Subject: [RFC PATCH v4 09/17] clocksource: sun4i: add a compatible for suniv
Date:   Sun, 25 Nov 2018 10:43:12 +0300
Message-Id: <c7f0f45f5da8e8b1842e9b71380b0e39783db27b.1543131714.git.mesihkilinc@gmail.com>
In-Reply-To: <cover.1543131714.git.mesihkilinc@gmail.com>
References: <cover.1543131714.git.mesihkilinc@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
