From 50484ff4d11c1eca0059f3b3d407ecec0f1b83b0 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Mon, 9 May 2016 13:22:54 -0400 Subject: [PATCH] net: dsa: mv88e6xxx: factorize GLOBAL_CONTROL_2 setup All switch models setup the GLOBAL_CONTROL_2 register with slightly differences. Since the cascade mode is valid even in a single chip setup, factorize such configuration. Signed-off-by: Vivien Didelot Signed-off-by: David S.
