[PATCH v4 1/5] dt-bindings: mfd: convert twl-family.txt to json-schema

From: Andreas Kemnade
Date: Sat Sep 16 2023 - 06:08:27 EST


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.

Texas Instruments TWL family (twl4030) pwrbutton module

This module is part of the TWL4030. For more details about the whole
-chip see Documentation/devicetree/bindings/mfd/twl-family.txt.
+chip see Documentation/devicetree/bindings/mfd/ti,twl.yaml.

This module provides a simple power button event via an Interrupt.

-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:
