[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] 3954/1: AT91: Update drivers for new headers This patch updates the drivers (and other files) which include the hardware headers. This fixes the breakage introduced in patches 3950/1 and 3951/1 (those patches were getting big). The AVR32 architecture uses the same serial driver and had its own copy of at91rm9200_pdc.h. Renamed it to at91_pdc.h Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

[ARM] 4143/1: AT91: Prepare for AT91SAM9263 support The Atmel AT91SAM9263 processor includes many more integrated peripherals than Atmel's previous ARM9-based AT91 processors, so this has necessitated a few changes to the core AT91 support. These changes are: * The system peripheral I/O region we remap has increased from 0xFFFA0000..0xFFFFFFFF to 0xFFF78000..0xFFFFFFFF. * The increased I/O region forces changes to entry-macro.S and debug-macro.S due to ARM's limited immediate offset addressing modes. * Maximum number of GPIO banks increases to 5. * 2 MMC controllers so the board-setup code needs to specify which controller it wishes to use when calling at91_add_device_mmc().
