Subject: [PATCH v1 1/5] ARM: mach-imx6q: do not select enet PTP clock source on QuadPlus
Date:   Sun, 12 Jul 2020 20:25:08 -0400
Message-Id: <20200713002512.28742-2-TheSven73@gmail.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

On QuadPlus, the enet PTP clock source is selected via the clocktree.
Therefore it should not be set in the machine layer (mach-imx6q).
