Subject: [PATCH 5/6] ppc: mpc85xx:gianfar: add stashing support
Date: Thu, 13 Mar 2014 18:10:03 +0000 [thread overview]
Message-ID: <1394734204-8181-7-git-send-email-renaud.barbier@ge.com> (raw)
In-Reply-To: <1394734204-8181-1-git-send-email-renaud.barbier@ge.com>
The eTSEC 2.0 devices found on the 85xx family of SoCs support stashing
buffer descriptors in the L2 cache. This updates the device tree fixup
for these devices to ensure that the stashing related properties used
by Linux are initialised correctly.
