Subject: [PATCH] net: phy: mediatek-ge: add LED configuration interface
|
|
|
|
This adds a small hack similar to the one used for ar8xxx switches to
|
|
read a reg:value map for configuring the LED configuration registers.
|
|
|
|
This allows OpenWrt to write device-specific LED action as well as blink
|
|
configurations. It is unlikely to be accepted upstream, as upstream
|
|
plans on integrating their own framework for handling these LEDs.
|
|
