Subject: [PATCH 1/4] net: phy: support 'active-high' property for PHY LEDs
|
|
|
|
In addition to 'active-low' and 'inactive-high-impedance' also
|
|
support 'active-high' property for PHY LED pin configuration.
|
|
As only either 'active-high' or 'active-low' can be set at the
|
|
same time, WARN and return an error in case both are set.
