I wrote this driver to read settings and state from the nxp pf530x
regulator. Please consider it for inclusion, any criticism is welcome.
Upon re-reviewing the dt binding, I realized I should have referenced
regulator.yaml, so here's v6.
Thanks,
Woodrow Douglass

Changes in v6:
- Make sure that the device tree binding properly references regulator.yaml
- Link to v5: https://lore.kernel.org/r/20250902-pf530x-v5-0-658c403e6a52@carnegierobotics.com
Changes in v5:
- Fixed compatibility match to properly fall back to pf5300
- Reordered patches so that devicetree schema comes before the driver itself
- Modified nxp,pf5300 schema to pass `make dt_binding_check`
- Link to v4: https://lore.kernel.org/r/20250902-pf530x-v4-0-4727f112424e@carnegierobotics.com

- Replaced pf530x_is_enabled function with regulator_is_enabled_regmap
- Added status bits from INT_SENSE1 to pf530x_get_status function
