From 4aaf06415f795098b398f728ddb1324020ebe544 Mon Sep 17 00:00:00 2001 From: "Arnout Vandecappelle (Essensium/Mind)" Date: Mon, 27 Aug 2012 01:37:11 +0000 Subject: [PATCH] OMAP3: add definition of CTRL_WKUP_CTRL register AM/DM37x SoCs add the CTRL_WKUP_CTRL register. It contains the GPIO_IO_PWRDNZ bit, which is required to be set to enable the I/O pads of gpio_126, gpio_127 and gpio_129.
