From 610578a3abec7839a56d9dc058c37f6cd2982e10 Mon Sep 17 00:00:00 2001 From: Marc Kleine-Budde Date: Mon, 2 Jul 2012 11:03:00 +0200 Subject: ARM: imx: enable flexcan on imx25, imx35, imx53, imx6q Aas the flexcan driver has DT binding for some time now. This patch makes the flexcan driver available in the can drivers menu if a SOC with flexcan is enabled.
