This driver adds support for the Synaptics NavPoint touchpad connected
to a PXA27x SSP port in SPI slave mode. The driver implements a simple
navigation pad. The four raised dots are mapped to UP/DOWN/LEFT/RIGHT
buttons and the centre of the touchpad is mapped to the ENTER button.

V7:
Separated arch/arm/mach-pxa/include/mach/mfp-pxa27x.h changes into a
separate patch, to avoid crossing maintainer boundaries.
This patch now submitted to linux-input instead of linux-arm-kernel.
Improved dev_warn() messages.
navpoint_hardint() now correctly returns IRQ_HANDLED in cases where
reading SSDR does not return IRQ_WAKE_THREAD.
Folded in "Input: navpoint: add clk_prepare/clk_unprepare calls" patch.
Added calls to gpio_is_valid(), gpio_request(), gpio_direction_output().
Rebased from linux-3.2 to linux-3.4-rc2.
