[v3,1/7] dt-bindings: mfd: brcm,bcm59056: Convert to YAML

Commit Message

Artur Weber Jan. 31, 2025, 6:13 p.m. UTC

Convert devicetree bindings for the Broadcom BCM59056 PMU MFD from
TXT to YAML format. This patch does not change any functionality;
the bindings remain the same.

The bindings have been split into two parts: the MFD binding and
a separate binding for the regulator node, to simplify the addition
of other models later (which have different regulators).

Signed-off-by: Artur Weber <[e-mail]>

Changes in v3:
- Moved regulator node to separate binding
- Removed quotes around compatibles/vbus property
- Style fixes for example
