Subject: [PATCH v2 05/19] MIPS: SEAD3: Probe ethernet controller using DT
Date: Fri, 26 Aug 2016 15:17:37 +0100 [thread overview]
Message-ID: <20160826141751.13121-6-paul.burton@imgtec.com> (raw)
In-Reply-To: <20160826141751.13121-1-paul.burton@imgtec.com>
Probe the smsc911x ethernet controller using device tree rather than
platform code, reducing the amount of the latter.
Signed-off-by: Paul Burton <paul.burton@imgtec.com>
