From 8808ccefd0573ddfdf612898dbe959f4f2feff15 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Thu, 13 Sep 2012 11:01:03 +1000 Subject: [PATCH] drivers/misc/lis3lv02d/lis3lv02d_spi.c: add DT matching table passthru code MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit If probed from a device tree, this driver now passes the node information to the generic part, so the runtime information can be derived. Successfully tested on a PXA3xx board.
