Subject: [PATCH v5 net-next 04/10] ARM: dts: armada-xp: add buffer manager nodes
Date: Thu, 10 Mar 2016 11:09:12 +0100 [thread overview]
Message-ID: <1457604558-1121-5-git-send-email-gregory.clement@free-electrons.com> (raw)
In-Reply-To: <1457604558-1121-1-git-send-email-gregory.clement@free-electrons.com>
From: Marcin Wojtas <mw@semihalf.com>
Armada XP network controller supports hardware buffer management (BM).
Since it is now enabled in mvneta driver, appropriate nodes can be added
to armada-xp.dtsi - for the actual common BM unit (bm@c0000) and its
internal SRAM (bm-bppi), which is used for indirect access to buffer
pointer ring residing in DRAM.
Pools - ports mapping, bm-bppi entry in 'soc' node's ranges and optional
parameters are supposed to be set in board files.
