Configure the i2c pins as GPIO outputs and use the i2c-gpio driver to control the Semtech SX9512 touch controller. This fixes spurious errors in i2c transactions even at 1kHz with the native i2c driver. leds green:wan: Setting an LED's brightness failed (-6) Signed-off-by: David Bauer <mail@david-bauer.net>
