[PATCH v4 2/9] dt-bindings: mfd: brcm,bcm59056: Add compatible for BCM59054

From: Artur Weber <aweber.kernel@gmail.com>
Date: 2025-02-15 09:39:50
Also in: linux-devicetree, lkml
Subsystem: multifunction devices (mfd), open firmware and flattened device tree bindings, the rest, voltage and current regulator framework · Maintainers: Lee Jones, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds, Liam Girdwood, Mark Brown

The BCM59054 MFD is fairly similar to the BCM59056, and will use
the same driver. Add compatible and specify the allowed regulator
nodes.

Changes in v4:
- Fix yamllint errors (missing unevaluatedProperties)
- Drop comment with regulator name list
- Use full schema paths for $reg
- Change description of regulator binding to mention BCM59054
  explicitly
- Drop quotes around vbus reg name
- Change "Power Management IC" to "Power Management Unit" to match
  official Broadcom naming

Note that I did not end up moving the regulator refs from
allOf compatible matches; I explained my reasoning in [1].

Changes in v3:
- Split regulator node into separate file
- Removed quotes around compatible
