Thom Johansen 3c7278f405 Reworked backlight fading by GPIO based PWM to work for other targets
than H1x0. iPod Nano and 5G backlight fading is enabled. To try for your
device, just define HAVE_BACKLIGHT_PWM_FADING in the relevant
config-xxxx.h file. NOTE: Will break your settings, so save a config
file first.
