regulator: Switch i2c drivers back to use .probe() After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

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.

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.
