2009-02-14[ARM] 5390/1: AT91: Watchdog fixesAndrew Victor
The recently merged AT91SAM9 watchdog driver uses the AT91SAM9X_WATCHDOG config variable, whereas the original version of the driver (and the platform support code) used AT91SAM9_WATCHDOG. This causes the watchdog platform_device to never be registered, and therefore the driver not to be initialized. This patch: - updates the platform support code to use AT91SAM9X_WATCHDOG. - includes <linux/io.h> to fix compile error (same fix as was applied to at91rm9200_wdt.c) - fixes comment regarding watchdog clock-rates in at91rm9200.

2008-12-01[ARM] 5288/1: [AT91] Remove SMC configuration from devices.c filesAndrew Victor
In at91_add_device_nand(), do not configure the Static Memory controller with specific timing values. The *_devices.c files are board independent, and the SMC timing values are specific to the NAND devices that are installed on the board. The board-specific files are now responsible for configuring the Static Memory controller (if the don't want to leave it up to a bootloader).

2008-08-01Fix rename of at91_nand -> atmel_nandPieter du Preez
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.

2008-05-14atmel_lcdfb: fix initialization of a pre-allocated framebufferNicolas Ferre
Fix initialization of framebuffer not calling ioremap_writecombine() function and not using internal SRAM for at91sam9rl. This is a little rework of the "Don't initialize a pre-allocated framebuffer" patch that corrects the call to ioremap_writecombine() function. It also cuts the use of internal SRAM for at91sam9rl : it is a bit small for a framebuffer.

2008-04-28atmel_lcdfb: don't initialize a pre-allocated framebufferHaavard Skinnemoen
If the user specified a fixed framebuffer address on the command line, it may have been initialized already with a splash image or something, so we shouldn't clear it. Therefore, we should only initialize the framebuffer if we allocated it ourselves. This patch also updates the AVR32 setup code to clear the framebuffer if it allocated it itself, i.e. the user didn't provide a fixed address or the reservation failed. I've updated the at91 platform code as well so that it initializes the framebuffer if it is located in SRAM, but I haven't tested that it actually works.

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

2008-04-04[ARM] 4908/1: [AT91] RTT platform_device fixAndrew Victor
The RTT-as-RTC driver will search for the user-specified RTT peripheral via ID number (0 .. 1). Therefore if the processor only contains a single RTT peripheral, we need to set its platform_device.id to "0" instead of "-1". Also add the missing platform_device resource for the CAP9 processor.

2008-04-04[ARM] 4902/1: [AT91] SAM9/CAP9 memory controller headerAndrew Victor
The AT91CAP9 processor includes the same Static Memory Controller (SMC) peripheral as the SAM9 processors, but replaces the SDRAM Controller with a DDR/SDR Controller (DDRSDRC). This patch splits the existing include/asm-arm/arch-at91/at91sam926x_mc.h into at91sam9_sdramc.h and at91sam9_smc.h. It also adds an at91cap9_ddrsdr.h for the DDRSDRC controller.

2008-01-26[ARM] 4758/1: [AT91] LEDsAndrew Victor

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] 4754/1: [AT91] SSC library supportAndrew Victor

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().
