Binding for Samsung S2M and S5M family clock generator block
============================================================
This is a part of device tree bindings for S2M and S5M family multi-function
devices.
More information can be found in bindings/mfd/sec-core.txt file.
The S2MPS11/13/15 and S5M8767 provide three(AP/CP/BT) buffered 32.768 kHz
outputs. The S2MPS14 provides two (AP/BT) buffered 32.768 KHz outputs.
To register these as clocks with common clock framework instantiate under
main device node a sub-node named "clocks".
It uses the common clock binding documented in:
- Documentation/devicetree/bindings/clock/clock-bindings.txt
Required properties of the "clocks" sub-node:
- #clock-cells: should be 1.
- compatible: Should be one of: "samsung,s2mps11-clk", "samsung,s2mps13-clk",
"samsung,s2mps14-clk", "samsung,s5m8767-clk"
The S2MPS15 uses the same compatible as S2MPS13, as both provides similar
clocks.
Each clock is assigned an identifier and client nodes use this identifier
to specify the clock which they consume.

* 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

* Samsung S2MPS11/13/14/15 and S2MPU02 Voltage and Current Regulator
The Samsung S2MPS11 is a multi-function device which includes voltage and
current regulators, RTC, charger controller and other sub-blocks. 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 one of the following
- "samsung,s2mps11-pmic"
- "samsung,s2mps13-pmic"
- "samsung,s2mps14-pmic"
- "samsung,s2mps15-pmic"
- "samsung,s2mpu02-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 s2mps11 are delivered to.
- interrupts: Interrupt specifiers for interrupt sources.
- samsung,s2mps11-wrstbi-ground: Indicates that WRSTBI pin of PMIC is pulled
down. When the system is suspended it will always go down thus triggerring
unwanted buck warm reset (setting buck voltages to default values).
- samsung,s2mps11-acokb-ground: Indicates that ACOKB pin of S2MPS11 PMIC is
connected to the ground so the PMIC must manually set PWRHOLD bit in CTRL1
register to turn off the power. Usually the ACOKB is pulled up to VBATT so
when PWRHOLD pin goes low, the rising ACOKB will trigger power off.
Optional nodes:
- clocks: s2mps11, s2mps13, s2mps15 and s5m8767 provide three(AP/CP/BT) buffered 32.768
KHz outputs, so to register these as clocks with common clock framework
instantiate a sub-node named "clocks". It uses the common clock binding
documented in :
[Documentation/devicetree/bindings/clock/clock-bindings.txt]
The s2mps14 provides two (AP/BT) buffered 32.768 KHz outputs.

- The following is the list of clocks generated by the controller. Each clock
is assigned an identifier and client nodes use this identifier to specify
the clock which they consume.

- compatible: Should be one of: "samsung,s2mps11-clk", "samsung,s2mps13-clk",
"samsung,s2mps14-clk", "samsung,s5m8767-clk"
The s2msp15 uses the same compatible as s2mps13, as both provides similar clocks.
- regulators: The regulators of s2mps11 that have to be instantiated should be
included in a sub-node named 'regulators'. Regulator nodes included in this
sub-node should be of the format as listed below.
regulator_name {
[standard regulator constraints....];
};
regulator-ramp-delay for BUCKs = [6250/12500/25000(default)/50000] uV/us
BUCK[2/3/4/6] supports disabling ramp delay on hardware, so explicitly
regulator-ramp-delay = <0> can be used for them to disable ramp delay.
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>.
Grouping of BUCKs sharing ramp rate setting is as follow : BUCK[1, 6],
BUCK[3, 4], and BUCK[7, 8, 10]
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>;
};
The regulator constraints inside the regulator nodes use the standard regulator
bindings which are documented elsewhere.
The following are the names of the regulators that the s2mps11 pmic block
supports. Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
as per the datasheet of s2mps11.
- LDOn
- valid values for n are:
- S2MPS11: 1 to 38
- S2MPS13: 1 to 40

property is specified, the 's5m8767,pmic-buck[2/3/4]-dvs-voltage'
property should specify atleast one voltage level (which would be a
safe operating voltage).
If either of the 's5m8767,pmic-buck[2/3/4]-uses-gpio-dvs' optional
property is specified, then all the eight voltage values for the
's5m8767,pmic-buck[2/3/4]-dvs-voltage' should be specified.
Optional properties:
- interrupt-parent: Specifies the phandle of the interrupt controller to which
the interrupts from s5m8767 are delivered to.

Regulators: The regulators of s5m8767 that have to be instantiated should be
included in a sub-node named 'regulators'. Regulator nodes included in this
sub-node should be of the format as listed below.
regulator_name {
ldo1_reg: LDO1 {
regulator-name = "VDD_ALIVE_1.0V";
regulator-min-microvolt = <1100000>;
regulator-max-microvolt = <1100000>;

Binding for Samsung S2MPA01 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 S2MPA01 device 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 S2MPA01 device:
- 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
Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
as per the datasheet of device.
Optional properties of buck regulator nodes under "regulators" sub-node:
- 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 the same
regulator-ramp-delay value for them.
Groups sharing ramp rate:
- buck{1,6},
- buck{2,4},
- buck{8,9,10}.
Example:
s2mpa01_pmic@66 {
