Merge branch 'sti_drivers'
Peter Griffin says:
====================
Fix sti drivers whcih mix reg address spaces
A V2 of this old series incorporating Arnd and Lees Feedback form v1.
Following on from Arnds comments about the picophy driver here
https://lkml.org/lkml/2014/11/13/161, this series fixes the
remaining upstreamed drivers for STI, which are mixing address spaces
in the reg property. We do this in a way similar to the keystone
and bcm7445 platforms, by having sysconfig phandle/ offset pair
(where only one register is required). Or phandle / integer array
where multiple offsets in the same bank are needed).
This series breaks DT compatability! But the platform support
is WIP and only being used by the few developers who are upstreaming
support for it. I've made each change to the driver / dt doc / dt
file as a single atomic commit so the kernel will remain bisectable.
This series then also enables the picophy driver, and adds back in
the ehci/ohci dt nodes for stih410 which make use of the picophy.
