Subject: Add kernel support for oprofile callgraphs on AVR32

This patch adds backtracing capability to oprofile profiling in kernel
and user mode on AVR32. This is done by going through the frames on the
stack and adding oprofile traces for all return addresses. The code
being profiled has to be compiled with frame pointers to make this work.

Subject: avr32: Allow fine-grained control over LCDC pins

This replaces the pin_config param with an u64 pin_mask in
at32_add_device_lcdc, allowing a board-maintainer to indivually select
specific lcdc pins.

Subject: ngw100: export J15 through sysfs

The NGW100 board has jumper J15 (near the reset button) which
is unused.  This patch exports it through the GPIO sysfs support
(as /sys/class/gpio/gpio62/value) so that it's easily queried
by boot scripts or whatever might want to know if the jumper
has been installed (value = 0) or not (value = 1, "default").

Subject: avr32: Provide a way to deselect pins in the portmux

Currently, setting up the portmux is completely one-shot: Once a pin is
muxed, the portmux driver will complain loudly and refuse to do anything
if you try to set up the same pin again.

Sometimes, it may be necessary to change the configuration of a pin
after it has been set up initially. This patch adds a way to undo the
previous configuration, allowing the pin to be reconfigured.

MIME-Version: 1.0

The probe function of the pio platform driver lives in the init section
and so a pio device that is created after the init section is discarded
probably results in an oops.  Even if this cannot happen, using
platform_driver_probe is cleaner.  (If this can happen and should be
supported the probe function must live in the devinit section instead.)

Subject: avr32: Allow selecting multiple pins at once

at32_select_periph() now takes an u32 bitmask rather than a single pin.
This allows to set multiple pins at once.
