=<value>.
The following BUCKs share ramp settings:
* 1 and 6
* 2 and 4
* 8, 9, and 10
The following are the names of the regulators that the s2mpa01 PMIC block
supports. Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
as per the datasheet of s2mpa01.
- LDOn
- valid values for n are 1 to 26
- Example: LDO1, LD02, LDO26
- BUCKn
- valid values for n are 1 to 10.
- Example: BUCK1, BUCK2, BUCK9
Example:
s2mpa01_pmic@66 {
compatible = "samsung,s2mpa01-pmic";
reg = <0x66>;
regulators {
ldo1_reg: LDO1 {
regulator-name = "VDD_ALIVE";
regulator-min-microvolt = <1000000>;
regulator-max-microvolt = <1000000>;
};
ldo2_reg: LDO2 {
regulator-name = "VDDQ_MMC2";
regulator-min-microvolt = <2800000>;
regulator-max-microvolt = <2800000>;
regulator-always-on;
};
buck1_reg: BUCK1 {
regulator-name = "vdd_mif";
regulator-min-microvolt = <950000>;
regulator-max-microvolt = <1350000>;
regulator-always-on;
regulator-boot-on;
};
buck2_reg: BUCK2 {
regulator-name = "vdd_arm";
regulator-min-microvolt = <950000>;
regulator-max-microvolt = <1350000>;
regulator-always-on;
regulator-boot-on;
regulator-ramp-delay = <50000>;
};
