++ bool "Use GPIO for i2c instead of built-in TWI module"
++ help
++ The driver for the built-in TWI module has been plagued by
++ various problems, while the i2c-gpio driver is based on the
++ trusty old i2c-algo-bit bitbanging engine, making it work
++ on pretty much any setup.
++
++ Choose 'Y' here if you're having i2c-related problems and
++ want to rule out the i2c bus driver.

+Subject: [PATCH] NGW100: Wire up the ISI
+
+Since the NGW100 doesn't actually have a camera on board, this patch
+merely serves as an example on how you might wire up the ISI on a
+board that does have a camera.

++ Select this if you want to use the PSIF peripheral to hook up PS/2
++ devices to your STK1000. This will require a hardware modification to
++ work correctly, since PS/2 devices require 5 volt power and signals,
++ while the STK1000 only provides 3.3 volt.
++
++ Say N if you have not modified the hardware to boost the voltage, say
++ Y if you have level convertion hardware or a PS/2 device capable of
++ operating on 3.3 volt.
