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.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

dtschema/dtc warnings/errors:
Documentation/devicetree/bindings/mfd/ti,twl.example.dtb: /example-0/i2c/pmic@48/rtc: failed to match any schema with compatible: ['ti,twl4030-rtc']

doc reference errors (make refcheckdocs):
Documentation/devicetree/bindings/input/twl4030-pwrbutton.txt: Documentation/devicetree/bindings/mfd/twl-family.txt

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20230830182038.878265-2-andreas@kemnade.info

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

No, this must be false. example-schema and all device bindings require
this to be false. Having it true makes the schema basically no-op, so
why do you need it?

-Texas Instruments TWL family

-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
