From d36ef6a51df0d9bb840f091adee8b7bf3424b331 Mon Sep 17 00:00:00 2001 From: Vadim Bendebury Date: Fri, 25 Jul 2014 17:34:42 -0700 Subject: ipq806x: implement GPIO API Add implementation of the GPIO API defined in src/include/gpiolib.h. Also, clean up the GPIO driver, make it use pointers instead of integers for register address. This requires a touch in the SPI driver, where the CS GPIO is toggled and in the board function where it enables USB interface. BUG=chrome-os-partner:30489 TEST=tested with the following patches, observed proto0 properly read the board ID.
