[wellsk40 at gmail.com]

This patch set introduces support for the LPC32xx touchscreen
controller driver. The LPC32xx touchscreen controller supports
automated event detection and conversion for resistive touchscreens.

The patch can be pulled from:
	git://git.lpclinux.com/linux-2.6-lpc ts-lpc32xx_v2

v2 includes updates from the initial review of the TSC driver..
	All local TSC_* macros have been prefixed with LCP32XX_
	Added lpc32xx_ prefix to stop_tsc() and start_tsc()
	Moved clk_enable and clk_disable into lpc32xx_start_tsc()
		and lpc32xx_stop_tsc() functions
	Added ->open and ->close methods using the start and
		stop tsc functions
	Removed use of devm_* functions. Modified error unwinding
		and _remove() based on this change.
	Fixed an error return condition from input_register_device()
	Fixed use of input_free_device
	Added a use count check for suspend and resume so device
		state isn't altered if it isn't open
