[PATCH 0/3] Add new binding regulator-fixed-clock to regulator-fixed
From: Philippe Schenker

Our hardware has a FET that is switching power rail of the ethernet PHY
on and off. This switching enable signal is a clock from the SoC.
There is no possibility in regulator subsystem to have this hardware
reflected in software.
I already discussed with Mark Brown about possible solutions and he
suggested to create at least a new compatible. 
This discussion includes also a better explanation of our circuit as
well as schematics. So please refer to that link if you have questions
In this first attempt I created a new binding "regulator-fixed-clock"
that can take a clock from devicetree. This is a simple addition to
regulator-fixed. If the binding regulator-fixed-clock is given, the
clock is simply enabled on regulator enable and disabled on regulator
To be able to have multiple consumers a counter variable is also given
that tells how many consumers need power from this regulator.
Philippe Schenker (3):
regulator: fixed: add possibility to enable by clock
ARM: dts: imx6ull-colibri: add phy-supply and respective regulator
dt-bindings: regulator: add regulator-fixed-clock binding
