Since 193ab2a6070039e7ee2b9b9bebea754a7c52fd1b, various AT91 boards don't register at91_udc anymore due to depending on a now non-existing symbol. Fix the symbol name.

2011-11-22macb: unify at91 and avr32 platform dataJamie Iles1-3/+3
Both at91 and avr32 defines its own platform data structure for the macb driver and both share common structures though at91 includes a currently unused phy_irq_pin. Create a common macb_platform_data for macb that both at91 and avr32 can use. In future we can use this to support other architectures that use the same IP block with the macb driver. v2: rename eth_platform_data to macb_platform_data and allow at91_ether to share the platform data with macb.

2008-08-01Fix rename of at91_nand -> atmel_nandPieter du Preez1-1/+1
Structs called at91_nand_data where renamed to atmel_nand_data and configs called *MTD_NAND_AT91* where renamed to *MTD_NAND_ATMEL*. This was unfortunately not done consistently, causing NAND chips not being initialised on several ARM boards. I am aware that the author of the original change did not rename MTD_NAND_AT91_BUSWIDTH to MTD_NAND_ATMEL_BUSWIDTH, for example. All *MTD_NAND_AT91* where renamed to *MTD_NAND_ATMEL* in order to keep naming consistency. This patch was only tested on a MACH_SAM9_L9260, as this is the only ARM board I have to my disposal.

2008-04-17[ARM] 4982/1: [AT91] Drop old-style UART initialization (Part 1)Andrew Victor1-3/+4
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 Victor1-0/+85

2008-01-26[ARM] 4760/1: [AT91] SPI CS0 errata on AT91RM9200Andrew Victor1-2/+5
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 Victor1-22/+0

2008-01-26[ARM] 4757/1: [AT91] UART initializationAndrew Victor1-22/+92
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 Victor1-1/+1
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.

2007-11-26[ARM] 4650/1: AT91: New-style init of I2C, support for i2c-gpioAndrew Victor1-3/+38
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().

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.

2007-02-08[ARM] 4143/1: AT91: Prepare for AT91SAM9263 supportAndrew Victor1-2/+2
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 Victor1-0/+875
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>
