Subject: [PATCH] rcar-vin: use monotonic timestamps
Date: Thu, 07 May 2015 08:26:21 +0200	[thread overview]
Message-ID: <554B058D.2040001@xs4all.nl> (raw)

Even though the rcar-vin driver tells userspace that it will give a monotonic
timestamp, it is actually using gettimeofday. Replace this with a proper
monotonic timestamp.
