Subject: [PATCH v2 0/2] clocksource: Add renesas-ostm timer driver
Date: Fri, 20 Jan 2017 16:20:01 -0500 [thread overview]
Message-ID: <20170120212003.4103-1-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.
v2:
* The biggest change was now the channels are independent of each
other and have separate nodes in the DT. The first probed will
be set up as a clock source, and any additional channels probed
will become a clock event.
