Krzysztof Kozlowski	6963569103	regulator: richtek,rt4801: parse GPIOs per regulator ... Having one enable-gpios property for all regulators is discouraged and instead, similarly to regulator core ena_gpiod feature, each GPIO should be present in each regulator node. Add support for parsing such GPIOs, keeping backwards compatibility.

ChiYuan Huang	5bbbfc7f7f	regulator: rt4801: Add support for RT4801 Display Bias regulator driver ... Adds support for the RT4801 DSV. It has two regulators (DSVP/DSVN) with an I2C interface. DSVP/DSVN can provide the display panel module for the positive/negative voltage range from (+/-)4V to (+/-)6V.
