Subject: [PATCH 2/7] clocksource: sun4i: add a compatible for suniv
Date: Mon, 11 Feb 2019 12:21:08 +0300
Message-ID: <3de720ad1d2b47bf987fa56076d570de8043ed35.1549875778.git.mesihkilinc@gmail.com> (raw)
In-Reply-To: <cover.1549875778.git.mesihkilinc@gmail.com>

The suniv (new F-series) chip has a timer with less functionality than
the A10 timer, e.g. it has only 3 channels.

Add a new compatible for it. As we didn't use the extra channels on A10
either now, the code needn't to be changed.

The suniv chip is based on ARM926EJ-S CPU, thus it has no architecture timer.

Register sun4i_timer as sched_clock on it.
