* ARM: at91/dma: DMA controller registering with DT supportNicolas Ferre2012-02-291-1/+9
| | | | | | | | | Device tree support on at91sam9g45 family SoC. Only call platform_device_register() if no dma-controller node is found in device tree. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Acked-by: Grant Likely <grant.likely@secretlab.ca>

| | | | | | | | | Driver at91_ide is broken and should not be fixed: remove it. Modification of device files that where making use of it. The PATA driver (pata_at91) is able to replace at91_ide.

* ARM: at91: Fix at91sam9g45 and at91cap9 resetJean-Christophe PLAGNIOL-VILLARD2012-01-206-13/+48
| | | | | | | | | | As on the other sam9 we need to cleanly shutdown the DDRAM before rebooting. On those SoC the SDRAM/DDRAM controller is different. So, the assembly code ends up being not cleanly combined with previous at91sam9_alt_restart function.

* ARM: at91: fix at91rm9200 soc subtype handlingNicolas Ferre2012-01-201-2/+5
| | | | | | | | | | | | | | | | Currently setting it to PQFP changes subtype to BGA as subtypes are swapped in at91rm9200_set_type(). Wrong subtype causes GPIO bank D not to work at all. After this fix, subtype is still set as unknown. But board code should fill it in with proper value. Another information is thus printed. Bug discovery and first implementation made by Veli-Pekka Peltola.

| * ARM: restart: remove the now empty arch_reset()Russell King2012-01-051-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the now empty arch_reset() from all the mach/system.h includes, and remove its callsite. Remove arm_machine_restart() as this function no longer does anything useful. For samsung platforms, remove the include of mach/system-reset.h and plat/system-reset.h from their respective mach/system.h headers as these just define their arch_reset functions. As a result, the s3c2410 and plat-samsung system-reset.h files are no longer referenced, so remove these files entirely.

| * ARM: restart: at91: use new restart hookRussell King2012-01-0510-24/+13
| | | | | | | | | | | | | | | | | | | | | | | | Rather than using a private function pointer, use the existing arm_pm_restart function pointer instead. We no longer need to enable the I-cache in at91sam9_alt_reset() as the caches will now be on when this function is called. Update the function names to use the 'restart' terminology rather than the 'reboot' terminology. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

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.
