Add support for Richtek RT6190 36V 4-wwtich regulator
Subsystems (2)
v2 cover Add support for Richtek RT6190 36V 4-wwtich regulator
From: ChiYuan Huang <[email protected]>
The RT6190 is a 4-switch Buck-Boost controller designed for USB power delivery (USB PD). It operates with wide input voltage range from 4.5V to 36V, and the output voltage can be programmable between 3V and 36V. It implements peak current mode control mechanism to deliver up to 100W power with the programmable constant voltage and constant current output. It also has built-in charge pumps for driving external low-cost N-MOSFETs to control the power path.
Since v2:
- Rename binding filename to 'richtek,rt6190.yaml'

It's coming from gpio-consumer-common.yaml. If so, does it still need to declare the 'maxItems'?
