From 97a8d010e029111e5711a45264a726bedbeb24c4 Mon Sep 17 00:00:00 2001 From: Igal Liberman Date: Tue, 18 Aug 2015 14:47:05 +0300 Subject: net/fman: Support both new and legacy FMan Compatibles Recently the FMan Port and MAC compatibles were changed. This patch aligns the FMan Port and MAC compatibles to the new FMan device tree binding document. The FMan device tree binding document can be found in the Linux kernel: ./Documentation/devicetree/bindings/powerpc/fsl/fman.txt This patch doesn't affect legacy compatibles support.
