[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: generic.h: Add include safe guards The generic.h header file doesn't have any safe guards against multiple inclusion. It only worked so far because all the symbols defined in it were extern, but this is a rather fragile assumption.

ARM: at91: pm: prepare for multiplatform Split at91_pm_init() in three variants that are called by the respective SoCs .init_machine. This allows to remove the of_machine_is_compatible() calls and move at91_pm_init() out of arch_initcall() which is required for multiplatform.

#ifdef CONFIG_PM
ARM: at91/trivial: unify functions and machine names Remove the string "(Device Tree)" after the machine name because all AT91 machines use the DT nowadays. Also change some function names to unify following the convention: - at91sam9xxx aren't named sam9, 9xxx but with the full name - sama5 are the ones that don't have the at91 prefix anymore.

ARM: at91: fix pm declarations In a recent rearrangement of the at91 pm initialization code, a broken set of declarations was added for the !CONFIG_PM-case, leading to this link error: arch/arm/mach-at91/board-dt-sama5.o: In function `at91_rm9200_pm_init': arch/arm/mach-at91/generic.h:40: multiple definition of `at91_rm9200_pm_init' arch/arm/mach-at91/setup.o:arch/arm/mach-at91/generic.h:40: first defined here arch/arm/mach-at91/board-dt-sama5.o: In function `at91_sam9260_pm_init': arch/arm/mach-at91/generic.h:41: multiple definition of `at91_sam9260_pm_init' arch/arm/mach-at91/setup.o:arch/arm/mach-at91/generic.h:41: first defined here arch/arm/mach-at91/board-dt-sama5.o: In function `at91_sam9g45_pm_init': arch/arm/mach-at91/generic.h:42: multiple definition of `at91_sam9g45_pm_init' arch/arm/mach-at91/setup.o:arch/arm/mach-at91/generic.h:42: first defined here This adds the missing 'static inline' to the declarations to avoid creating a copy of the functions in each file that includes the header.
