Subject: [PATCH v3 5/5] ARM: davinci: remove clock debugfs
Date: Fri,  8 Dec 2017 20:15:11 -0600	[thread overview]
Message-ID: <1512785711-15064-6-git-send-email-david@lechnology.com> (raw)
In-Reply-To: <1512785711-15064-1-git-send-email-david@lechnology.com>

This removed the debugfs entry for mach-davinci clocks. The clocks now use
the common clock framework, which provides debugfs already, so this code is
redundant.
