From 4e9642528cf5d8b5dee5818d796a4535b1748554 Mon Sep 17 00:00:00 2001 From: Charulatha V Date: Mon, 4 Jul 2011 04:08:46 -0700 Subject: omap: ZOOM: QUART: Request reset GPIO Reset GPIO (OMAP_GPIO_152) for QUART in zoom2/zoom3 debug-board is not requested at all. This would lead to problems if this GPIO is wrongly requested. Hence request OMAP GPIO 152 for QUART RESET but do not apply a reset pulse as it would reset QUART and disturb the QUART settings.
