* ARM: at91: rename board-dt to more specific name board-dt-sam9Jean-Christophe PLAGNIOL-VILLARD2013-03-131-59/+0
| | | | | | | | | | | We will produce a board-dt file per SoC core type. That will ease code readability and will prevent from including superfluous code for supporting machines that will never be compiled together (particularly the ARM9 and C-A5 upcoming SoCs).

* ARM: delete struct sys_timerStephen Warren2012-12-241-1/+1
| | | | | | | | | | | | | | | | | | Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

* ARM: at91/pio: add new PIO3 featuresNicolas Ferre2012-03-011-0/+1
| | | | | | | | | | | | | | | This patch adds the support for new PIO controller found on some at91sam SOCs. - more peripheral multiplexing - more features to configure on a PIO (pull-down, Schmitt trigger, debouncer) - support for several IRQ triggering features (type and polarity) Support for those new features are retrieved from the device tree compatibility string. Debugfs at91_gpio file is updated to monitor configuration. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
* ARM: at91: AIC and GPIO IRQ device tree initializationNicolas Ferre2012-03-011-1/+10
| | | | | | | | | | | | | | | | Both AIC and GPIO controllers are now using the standard of_irq_init() function to initialize IRQs in case of DT use. The DT specific initialization functions are now separated from the non-DT case and are now using "linear" irq domains. The .map() irqdomain operation is responsible for positioning the IRQ handlers. In AIC case, the Linux IRQ number is directly programmed in the hardware to avoid an additional reverse mapping operation. The AIC position its irq domain as the "default" irq domain. For DT case, the priority is not yet filled in the SMR. It will be the subject of another patch. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>

* ARM: at91: dt: at91sam9g45 family and board device tree filesNicolas Ferre2011-10-251-0/+122
Create a new device tree source file for Atmel at91sam9g45 SoC family. The Evaluation Kit at91sam9m10g45ek includes it. This first basic support will be populated as drivers and boards will be converted to device tree. Contains serial, dma and interrupt controllers. The generic board file still takes advantage of platform data for early serial init. As we need a storage media and the NAND flash driver is not converted to DT yet, we keep old initialization for it.
