Subject: [Patch 1/3] ARM: dts: am43xx: add support for clkout1 clock
Date: Wed, 16 Oct 2019 13:49:52 -0500	[thread overview]
Message-ID: <20191016184954.14048-2-bparrot@ti.com> (raw)
In-Reply-To: <20191016184954.14048-1-bparrot@ti.com>

From: Tero Kristo <t-kristo@ti.com>

clkout1 clock node and its generation tree was missing. Add this based
on the data on TRM and PRCM functional spec.

commit 664ae1ab2536 ("ARM: dts: am43xx: add clkctrl nodes") effectively
reverted this commit 8010f13a40d3 ("ARM: dts: am43xx: add support for
clkout1 clock") which is needed for the ov2659 camera sensor clock
definition hence it is being re-applied here.

Fixes: 664ae1ab2536 ("ARM: dts: am43xx: add clkctrl nodes")
