Subject: [PATCH v10 6/6] MIPS: SGI-IP27: Enable ethernet phy on second Origin 200 module
Date: Tue, 15 Oct 2019 14:09:51 +0200 [thread overview]
Message-ID: <20191015120953.2597-7-tbogendoerfer@suse.de> (raw)
In-Reply-To: <20191015120953.2597-1-tbogendoerfer@suse.de>
PROM only enables ethernet PHY on first Origin 200 module, so we must
do it ourselves for the second module.
