Subject: [PATCH 22/39] fireworks: Add proc interface for debugging purpose
Date: Fri, 28 Feb 2014 12:27:35 +0900
Message-ID: <1393558072-25926-23-git-send-email-o-takashi@sakamocchi.jp> (raw)
In-Reply-To: <1393558072-25926-1-git-send-email-o-takashi@sakamocchi.jp>

This commit adds proc interface to output infomation for debugging.
 - firmware information
 - sampling rate and clock source
 - physical metering (linear value)
