Subject: [PATCH Resend] Input: ads7846: Add description how to use internal reference (ADS7846)
Date: Mon, 29 Feb 2016 08:06:35 +0100 [thread overview]
Message-ID: <1456729595-32023-1-git-send-email-alexander.stein@systec-electronic.com> (raw)
By simply setting vref-mv to 0 the internal reference will be used.
Document that!
