[PATCH v2] dt-bindings: power: mfd: max8925: Convert to DT schema format

From: Sebastian Reichel
Date: Fri Sep 22 2023 - 19:32:01 EST

Convert the binding to DT schema format.

The sub-functions of this MFD device do not have their own compatible
string and are thus described directly in the MFD binding document
after being converted to YAML.

Hi,

I forgot to send a new version of this. max8925_battery is the last
non-YAML binding in power/supply/*, so let's get rid of it :)

@Lee, I put you in as maintainer, since the original people working on
max8925 long vanished and you are the maintainer of MFD (and backlight).
Please tell me if you have a better suggestion. Also I expect this will
go through your tree once it got ACK'd by the DT people and I don't need
an immutable branch.

Changes since PATCHv1:
* https://lore.kernel.org/all/20210413153407.GA1707829@xxxxxxxxxxxxxxxxxx/
* Update License to GPL OR BSD
* Add missing type references pointed out by Rob

-Required parent device properties:

-- reg : the I2C slave address for the max8925 chip
-- interrupts : IRQ line for the max8925 chip
-- interrupt-controller: describes the max8925 as an interrupt
- controller (has its own domain)
-- #interrupt-cells : should be 1.
