Subject: net: dsa: qca8k: add support for pws config reg
|
|
|
|
Some qca8327 switch require to force the ignore of power on sel
|
|
strapping. Some switch require to set the led open drain mode in regs
|
|
instead of using strapping. While most of the device implements this
|
|
using the correct way using pin strapping, there are still some broken
|
|
device that require to be set using sw regs.
|
|
Introduce a new binding and support these special configuration.
|
|
As led open drain require to ignore pin strapping to work, the probe
|
|
fails with EINVAL error with incorrect configuration.
