};
[*] refer Documentation/devicetree/bindings/regulator/regulator.txt

This is a part of device tree bindings for Maxim MAX77802 Power Management
Integrated Circuit (PMIC).
The Maxim MAX77802 is a Power Management IC which includes voltage and
current regulators (10 high efficiency Buck regulators and 32 Low-DropOut

The MAX77802 provides two 32.768khz clock outputs that can be controlled
(gated/ungated) over I2C. The clock IDs are defined as preprocessor macros

Binding for Maxim MAX77802 regulators
This is a part of device tree bindings of MAX77802 multi-function device.
More information can be found in bindings/mfd/max77802.txt file.
The MAX77802 PMIC has 10 high-efficiency Buck and 32 Low-dropout (LDO)
regulators that can be controlled over I2C.
Following properties should be present in main device node of the MFD chip.
Optional properties:
- inb1-supply: The input supply for BUCK1
- inb2-supply: The input supply for BUCK2
- inb3-supply: The input supply for BUCK3
- inb4-supply: The input supply for BUCK4
- inb5-supply: The input supply for BUCK5
- inb6-supply: The input supply for BUCK6
- inb7-supply: The input supply for BUCK7
- inb8-supply: The input supply for BUCK8
- inb9-supply: The input supply for BUCK9
- inb10-supply: The input supply for BUCK10
- inl1-supply: The input supply for LDO8 and LDO15
- inl2-supply: The input supply for LDO17, LDO27, LDO30 and LDO35
- inl3-supply: The input supply for LDO3, LDO5, LDO6 and LDO7
- inl4-supply: The input supply for LDO10, LDO11, LDO13 and LDO14
- inl5-supply: The input supply for LDO9 and LDO19
- inl6-supply: The input supply for LDO4, LDO21, LDO24 and LDO33
- inl7-supply: The input supply for LDO18, LDO20, LDO28 and LDO29
- inl9-supply: The input supply for LDO12, LDO23, LDO25, LDO26, LDO32 and LDO34
- inl10-supply: The input supply for LDO1 and LDO2
Optional nodes:
- regulators : The regulators of max77802 have to be instantiated
under subnode named "regulators" using the following format.
regulator-name {
standard regulator constraints....
};
refer Documentation/devicetree/bindings/regulator/regulator.txt
The regulator node name should be initialized with a string to get matched
with their hardware counterparts as follow. The valid names are:
-LDOn : for LDOs, where n can lie in ranges 1-15, 17-21, 23-30
and 32-35.
example: LDO1, LDO2, LDO35.
-BUCKn : for BUCKs, where n can lie in range 1 to 10.
example: BUCK1, BUCK5, BUCK10.
The max77802 regulator supports two different operating modes: Normal and Low
Power Mode. Some regulators support the modes to be changed at startup or by
the consumers during normal operation while others only support to change the
mode during system suspend. The standard regulator suspend states binding can
be used to configure the regulator operating mode.
The regulators that support the standard "regulator-initial-mode" property,
changing their mode during normal operation are: LDOs 1, 3, 20 and 21.
The possible values for "regulator-initial-mode" and "regulator-mode" are:
1: Normal regulator voltage output mode.
3: Low Power which reduces the quiescent current down to only 1uA
The valid modes list is defined in the dt-bindings/regulator/maxim,max77802.h
header and can be included by device tree source files.
The standard "regulator-mode" property can only be used for regulators that
support changing their mode to Low Power Mode during suspend. These regulators
are: BUCKs 2-4 and LDOs 1-35. Also, it only takes effect if the regulator has
been enabled for the given suspend state using "regulator-on-in-suspend" and
has not been disabled for that state using "regulator-off-in-suspend".
Example:
max77802@9 {
compatible = "maxim,max77802";
interrupt-parent = <&wakeup_eint>;
interrupts = <26 0>;
reg = <0x09>;
#address-cells = <1>;

This is a part of device tree bindings for Maxim MAX77802 Power Management
Integrated Circuit (PMIC).
The Maxim MAX77686 provides 10 high-efficiency Buck and 32 Low-DropOut (LDO)
regulators.
See also Documentation/devicetree/bindings/mfd/maxim,max77802.yaml for
additional information and example.
Certain regulators support "regulator-initial-mode" and "regulator-mode".
The valid modes list is defined in the dt-bindings/regulator/maxim,max77802.h
and their meaning is::
1 - Normal regulator voltage output mode.
3 - Low Power which reduces the quiescent current down to only 1uA
The standard "regulator-mode" property can only be used for regulators that
support changing their mode to Low Power Mode during suspend. These
regulators are:: bucks 2-4 and LDOs 1-35. Also, it only takes effect if the
regulator has been enabled for the given suspend state using
"regulator-on-in-suspend" and has not been disabled for that state using
"regulator-off-in-suspend".

* Samsung SPI Controller
The Samsung SPI controller is used to interface with various devices such as flash
and display controllers using the SPI communication interface.
Required SoC Specific Properties:
- compatible: should be one of the following.
- samsung,s3c2443-spi: for s3c2443, s3c2416 and s3c2450 platforms
- samsung,s3c6410-spi: for s3c6410 platforms
- samsung,s5pv210-spi: for s5pv210 and s5pc110 platforms
- samsung,exynos5433-spi: for exynos5433 compatible controllers
- samsung,exynos7-spi: for exynos7 platforms <DEPRECATED>
- reg: physical base address of the controller and length of memory mapped
region.
- interrupts: The interrupt number to the cpu. The interrupt specifier format
depends on the interrupt controller.
- dmas : Two or more DMA channel specifiers following the convention outlined
in bindings/dma/dma.txt
- dma-names: Names for the dma channels. There must be at least one channel
named "tx" for transmit and named "rx" for receive.
- clocks: specifies the clock IDs provided to the SPI controller; they are
required for interacting with the controller itself, for synchronizing the bus
and as I/O clock (the latter is required by exynos5433 and exynos7).
- clock-names: string names of the clocks in the 'clocks' property; for all the
the devices the names must be "spi", "spi_busclkN" (where N is determined by
"samsung,spi-src-clk"), while Exynos5433 should specify a third clock
"spi_ioclk" for the I/O clock.
Required Board Specific Properties:
- #address-cells: should be 1.
- #size-cells: should be 0.
Optional Board Specific Properties:
- samsung,spi-src-clk: If the spi controller includes a internal clock mux to
select the clock source for the spi bus clock, this property can be used to
indicate the clock to be used for driving the spi bus clock. If not specified,
the clock number 0 is used as default.
- num-cs: Specifies the number of chip select lines supported. If
not specified, the default number of chip select lines is set to 1.
- cs-gpios: should specify GPIOs used for chipselects (see spi-bus.txt)
- no-cs-readback: the CS line is disconnected, therefore the device should not
operate based on CS signalling.
SPI Controller specific data in SPI slave nodes:
- The spi slave nodes should provide the following information which is required
by the spi controller.
- samsung,spi-feedback-delay: The sampling phase shift to be applied on the
miso line (to account for any lag in the miso line). The following are the
valid values.
- 0: No phase shift.
- 1: 90 degree phase shift sampling.
- 2: 180 degree phase shift sampling.
- 3: 270 degree phase shift sampling.
Aliases:
- All the SPI controller nodes should be represented in the aliases node using
the following format 'spi{n}' where n is a unique number for the alias.
Example:
- SoC Specific Portion:
spi_0: spi@12d20000 {
compatible = "samsung,exynos4210-spi";
reg = <0x12d20000 0x100>;
interrupts = <0 66 0>;
dmas = <&pdma0 5
&pdma0 4>;
dma-names = "tx", "rx";
#address-cells = <1>;
#size-cells = <0>;
};
- Board Specific Portion:
spi_0: spi@12d20000 {
#address-cells = <1>;
#size-cells = <0>;
pinctrl-names = "default";
pinctrl-0 = <&spi0_bus>;
cs-gpios = <&gpa2 5 0>;
w25q80bw@0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "w25x80";
reg = <0>;
spi-max-frequency = <10000>;
controller-data {
samsung,spi-feedback-delay = <0>;
};
partition@0 {
label = "U-Boot";
reg = <0x0 0x40000>;
read-only;
};
partition@40000 {
label = "Kernel";
reg = <0x40000 0xc0000>;
};
};
};
