Subject: [PATCH v8 24/42] ARM: davinci: dm365: add new clock init using common clock framework
Date:   Thu, 15 Mar 2018 21:52:40 -0500
Message-Id: <1521168778-27236-25-git-send-email-david@lechnology.com>
In-Reply-To: <1521168778-27236-1-git-send-email-david@lechnology.com>
References: <1521168778-27236-1-git-send-email-david@lechnology.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This adds the new board-specific clock init in mach-davinci/dm365.c
using the new common clock framework drivers.

The #ifdefs are needed to prevent compile errors until the entire
ARCH_DAVINCI is converted.

Also clean up the #includes since we are adding some here.
