* [ARM] 4289/1: AT91: SAM9260 NAND flash timingAndrew Victor2007-03-29
| | | | | | | | | | | | Fix the NAND flash timings on the AT91SAM9260. The current timings lead to the detection of a number of bad blocks. These timings are now set the same as on the AT91SAM9263.

* [PATCH] gpio_direction_output() needs an initial valueDavid Brownell2007-03-16
| | | | | | | | | | | | | | | | | | | | | | | | | | It's been pointed out that output GPIOs should have an initial value, to avoid signal glitching ... among other things, it can be some time before a driver is ready. This patch corrects that oversight, fixing - documentation - platforms supporting the GPIO interface - users of that call (just one for now, others are pending) There's only one user of this call for now since most platforms are still using non-generic GPIO setup code, which in most cases already couples the initial value with its "set output mode" request. Note that most platforms are clear about the hardware letting the output value be set before the pin direction is changed, but the s3c241x docs are vague on that topic ... so those chips might not avoid the glitches.

* [ARM] 4232/1: AT91: Generic GPIO bugAndrew Victor2007-02-22
| | | | | | | | | The new gpio_direction_input() and gpio_direction_output() functions were both enabling output mode. When configuring a GPIO for input mode, you need to program the ODR (Output Disable Register).

* [ARM] 4231/1: AT91: Merge and typo fixes.Andrew Victor2007-02-22
| | | | | | | | | | | The duplicate file "include/asm-arm/arch-at91rm9200/entry-macro.S" can be removed - it was already moved to include/asm-arm/arch-at91/. Fix 3 small typo's - two in comments, and the incorrect clock was specified for the LCD device.

* [ARM] 4192/1: AT91: Support for AT91SAM9XE processors.Andrew Victor2007-02-15
| | | | | | | | | | | | | | Add support for the Atmel AT91SAM9XE range of processors. These are basically AT91SAM9260's with different amounts of internal SRAM and Flash. We make use of the existing AT91SAM9260 support, but just perform run-time detection of the size of the internal SRAM. Original patch from Nicolas Ferre.

* [ARM] 4154/1: AT91: Clock updateAndrew Victor2007-02-08
| | | | | | | | | | | | | | | | | | | | Unconditionally disabling the PCKs (Programmable Clocks) is not a good idea as it breaks boards that depend on those clocks being enabled by bootloaders. Therefore only disable unused clocks late in the init process, giving the board init code the chance to claim the clock. Patch from Steven Scholz. Since the HCK clocks on SAM9261 are already being registered as a independent clocks, we don't need the special case for HCK0 on the SAM9261. Platform-init code and drivers should use the clock API to enable/disable the clock. Patch from Nicolas Ferre.

* [ARM] 4143/1: AT91: Prepare for AT91SAM9263 supportAndrew Victor2007-02-08
| | | | | | | | | | | | | | | | | | | | | 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().

* [ARM] 4124/1: Rename mach-at91rm9200 and arch-at91rm9200 directoriesAndrew Victor2007-02-08
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>
