Subject: [U-Boot] [U-Boot,v5,1/3] power: add FAN53555 family support
Date: Mon, 10 Dec 2018 01:01:54 +0100 [thread overview]
Message-ID: <E1gW91G-0005HS-Rz@mail.theobroma-systems.com> (raw)
In-Reply-To: <1543604410-42192-1-git-send-email-philipp.tomsich@theobroma-systems.com>
> 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.

> Changes in v5:
> - introduced a PMIC (as requested by SJG) to wrap the single regulator
>
> Changes in v4:
> - fix issues introduced when updating for review comments (sorry for
> this: my submit-branch had diverged from the WIP-branch I used for
> testing and I didn't notice)
>
> Changes in v3:
> - update for review comments
>
> Changes in v2:
> - adapted documentation on the device-tree binding from Linux

Applied to u-boot-rockchip, thanks!
