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 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.
|

a sub-node named "regulators" with more sub-nodes for each regulator using the

common regulator binding documented in:

|

|

|

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

- Example: BUCK1, BUCK2, BUCK9
|

Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number

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-min-microvolt = <2800000>;

Binding for Samsung S5M8767 regulator block
|
||||
===========================================
|
||||
|
||||
This is a part of device tree bindings for S5M family multi-function devices.
|
||||
More information can be found in bindings/mfd/sec-core.txt file.
|
||||
|
||||
The S5M8767 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
|
||||
|
||||
|
||||
Required properties of the main device node (the parent!):
|
||||
- s5m8767,pmic-buck2-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
|
||||
units for buck2 when changing voltage using gpio dvs. Refer to [1] below
|
||||
for additional information.
|
||||
|
||||
- s5m8767,pmic-buck3-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
|
||||
units for buck3 when changing voltage using gpio dvs. Refer to [1] below
|
||||
for additional information.
|
||||
|
||||
- s5m8767,pmic-buck4-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
|
||||
units for buck4 when changing voltage using gpio dvs. Refer to [1] below
|
||||
for additional information.
|
||||
|
||||
- s5m8767,pmic-buck-ds-gpios: GPIO specifiers for three host gpio's used
|
||||
for selecting GPIO DVS lines. It is one-to-one mapped to dvs gpio lines.
|
||||
|
||||
[1] If none of the 's5m8767,pmic-buck[2/3/4]-uses-gpio-dvs' optional
|
||||
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 of the main device node (the parent!):
|
||||
- s5m8767,pmic-buck2-uses-gpio-dvs: 'buck2' can be controlled by gpio dvs.
|
||||
- s5m8767,pmic-buck3-uses-gpio-dvs: 'buck3' can be controlled by gpio dvs.
|
||||
- s5m8767,pmic-buck4-uses-gpio-dvs: 'buck4' can be controlled by gpio dvs.
|
||||
|
||||
Additional properties required if either of the optional properties are used:
|
||||
|
||||
- s5m8767,pmic-buck234-default-dvs-idx: Default voltage setting selected from
|
||||
the possible 8 options selectable by the dvs gpios. The value of this
|
||||
property should be between 0 and 7. If not specified or if out of range, the
|
||||
default value of this property is set to 0.
|
||||
|
||||
- s5m8767,pmic-buck-dvs-gpios: GPIO specifiers for three host gpio's used
|
||||
for dvs. The format of the gpio specifier depends in the gpio controller.
|
||||
|
||||
|
||||
Names of regulators supported by S5M8767 device:
|
||||
- LDOn
|
||||
- valid values for n are 1 to 28
|
||||
- Example: LDO1, LDO2, LDO28
|
||||
- BUCKn
|
||||
- valid values for n are 1 to 9.
|
||||
- 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:
|
||||
- op_mode: describes the different operating modes of the LDO's with
|
||||
power mode change in SOC. The different possible values are,
|
||||
0 - always off mode
|
||||
1 - on in normal mode
|
||||
2 - low power mode
|
||||
3 - suspend mode
|
||||
- s5m8767,pmic-ext-control-gpios: (optional) GPIO specifier for one
|
||||
GPIO controlling this regulator
|
||||
(enable/disable); This is valid only
|
||||
for buck9.
|
||||
|
||||
