Subject: [PATCH v5 0/2] regulator: pf530x: NXP PF530x regulator driver

I wrote this driver to read settings and state from the nxp pf530x
regulator. Please consider it for inclusion, any criticism is welcome.

This revision (v5) adds a proper compatibility designation between devices
in the family, and fixes the devicetree schema to pass the dt_binding_check

Thanks,
Woodrow Douglass
