Subject: lis3lv02d: DT: use s32 to support negative values
X-Git-Tag: v4.1-rc1~60^2~4
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=cdcd6f824ecb6b5e5fd6729c2552c1254012c3ca;p=linux.git

lis3lv02d: DT: use s32 to support negative values

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

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