From aff36ea92ec0700cd9241bf01e72956a3ab9600e Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Mon, 12 Nov 2012 14:34:31 +0000 Subject: [PATCH] i2c: mxs: Fix TIMING2 register value According to FSL, the value in the TIMING2 register shall be 0x00300030 instead of what's written in the datasheet. This new value correlates with older STMP36xx datasheet. Issues were detected in Linux when this register was misconfigured, so write this correct value.
