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 Tree Bindings Staging Area ================================= This directory contains device tree bindings for U-Boot. These follow along with Linux kernel bindings, with a few additions. By adding the files here, U-Boot patches can clearly show thees additions. This makes it easier for device tree people to review these additions in patches sent to the U-Boot mailing list. The intent IS to commit these files to U-Boot. Hopefully at some point the files will be stored in another repo (shared with Linux) which is brought in as needed. Changes here are intended to mirror changes in the Linux Documentation/devicetree/bindings/ directory. sjg@chromium.org 17-Jan-12
