dt-bindings: regulator/mfd: Reorganize S2MPA01 bindings
The mfd/s2mpa01.txt duplicates some of the information about bindings with old mfd/s2mps11.txt. Now common part exists entirely in mfd/samsung,sec-core.txt so: - add company prefix to file name (regulator/samsung,s2mpa01.txt), - remove duplicated information, - reorganize the contents to match style of regulator/samsung,s2mps11.txt.

-* 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-always-on;

- regulator-ramp-delay = <50000>;
- };
