Subject: [net-next PATCH v10 1/5] dt-bindings: net: phy: Make LED active-low property common
Date: Thu, 25 Jan 2024 21:36:57 +0100

Move LED active-low property to common.yaml. This property is currently
defined multiple times by bcm LEDs. This property will now be supported
in a generic way for PHY LEDs with the use of a generic function.

With active-low bool property not defined, active-high is always
assumed.
