[PATCH v6 0/2] Add Richtek RTQ2208 SubPMIC support

[Alina Yu]

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,
Alina yu
