Subject: [PATCH 4/5] arm64: dts: allwinner: a64: Add pwm device
Date:   Mon, 12 Mar 2018 16:10:49 +0000
Message-Id: <20180312161050.7647-5-harald@ccbib.org>
In-Reply-To: <20180312161050.7647-1-harald@ccbib.org>
References: <20180312161050.7647-1-harald@ccbib.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This device is compatible with A13, so no new driver is needed.

I saw that Andre Przywara has been working on A64 pwm too and has
submitted some patches a few days ago. I think his patches are functionally
equivalent to this one here, but clean up things a bit and thus are
preferable. See:

https://groups.google.com/forum/#!topic/linux-sunxi/hQFeteP591k

I'm including my patch here mostly to have a consistent series for others
to test. OTOH you might merge the device tree changes here and pick up
the cleanup patches from him. Either way should work fine.
