Patch from David Brownell
ARM genirq cleanups/updates:
- Start switching platforms to newer APIs
* use "irq_chip" name, not "irqchip"
* providing irq_chip.name
- Show irq_chip.name in /proc/interrupts, like on x86.
This update a bit more than half of the ARM code. The irq_chip.name
values were chosen to match docs (if I have them) or be otherwise
obvious ("FPGA", "CPLD", or matching the code).

In all current use cases, "chipdata" is used to store an iomem address.
Mark it with __iomem, and rename it to 'base'. Leave the accessor macros
alone.

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.

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.

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.
