Subject: [PATCH v3 12/12] ARM: dts: blanche: add Ethernet support
Date: Thu, 09 Jun 2016 00:36:31 +0300 [thread overview]
Message-ID: <1684757.OTRo8llZyo@wasted.cogentembedded.com> (raw)
In-Reply-To: <12536856.AsKMEpuejQ@wasted.cogentembedded.com>
R8A7792 SoC doesn't have the EtherMAC core, so SMSC LAN89218 Ethernet
chip was used instead on the Blanche board; this chip is compatible with
SMSC LAN9115 for which there's a (device tree aware) driver. Describe
the chip in the Blanche device tree; enable DHCP and NFS root in the
kernel command line for the kernel booting.
