[V2,0/2] clk: imx: scu: add parsing clocks from device tree support

This is a follow up of the patch thread.
https://www.spinics.net/lists/devicetree/msg283675.html

This patch series is a preparation for the MX8 Architecture improvement.
As for IMX SCU based platforms like MX8QM and MX8QXP, they are comprised
of a couple of SS(Subsystems) while most of them within the same SS
can be shared. e.g. Clocks, Devices and etc.

However, current device tree is heavily depends on Clocks IDs defined which
cause some troubles in writing the common <soc>-ss-xx.dtsi file.

This patch series adds a new binding to support parsing clocks from device tree
which can fully decouple the dependency of Clock IDs in device tree and make
us be able to write a fully generic clock driver for SCU based SoCs.
And it can make the driver much easily to be maintained in the future and
avoid writing a lot of duplicated codes.

ChangeLog:
v1->v2:
 * SCU clock changed to one cell clock binding inspired by arm,scpi.txt
   Documentation/devicetree/bindings/arm/arm,scpi.txt
 * Add required power domain property
 * Dropped PATCH 3&4 first, will send the updated version accordingly
   after the binding is finally determined,

  dt-bindings: clock: imx-lpcg: add support to parse clocks from device
    tree

Hi Rob,

Do you have a chance to help look at this?
