From 3ad2d861362031dac8b2bba78a8f4c575300948f Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Mon, 7 Feb 2011 10:46:59 +0200 Subject: OMAP: OneNAND: determine frequency in one place OneNAND frequency is determined when calculating GPMC timings. Return that value instead of determining it again in the OMAP OneNAND driver.
