Subject: [PATCH 1/6] [media] ddbridge: fix gap handling
Date: Sun, 20 Aug 2017 12:41:09 +0200	[thread overview]
Message-ID: <20170820104114.6515-2-d.scheller.oss@gmail.com> (raw)
In-Reply-To: <20170820104114.6515-1-d.scheller.oss@gmail.com>

From: Daniel Scheller <d.scheller@gmx.net>

Force gap setting if given by attribute and enable gap for older regmaps.
Also, setting a gap value of 128 via sysfs will now disable gap.
