[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>

/*
[ARM] 4124/1: Rename mach-at91rm9200 and arch-at91rm9200 directories Now that Linux includes support for the Atmel AT91SAM9260 and AT91SAM9261 processors in addition to the original Atmel AT91RM9200 (with support for more AT91 processors pending), the "mach-at91rm9200" and "arch-at91rm9200" directories should be renamed to indicate their more generic nature. The following git commands should be run BEFORE applying this patch: git-mv arch/arm/mach-at91rm9200 arch/arm/mach-at91 git-mv include/asm-arm/arch-at91rm9200 include/asm-arm/arch-at91 Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

[ARM] 3605/1: AT91RM9200 Power Management Patch from Andrew Victor This patch adds the core Power Management support for the AT91RM9200 processor. It will support suspend-to-RAM and standby modes. The suspend-to-RAM functionality is not 100% complete. The code that needs to be execute from the internal SRAM to restore the system is outstanding. For now we just fall through to Standby mode. The AT91-specific at91_suspend_entering_slow_clock() function will eventually be replaced by clk_must_disable() once that functionality is added to mainline clock API. Patch from David Brownell.
