From 5f83dc93b242e16bf45bbea785ace4268828ce01 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Mon, 12 Jun 2017 12:37:33 -0400 Subject: [PATCH] net: dsa: mv88e6xxx: prefix Port Status macros For implicit namespacing and clarity, prefix the common Port Status Register macros with MV88E6XXX_PORT_STS and the ones which differ between implementations with a chosen reference model (e.g. MV88E6352_PORT_STS_EEE.) Document the register and prefer ordered hex masks values for all Marvell 16-bit registers. Signed-off-by: Vivien Didelot Signed-off-by: David S.
