From cd5847ac3a2d561e9d02926c768fd547f418c24d Mon Sep 17 00:00:00 2001 From: Aneesh V Date: Mon, 21 Nov 2011 23:39:00 +0000 Subject: omap4460: fix TPS initialization TPS power IC is controlled using a GPIO (gpio_wk7). This GPIO should be maintained at logic 1 always. As such an internal pull-up on this pin will do the job, driving the GPIO outuput is not needed. This will avoid the need of using GPIO library in SPL and also may save some power.
