-Subject: [PATCH 1/2] power: reset: linkstation-poweroff: prepare for new
- devices
-
-This commit prepare driver for another device support.
-
-New power_off_cfg structure describes two most important things: name of
-mdio bus and pointer to register setting function. It allow to add new
-device with different mdio bus node and other phy register config.
