TODO:
	- see if vx855 gpio API can be made similar enough to cs5535 so we can
	  share more code
	- convert all uses of the old GPIO API from <linux/gpio.h> to the
	  GPIO descriptor API in <linux/gpio/consumer.h> and look up GPIO
	  lines from device tree, ACPI or board files, board files should
	  use <linux/gpio/machine.h>
	- allow simultaneous XO-1 and XO-1.5 support

Please send patches to Greg Kroah-Hartman <greg@kroah.com> and
