Hi,
Changes since v1 (sent by Tero):
- Rebased on linux-next
- Split the dts and binding document patch
- Tested it on omap5-uevm that the HPPLL of twl6040 is working (xtal clock is
suplied)
The v1 of this series was sent about two years ago:
http://linux-arm-kernel.infradead.narkive.com/hBBbM4D7/patch-0-5-arm-omap5-add-support-for-fref-xtal-clk
but for some reason it was not applied back then, but I have been rolling it on
top of linux-next ever since.
Regards,
Peter

Control module can have multiple instances in a system, each with separate
address space and features. Add base support for these auxiliary instances,
with support for syscon and clock mappings under them.
