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.
