[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: at91: move at91_pmc.h to include/linux/clk/at91_pmc.h This patch moves at91_pmc.h header from machine specific directory (arch/arm/mach-at91/include/mach/at91_pmc.h) to clk include directory (include/linux/clk/at91_pmc.h). We need this to avoid reference to machine specific headers in clk drivers.

[ARM] 3946/1: AT91: at91_arch_reset and at91_extern_irq The external interrupt sources are different on the various AT91 processors. This patch introduces the global 'at91_extern_irq' variable that contains a bitset of the available external interrupt sources. The processor reset mechanism also differs on the various AT91 processors.
