This adds a driver for the FAN53555 family of regulators and wraps it in a PMIC implementation. While these devices support a 'normal' and 'suspend' mode (controlled via an external pin) to switch between two programmable voltages, this incarnation of the driver assumes that the device is always operating in 'normal' mode. Only setting/reading the programmed voltage is supported at this time and the following device functionality remains unsupported: - switching the selected voltage (via a GPIO) - disabling the voltage output via software-control This matches the functionality of the Linux driver. Tested on a RK3399-Q7 (with 'option 5' devices): setting voltages from the U-Boot shell and verifying output voltages on the board.

device for each IC's interface. Then, each children uses its parent

for read/write. For detailed description, please refer to the files:
