From 23ec98b680ec53b03de8e7dfac5eb90671344ae4 Mon Sep 17 00:00:00 2001 From: Jagadeesh Bhaskar Pakaravoor Date: Tue, 30 Sep 2008 21:42:46 +0300 Subject: [PATCH] twl4030-gpio: Remove default pullup enable/disable of GPIO One twl4030_request_gpio() should not tamper with the pullup enabling/disabling of the rest of the GPIOs. So removing the default pullup values written to REG_GPIOPUPDCTR1.
