Subject: [PATCH v6 14/41] clk: davinci: Add platform information for TI DM365 PSC
Date:   Sat, 20 Jan 2018 11:13:53 -0600
Message-Id: <1516468460-4908-15-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 platform-specific declarations for the PSC clocks on TI
DM365 based systems.
