Andrew Victor abbea71872 [ARM] 3348/1: Disable GPIO interrupts
Patch from Andrew Victor

disable_irq() lazily disables the interrupt, so the IRQ is only disabled
once the interrupt occurs again.  The GPIO interrupt handler therefore
must first check disable_depth to see if the IRQ needs to be disabled.

Orignal patch by Bill Gatliff.

Andrew Victor df666b9c51 [ARM] 3325/2: GPIO function to control multi-drive (open collector) capability
Patch from Andrew Victor

This patch adds the at91_set_multi_drive() function to enable/disable
the multi-drive (open collector) pin capability on the AT91RM9200
processor.

This is necessary to fix the UDC (USB Gadget) driver for the AT91RM9200
board as it will not allow the board reset line to be pulled low if the
pullup is not driven as an open collector output as the boards are wired
to the USB connector on both the DK/EK.

This version of the patch updates it to 2.6.16-rc4.

Nicolas Pitre 946d4935fc [ARM] 3260/1: remove phys_ram from struct machine_desc (part 2)
Patch from Nicolas Pitre

This field is redundent since it must be equal to PHYS_OFFSET anyway.

Now that no code uses it anymore, mark it deprecated and remove all
initializations from the tree.

SAN People 73a59c1c4a [ARM] 3240/2: AT91RM9200 support for 2.6 (Core)
Patch from SAN People

Following changes were made to clock.c:

1) Replaced <asm/hardware/clock.h> with <linux/clk.h>
2) Removed old unused clk_enable & clk_disable.
3) Replaced clk_use/clk_unuse with clk_enable/clk_disable.

Otherwise it's the same as the previous patch.
