+Subject: [PATCH 43/46] can: flexcan: use be32_to_cpup to handle the value of
+ dt entry
+
+commit 85f2f834e85517307f13e30e630a5fc86f757cb5 upstream.
+
+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.
