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.

2008-04-29i2c: Convert most new-style drivers to use module aliasingJean Delvare
Based on earlier work by Jon Smirl and Jochen Friedrich. Update most new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. I've left the video drivers apart (except for SoC camera drivers) as they're a bit more diffcult to deal with, they'll have their own patch later.

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] 4989/1: [AT91] SAM9 ClockSource / ClockEventsAndrew Victor
Update AT91SAM9/CAP9 PIT driver to use generic time and clockevent infrastructure: - Clocksource gives sub-microsecond timestamp precision, assuming memory is clocked at over 16 MHz. It's less than a 32 bit counter, unless it's is also generating IRQs. - Clockevent device supports periodic mode only; no oneshot support from this hardware. No IRQs generated unless it's the active clocksource. Later, another timer (probably from a TC module) can provide a oneshot clockevent device to get NO_HZ and High-Res-Timer behavior. This also updates the timekeeping to use the actual master clock rate on the system, instead of compile-time <asm/arch/timex.h> constants matching what Atmel's EK boards use. (Product boards may well differ!) Plus cleanup: rename "*_timer*" symbols to "*_pit*" (there are other timers, but only one PIT); shorter lines; remove needless CPP stuff; make several symbols static; etc. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-02-06atmel_lcdfb: backlight controlDavid Brownell
On the sam9 EK boards, the LCD backlight is hooked up to a PWM output from the LCD controller. It's controlled by "contrast" registers though. This patch lets boards declare that they have that kind of backlight control. The driver can then export this control, letting screenblank and other operations actually take effect ... reducing the typically substantial power drain from the backlight. Note that it's not fully cooked - doesn't force backlight off during system suspend - the "power" and "blank" events may not be done right This should be easily added in the future.

2008-02-04[ARM] 4660/3: at91: allow selecting UART for early kernel messagesGuennadi Liakhovetski
Currently early kernel messages, i.e., those from uncompression, go to the debugging UART. And if it is enabled in the platform configuration, but not initialized by the bootloader, the machine hangs, waiting for UART status change. Besides, having those messages on another UART - typically the console UART - may be preferrable. This patch allows selecting the UART in kernel configuration.

2008-02-04[ARM] 4739/1: at91sam9263: make gpio bank C and D irqs workDavid Brownell
On the at91sam9263, IRQs for GPIO banks C and D don't currently work. This is because banks C, D, and E share one clock and toplevel IRQ, but the AT91 code setting up and handling GPIO IRQs expects no sharing. This patch: - Fixes GPIO IRQ setup and handling to cope with GPIO banks that are shared like on sam9263 chips, by setting up a list of those banks and making the IRQ dispatching logic scan that list. - Precomputes the address of each bank's registers, saving it with other per-bank data so that it no longer needs to be constantly recomputed during IRQs and other GPIO operations. That shrinks hot-path code, while helping the GPIO bank irq updates. - Fixes a minor bug where IRQ_TYPE_NONE was wrongly rejected (it just means "use the default", which is "both edges" here).

2008-02-01Suspend: Introduce begin() and end() callbacksRafael J. Wysocki
On ACPI systems the target state set by acpi_pm_set_target() is reset by acpi_pm_finish(), but that need not be called if the suspend fails.  All platforms that use the .set_target() global suspend callback are affected by analogous issues. For this reason, we need an additional global suspend callback that will reset the target state regardless of whether or not the suspend is successful.  Also, it is reasonable to rename the .set_target() callback, since it will be used for a different purpose on ACPI systems (due to ACPI 1.0x code ordering requirements). Introduce the global suspend callback .end() to be executed at the end of the suspend sequence and rename the .set_target() global suspend callback to .begin(). Signed-off-by: Rafael J.

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] 4759/1: [AT91] Buttons on CSB300Andrew Victor
Support for the 3 GPIO-connected buttons on the CSB300 board. Based on wakeup testing code 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] 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] 4756/1: [AT91] Makefile cleanupAndrew Victor
Cleanup the main AT91 makefile. 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>
2008-01-26[ARM] 4752/1: [AT91] RTT, RTC and WDT peripherals on SAM9Andrew Victor
Add platform_device and initialization for the RTT (Real Time Timer) and WDT (Watchdog) integrated in the Atmel AT91SAM9 processors. For SAM9263, register both RTT peripherals. [From: David Brownell <dbrownell@users.sourceforge.net>] Provide platform_resources for RTT peripherals [From: David Brownell <dbrownell@users.sourceforge.net>] Add support for RTC peripheral on AT91SAM9RL (same RTC peripherals as AT91RM9200) [From: David Brownell <dbrownell@users.sourceforge.net>] Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
