Subject: apm821xx: add drivetemp sensor for the WD MyBook Series
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=01fe7a2b64091786b6518025641f17c725a7769b;p=openwrt%2Fstaging%2Fadrian.git

apm821xx: add drivetemp sensor for the WD MyBook Series

This patch adds the hwmon-drivetemp to the device.
It also adds device-tree bindings. This can be useful to
automate external fans which can be controlled for example
by either an unused sata-port or by the usb-power regulator.
