From: Alina Yu
Date: Wed Aug 02 2023 - 23:51:23 EST

This patch series adds support for RTQ2208 SubPMIC regulators.
The RTQ2208 is a multi-phase, programmable power management IC that
integrate with dual multi-configurable, synchronous buck converters
and two ldos. The bucks features wide output voltage range from 0.4V to 2.05V
and the capability to configure the corresponding power stages.

Thank you,
