SAN People 73a59c1c4a [ARM] 3240/2: AT91RM9200 support for 2.6 (Core)
Patch from SAN People

Following changes were made to clock.c:

1) Replaced <asm/hardware/clock.h> with <linux/clk.h>
2) Removed old unused clk_enable & clk_disable.
3) Replaced clk_use/clk_unuse with clk_enable/clk_disable.

Otherwise it's the same as the previous patch.
