From 85f2f834e85517307f13e30e630a5fc86f757cb5 Mon Sep 17 00:00:00 2001 From: Hui Wang Date: Wed, 27 Jun 2012 16:19:18 +0800 Subject: [PATCH] can: flexcan: use be32_to_cpup to handle the value of dt entry The freescale arm i.MX series platform can support this driver, and usually the arm cpu works in the little endian mode by default, while device tree entry value is stored in big endian format, we should use be32_to_cpup() to handle them, after modification, it can work well both on the le cpu and be cpu.
