Subject: [PATCH 2/2] ravb: skip gPTP start/stop on R-Car gen3
Date: Sat, 06 Feb 2016 17:47:22 +0300 [thread overview]
Message-ID: <1661604.7YJiO2yUKB@wasted.cogentembedded.com> (raw)
In-Reply-To: <15000430.RmSAhz5Ejy@wasted.cogentembedded.com>
When adding support for the R-Car gen3 gPTP active in configuration mode,
some call sites of ravb_ptp_{init|stop}() were missed due to an oversight.
Add checks for the R-Car gen2 SoCs around these...
Fixes: f5d7837f96e5 ("ravb: ptp: Add CONFIG mode support")
