From a4ff93c185787412936bc8414f14f50bdd56e546 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 18 Sep 2014 09:03:36 -0700 Subject: ARM: dts: Do not set pulls for I2C lines There are external pulls on these lines and enabling the internal pulls can cause issue. This is because the internal pulls are parallel with the external pulls. So let's clear the internal I2C pulls.

Note that the reset GPIO will eventually go to the driver. For now let's just pull it down and skip any further reset in case the bootloader has configured the MAC address so NFSroot works. Also note that after 3430-sdp are using proper GPMC timings we can remove the tests for smsc,lan91c94 in gpmc.c.
