2008-04-17[ARM] 4982/1: [AT91] Drop old-style UART initialization (Part 1)Andrew Victor
All the SAM9 boards supported by mainline and the AT91 patches have been converted to the new-style UART initialization. Therefore drop support for the old at91_init_serial() interface for SAM9. at91_uarts[] array can also be marked as __initdata. The warning that no serial-console is defined moved from at91_set_serial_console() to at91_add_device_serial() since the whole point is the board-specific file is not calling at91_set_serial_console().

2008-04-04[ARM] 4909/1: [AT91] Timer/Counter Block platform_devicesAndrew Victor
Register platform_devices for the Timer/Counter Block peripherals found on the AT91RM9200, SAM9 & CAP9 processors. Original patch from David Brownell. Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-01-26[ARM] 4760/1: [AT91] SPI CS0 errata on AT91RM9200Andrew Victor
Due to errata regarding the handling of SPI CS0 on the AT91RM9200, the atmel_spi driver drives CS0 from the SPI controller and not as a GPIO pin. We therefore need to configure CS0 for use by the controller Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-01-26[ARM] 4758/1: [AT91] LEDsAndrew Victor
Move the LED initialization code out of the various *_devices.c files, and into leds.c. Also add support for NEW_LEDs. Patch from David Brownell. Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-01-26[ARM] 4757/1: [AT91] UART initializationAndrew Victor
Modify the UART initialization to allow the board-initialization code to specify which pins are connected, and which pins should therefore be initialized. The current at91_init_serial() will continue to work as-is, but is marked as "deprecated" and will be removed once the board-specific files has been updated to use the new interface. As in the AVR32 code, we assume that the TX and RX pins will always be initialized. Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-01-26[ARM] 4755/1: [AT91] NAND updateAndrew Victor
Map the complete memory region (SZ_256M) as is done on the other AT91 processors. The SMC_SMARTMEDIA bit should be set in the EBI controller to enable the hardware NAND logic.

2008-01-26[ARM] 4754/1: [AT91] SSC library supportAndrew Victor
Core support of the Atmel SSC library for all Atmel AT91 processors. Based on David Brownell's initial patch for the AT91RM9200. Signed-off-by: Andrew Victor <linux@maxim.org.za> Acked-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-01-26[ARM] 4753/1: [AT91] Use DMA_BIT_MASKAndrew Victor
Replace hard-coded DMA mask (0xffffffff) with DMA_BIT_MASK(32) as defined in dma-mapping.h. Set "dma_mask" field for the UART platform_devices. Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-11-26[ARM] 4650/1: AT91: New-style init of I2C, support for i2c-gpioAndrew Victor
The AT91 I2C driver is currently marked as "broken" due to hardware issues. This patch enables AT91-based platforms to also use the bitbanged GPIO for I2C. This updates platform setup logic (setting up an i2c-gpio device using the same pins as the i2c-at91 device, unless only the BROKEN driver is enabled). Also make use of the new-style initialization of I2C devices using i2c_register_board_info().

2007-07-20[ARM] 4478/1: AT91: Convert AT91RM9200 to use atmel_spi driverAndrew Victor
Convert the AT91RM9200 platform-setup code to use the new atmel_spi driver (and manually-driven chip-selects), instead of the legacy AT91-only SPI stack. The AT91SAM9 processors are already using the atmel_spi driver. Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-05-11[ARM] 4372/1: Define byte sizes in asm-arm/sizes.hAndrew Victor
Define SZ_512, SZ_256 and SZ_16 in asm-arm/sizes.h. Remove the definitions from the at91*_devices.c files. (Dependent on ARM patch #4370/2) Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-02-08[ARM] 4150/1: AT91: LED updateAndrew Victor
The GPIO pin setup should be handed by the platform-setup code, and not directly by the driver. Original patch from David Brownell. Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-02-08[ARM] 4143/1: AT91: Prepare for AT91SAM9263 supportAndrew Victor
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().

2007-02-08[ARM] 4124/1: Rename mach-at91rm9200 and arch-at91rm9200 directoriesAndrew Victor
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>
