The following patch set adds support for clock gating
of the SNVS peripheral required on the Vybrid platform.
Also adds a device tree node for this peripheral.
This patchset was send before along with the patch which
had clock changes to the rtc-snvs driver. Since these could
not be merged then, till the changes for rtc-snvs landed in
the mainline, I am sending them anew as the changes are now
in the for-next branch
https://git.kernel.org/cgit/linux/kernel/git/shawnguo/linux.git/log/?h=for-next
The initial discussion can be found at the below links for the
earlier set of patches:

Add device tree node for the Secure Non-Volatile Storage
(SNVS) on the VF610 platform. The SNVS block also has a
Real Time Counter (RTC).
