Subject: [PATCH v3 01/12] dt-bindings: clock: google,gs101-clock: add PERIC0 clock management unit
Add dt-schema documentation for the Connectivity Peripheral 0 (PERIC0)
clock management unit.

v3:
- rename the clock names to just "bus" and "ip" as per Rob's suggestion
- collect Peter's R-b tag
v2:
- fix comments as per Sam's suggestion and collect his R-b tag
- Rob's suggestion of renaming the clock-names to just "bus" and "ip"
was not implemented as I felt it affects readability in the driver
and consistency with other exynos clock drivers. I will happily update
the names in the -rc phase if someone else has a stronger opinion than
mine.
