Subject: [PATCH v2] ARM: dts: twl6032: Add DTS file for TWL6032 PMIC

From: Mithil Bavishi <bavishimithil@...il.com>

Add a dedicated DTS file for the TWL6032 PMIC (Phoenix Lite). Already
has driver support with TWL6030 (Phoenix) since both of them are so
similar, some nodes can be reused from TWL6030 as well.

This can be included in the board files like twl6030.
Example:
...
&i2c1 {
    twl: twl@48 {
        reg = <0x48>;
        interrupts = <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>;
        interrupt-controller;
        interrupt-parent = <&gic>;
    };
};

/include/ "twl6032.dtsi"
...

Used in devices like samsung-espresso, amazon-jem, epson-embt2ws etc.

Changelog v2:
- Added nodes for pwm, pwm-led
- Added nodes for regulators - ldoln and ldo2
- Renamed nodes to match compatible names
- Removed regulator properties and voltages, since we do not have a datasheet and relying on downstream values is not always correct, hence let the properties and min/max volatages be defined in the board device trees.
