[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. Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
