Subject: [PATCH] cbus-tahvo: Add battery related register defines
Date: Sat, 26 Feb 2011 00:23:24 +0100 [thread overview]
Message-ID: <1298676204.27500.9.camel@marge> (raw)
This adds battery related register defines to the tahvo driver.
Signed-off-by: Michael Buesch <mb@bu3sch.de>

The knowledge originates from various reverse engineering efforts.
So naming might differ from the original unreleased documentation.
