From ba43861277f1858472de4adfc0b28a047484da83 Mon Sep 17 00:00:00 2001 From: Peter Tyser Date: Thu, 24 Mar 2011 18:17:14 -0500 Subject: gpio/ml_ioh_gpio: Fix output value of ioh_gpio_direction_output() The ioh_gpio_direction_output() function was missing a write to set the desired output value. The function would properly set the GPIO direction, but not the output value. The value would have to manually be set with a follow up call to ioh_gpio_set(). Add the missing write so that ioh_gpio_direction_output() sets both the GPIO direction and value.
