Commit Message

Prashant Gaikwad Jan. 11, 2013, 7:46 a.m. UTC
Migrate tegra clock support to drivers/clk/tegra, this involves
moving
1. definition of tegra_cpu_car_ops to clk.c
2. definition of reset functions to clk-peripheral.c
3. change parent of cpu clock.
4. Remove legacy clock initialization.
5. Initialize clocks using DT.
6. Remove all instance of mach/clk.h
