* arm: at91: clock: Add the generated clock supportWenyou Yang2015-11-032-0/+23
| | | | | | | | | | | Some peripherals may need a second clock source that may be different from the system clock. This second clock is the generated clock (GCK) and is managed by the PMC via PMC_PCR. For simplicity, the clock source of the GCK is fixed to PLLA_CLK.
