From 33e739973defbe6b88a2375f174571bf7e72d8fd Mon Sep 17 00:00:00 2001 From: Philip Rakity Date: Fri, 7 Jan 2011 11:27:46 -0800 Subject: ARM: mmp: PXA910 drive strength FAST using wrong value Drive strength for PXA910 is a 2 bit value but because of the mapping in plat-pxa/mfp.h needs to be shifted up one bit to handle real location in mfp registers. (MMP2 and PXA910 drive strength start at bit 11 while PXA168 starts at bit 10). Values 0, 1, 2, and 3 effectively need to be 0, 2, 4, and 6 to fit into register. 8 does not work.
