Subject: [PATCH v6 41/41] ARM: dts: da850: Add clocks
Date:   Sat, 20 Jan 2018 11:14:20 -0600
Message-Id: <1516468460-4908-42-git-send-email-david@lechnology.com>
In-Reply-To: <1516468460-4908-1-git-send-email-david@lechnology.com>
References: <1516468460-4908-1-git-send-email-david@lechnology.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This adds clock provider nodes for da850 and wires them up to all of the
devices.

Signed-off-by: David Lechner <david@lechnology.com>
---

v6 changes:
- updated for device tree bindings changes earlier in this series
- use single async2 clock instead of duplicate fixed factor clocks
- add clock-names property to mdio node
