From 2cd451792db174382aaca96c75bc3bf47a6065fe Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Wed, 14 Nov 2012 11:14:26 +0800 Subject: spi/omap: fix D0/D1 direction confusion 0384e90b8 ("spi/mcspi: allow configuration of pin directions") did what it claimed to do the wrong way around. D0/D1 is configured as output by *clearing* the bits in the conf registers, hence also breaking the former default behaviour. Fix this before that change is merged to mainline.
