Subject: [PATCH] mxl-gpy: control LED reg from DT
|
|
|
|
Add dynamic configuration for the LED control registers on MXL PHYs.
|
|
|
|
This patch has been tested with MaxLinear GPY211C. It is unlikely to be
|
|
accepted upstream, as upstream plans on integrating their own framework
|
|
for handling these LEDs.
|
|
|
|
For the time being, use this hack to configure PHY driven device-LEDs to
|
|
show the correct state.
|
|
|
|
A possible alternative might be to expose the LEDs using the kernel LED
|
|
framework and bind it to the netdevice. This might also be upstreamable,
|
|
although it is a considerable extra amount of work.
