Subject: [PATCH v4 1/5] dt-bindings: mfd: convert twl-family.txt to json-schema
Convert the TWL[46]030 binding to DT schema format. To do it as a step by
step work, do not include / handle nodes for subdevices yet, just convert
things with minimal corrections. There are already some bindings for its
subdevices in the tree.

-The TWLs are Integrated Power Management Chips.
-Some version might contain much more analog function like
-USB transceiver or Audio amplifier.
-These chips are connected to an i2c bus.
-
-
-Required properties:
-- compatible : Must be "ti,twl4030";
- For Integrated power-management/audio CODEC device used in OMAP3
- based boards
-- compatible : Must be "ti,twl6030";
- For Integrated power-management used in OMAP4 based boards
-- interrupts : This i2c device has an IRQ line connected to the main SoC
-- interrupt-controller : Since the twl support several interrupts internally,
- it is considered as an interrupt controller cascaded to the SoC one.
-- #interrupt-cells = <1>;
-
-Optional node:
-- Child nodes contain in the twl. The twl family is made of several variants
- that support a different number of features.
- The children nodes will thus depend of the capability of the variant.
-
-
-Example:
-/*
- * Integrated Power Management Chip
- * https://www.ti.com/lit/ds/symlink/twl6030.pdf
- */
