Subject: [PATCH] dt-bindings: mfd: Convert rn5t618 to json-schema
Convert the RN5T618 binding to DT schema format. Also
clearly state which regulators are available.
Signed-off-by: Andreas Kemnade <andreas@...nade.info>

I have noted myself here as maintainer because I wrote most of the
code of the several subdevices, although not of the .txt-binding.
Due to its .txt-format history BSD license was not added.
I happily ignored the "does MAINTAINERS need updating" thing
from checkpatch.pl, I do not know whether that PMIC should
have a separate entry there.

+ The RN5T618/RC5T619 provides additionally a Li-ion battery charger,
+ fuel gauge, and an ADC.
+ The RC5T619 additionnally includes USB charger detection and an RTC.

-* Ricoh RN5T567/RN5T618 PMIC
-
-Ricoh RN5T567/RN5T618/RC5T619 is a power management IC family which
-integrates 3 to 5 step-down DCDC converters, 7 to 10 low-dropout regulators,
-GPIOs, and a watchdog timer. It can be controlled through an I2C interface.
-The RN5T618/RC5T619 provides additionally a Li-ion battery charger,
-fuel gauge, and an ADC.
-The RC5T619 additionnally includes USB charger detection and an RTC.
-
-Required properties:
- - compatible: must be one of
- "ricoh,rn5t567"
- "ricoh,rn5t618"
- "ricoh,rc5t619"
- - reg: the I2C slave address of the device
-
-Optional properties:
- - interrupts: interrupt mapping for IRQ
- See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
- - system-power-controller:
- See Documentation/devicetree/bindings/power/power-controller.txt
-
-Sub-nodes:
- - regulators: the node is required if the regulator functionality is
- needed. The valid regulator names are: DCDC1, DCDC2, DCDC3, DCDC4
- (RN5T567/RC5T619), LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7, LDO8,
- LDO9, LDO10, LDORTC1 and LDORTC2.
- LDO7-10 are specific to RC5T619.
- The common bindings for each individual regulator can be found in:
- Documentation/devicetree/bindings/regulator/regulator.txt
-
-Example:
-
- pmic@32 {
- compatible = "ricoh,rn5t618";
- reg = <0x32>;
- interrupt-parent = <&gpio5>;
- interrupts = <11 IRQ_TYPE_EDGE_FALLING>;
- system-power-controller;
-
- regulators {
- DCDC1 {
- regulator-min-microvolt = <1050000>;
- regulator-max-microvolt = <1050000>;
- };
-
- DCDC2 {
- regulator-min-microvolt = <1175000>;
- regulator-max-microvolt = <1175000>;
- };
- };
- };
