Commit Message

Jun Nie April 27, 2015, 8:50 a.m. UTC
It adds a clock driver for zx296702 SoC to register the clock tree to
Common Clock Framework.  All the clocks of bus topology and some the
peripheral clocks are ready with this commit. Some missing leaf clocks
for peripherals will be added later when needed.
