[PATCH V2 2/2] ARM: dra7xx: Fix counter frequency drift for AM572x errata i856.

2014-12-16 Thread Lennart Sorensen
Errata i856 for the AM572x (DRA7xx) points out that the 32.768KHz external crystal is not enabled at power up. Instead the CPU falls back to using an emulation for the 32KHz clock which is SYSCLK1/610. SYSCLK1 is usually 20MHz on boards so far (which gives an emulated frequency of 32.786KHz), but
