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.
|
||||
Clock ID Devices
|
||||
----------------------------------------------------------
|
||||
32KhzAP 0 S2MPS11/13/14/15, S5M8767
|
||||
32KhzCP 1 S2MPS11/13/15, S5M8767
|
||||
32KhzBT 2 S2MPS11/13/14/15, S5M8767
|
||||
|
||||
Include dt-bindings/clock/samsung,s2mps11.h file to use preprocessor defines
|
||||
in device tree sources.
|
||||
|
||||
|
||||
Example:
|
||||
|
||||
s2mps11_pmic@66 {
|
||||
compatible = "samsung,s2mps11-pmic";
|
||||
reg = <0x66>;
|
||||
|
||||
s2m_osc: clocks {
|
||||
compatible = "samsung,s2mps11-clk";
|
||||
#clock-cells = <1>;
|
||||
clock-output-names = "xx", "yy", "zz";
|
||||
};
|
||||
};

Binding for Samsung S2M and S5M family multi-function device
|
||||
============================================================
|
||||
|
||||
This is a part of device tree bindings for S2M and S5M family multi-function
|
||||
devices.
|
||||
|
||||
The Samsung S2MPA01, S2MPS11/13/14/15, S2MPU02 and S5M8767 is a family
|
||||
of multi-function devices which include voltage and current regulators, RTC,
|
||||
charger controller, clock outputs and other sub-blocks. It is interfaced
|
||||
to the host controller using an I2C interface. Each sub-block is usually
|
||||
addressed by the host system using different I2C slave addresses.
|
||||
|
||||
|
||||
This document describes bindings for main device node. Optional sub-blocks
|
||||
must be a sub-nodes to it. Bindings for them can be found in:
|
||||
- bindings/regulator/samsung,s2mpa01.txt
|
||||
- bindings/regulator/samsung,s2mps11.txt
|
||||
- bindings/regulator/samsung,s5m8767.txt
|
||||
- bindings/clock/samsung,s2mps11.txt
|
||||
|
||||
|
||||
Required properties:
|
||||
- compatible: Should be one of the following
|
||||
- "samsung,s2mpa01-pmic",
|
||||
- "samsung,s2mps11-pmic",
|
||||
- "samsung,s2mps13-pmic",
|
||||
- "samsung,s2mps14-pmic",
|
||||
- "samsung,s2mps15-pmic",
|
||||
- "samsung,s2mpu02-pmic",
|
||||
- "samsung,s5m8767-pmic".
|
||||
- reg: Specifies the I2C slave address of the pmic block. It should be 0x66.
|
||||
|
||||
Optional properties:
|
||||
- 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.
|
||||
|
||||

|
||||

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}.

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>;
|
||||
};
|
||||
|

||||
compatible = "samsung,s2mps11-pmic";
|
||||
reg = <0x66>;
