mfd: Add MAX8907 core driver The MAX8907 is an I2C-based power-management IC containing voltage regulators, a reset controller, a real-time clock, and a touch-screen controller. The original driver was written by: * Gyungoh Yoo <jack.yoo@maxim-ic.com> Various fixes and enhancements by: * Jin Park <jinyoungp@nvidia.com> * Tom Cherry <tcherry@nvidia.com> * Prashant Gaikwad <pgaikwad@nvidia.com> * Dan Willemsen <dwillemsen@nvidia.com> * Laxman Dewangan <ldewangan@nvidia.com> During upstreaming, I (swarren): * Converted to regmap. * Converted to regmap-irq. * Allowed probing from device tree. * Renamed from max8907c->max8907, since the driver covers at least the C and B revisions. * General cleanup.

MAX8907 regulator
Required properties:
- compatible: "maxim,max8907"
- reg: I2C slave address
- interrupts: The interrupt output of the controller
- mbatt-supply: The input supply for MBATT, BBAT, SDBY, VRTC.
- in-v1-supply: The input supply for SD1.
- in-v2-supply: The input supply for SD2.
- in-v3-supply: The input supply for SD3.
- in1-supply: The input supply for LDO1.
...
- in20-supply: The input supply for LDO20.
- regulators: A node that houses a sub-node for each regulator within the
device. Each sub-node is identified using the regulator-compatible
property, with valid values listed below. The content of each sub-node
is defined by the standard binding for regulators; see regulator.txt.
mfd: max8907: Add power off control Add DT property "maxim,system-power-controller" to indicate whether the PMIC is in charge of controlling the system power. If this is set, the driver will provide the pm_power_off() function. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

Optional properties:
- maxim,system-power-controller: Boolean property indicating that the PMIC
controls the overall system power.

Valid regulator-compatible values are:
sd1, sd2, sd3, ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7, ldo8, ldo9, ldo10,
ldo11, ldo12, ldo13, ldo14, ldo15, ldo16, ldo17, ldo18, ldo19, ldo20, out5v,

compatible = "maxim,max8907";
reg = <0x3c>;
interrupts = <0 86 0x4>;
