Subject: [PATCHv2 1/4] lis3lv02d: DT: use s32 to support negative values
Date: Fri, 27 Mar 2015 15:39:43 +0100	[thread overview]
Message-ID: <1427467186-9360-2-git-send-email-sre@kernel.org> (raw)
In-Reply-To: <1427467186-9360-1-git-send-email-sre@kernel.org>

st,axis-{x,y,z} can be negative to imply inverted
axis.

Apart from that the minimal and maximal threshold
may be negative.
