From 94ceaa26320fc48c16ea299ee7b546a0203d95b5 Mon Sep 17 00:00:00 2001 From: Vince Bridgers Date: Thu, 31 Jul 2014 15:49:15 -0500 Subject: dts: Add bindings for multicast hash bins and perfect filter entries This change adds bindings for the number of multicast hash bins and perfect filter entries supported by the Synopsys EMAC. The Synopsys EMAC core is configurable at device creation time, and can be configured for a different number of multicast hash bins and a different number of perfect filter entries. The device does not provide a way to query these parameters, therefore parameters are required. The Altera Cyclone V SOC has support for 256 multicast hash bins and 128 perfect filter entries, and is different than what's currently provided in the stmmac driver.
