Binding for Samsung S2M family regulator block
==============================================
This is a part of device tree bindings for S2M family multi-function devices.
More information can be found in bindings/mfd/sec-core.txt file.
The S2MPS11/13/14/15 and S2MPU02 devices provide buck and LDO regulators.
To register these with regulator framework instantiate under main device node
a sub-node named "regulators" with more sub-nodes for each regulator using the
common regulator binding documented in:
- Documentation/devicetree/bindings/regulator/regulator.txt
Names of regulators supported by different devices:
- LDOn
- valid values for n are:
- S2MPS11: 1 to 38
- S2MPS13: 1 to 40
- S2MPS14: 1 to 25
- S2MPS15: 1 to 27
- S2MPU02: 1 to 28
- Example: LDO1, LDO2, LDO28
- BUCKn
- valid values for n are:
- S2MPS11: 1 to 10
- S2MPS13: 1 to 10
- S2MPS14: 1 to 5
- S2MPS15: 1 to 10
- S2MPU02: 1 to 7
- Example: BUCK1, BUCK2, BUCK9
Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
as per the datasheet of device.
Optional properties of the nodes under "regulators" sub-node:
- regulator-ramp-delay: ramp delay in uV/us. May be 6250, 12500,
25000 (default) or 50000.
Additionally S2MPS11 supports disabling ramp delay for BUCK{2,3,4,6}
by setting it to <0>.
Note: On S2MPS11 some bucks share the ramp rate setting i.e. same ramp value
will be set for a particular group of bucks so provide the same
regulator-ramp-delay value for them.
Groups sharing ramp rate:
- buck{1,6},
- buck{3,4},
- buck{7,8,10}.
- samsung,ext-control-gpios: On S2MPS14 the LDO10, LDO11 and LDO12 can be
configured to external control over GPIO. To turn this feature on this
property must be added to the regulator sub-node:
- samsung,ext-control-gpios: GPIO specifier for one GPIO
controlling this regulator (enable/disable)
Example:
LDO12 {
regulator-name = "V_EMMC_2.8V";
regulator-min-microvolt = <2800000>;
regulator-max-microvolt = <2800000>;
samsung,ext-control-gpios = <&gpk0 2 0>;
};
Example:
s2mps11_pmic@66 {
compatible = "samsung,s2mps11-pmic";
reg = <0x66>;
regulators {
ldo1_reg: LDO1 {
regulator-name = "VDD_ABB_3.3V";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
};
ldo2_reg: LDO2 {
regulator-name = "VDD_ALIVE_1.1V";
regulator-min-microvolt = <1100000>;
regulator-max-microvolt = <1100000>;
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>;
};
};
};
