Subject: hwmon: Define a standard interface for chassis intrusion detection
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=ec19920944246b4686c7772a58507a20c361dc9d;p=linux-2.6-omap-h63xx.git

hwmon: Define a standard interface for chassis intrusion detection

Define a standard interface for the chassis intrusion detection feature
some hardware monitoring chips have. Some drivers have custom sysfs
entries for it, but a standard interface would allow integration with
user-space (namely libsensors.)
