This patch set aims at bringing a basic device tree support for the sam9261. It's mostly based on the sam9263 stuff. It introduces a new driver for the smc/ebi bus. It's used to configure the EBI from the DT. I haven't documented its DT bindings yet. Timings can be provided as raw values or nanoseconds.
Change since V1: * changed the DT representation to use address translation and separate the timings' configuration from the device properties by adding a "simple-bus" inetrmediate node. * moved the smc driver from drivers/bus to drivers/memmory * smc driver now accepts timings in nanoseconds as well as raw register values * smc driver can clip the timings if they're out of bound and dump them to the console * DM9000 timings are now described in nanosecs (for the virtue of example)
supported features: * dbgu * nand * lcd * ethernet * leds
