Message:

From: Willie <willie_chen@…>

Use GPIOs to control LEDs.

gta02-leds.patch:
drivers/leds/leds-neo1973-gta02.c (gta02led_probe): turn off PWMs and set GPIO

pins controlling LEDs as outputs

fix-gpio-led-patch-still-pwm-t3.patch

Starting up all the PWMs seems to be needed for PWM3 operation
and FIQ / HDQ / VIB operation. But after starting, turn the
LEDs to GPIO-only.

Applies on top of Willie's patch

gta02-leds.patch:
drivers/leds/leds-neo1973-gta02.c (gta02led_probe): revert turning off PWMs
drivers/leds/leds-neo1973-gta02.c (gta02led_probe): unconditionally enable PWM
drivers/leds/leds-neo1973-gta02.c (gta02led_probe): turning off PWMs at the end
