Subject: [PATCH 0/2] clocksource: Add renesas-ostm timer driver
Date: Thu, 12 Jan 2017 13:59:50 -0500	[thread overview]
Message-ID: <20170112185952.2780-1-chris.brandt@renesas.com> (raw)

This patch set adds a new clocksource driver that uses the OS Timer
(OSTM) that exists in the R7S72100 (RZ/A1) SoC.

The operation of the driver was tested with a simple user application
that does multiple calls to nanosleep() and gettimeofday().

The purpose of adding this driver is to get better time keeping
accuracy over the default MTU2 clocksource timer.
