examples:
Other than described in commit c94d1783136 ("dt-bindings: net: phy: Make LED active-low property common") the absence of the 'active-low' property means not to touch the polarity settings which are inherited from reset defaults, the bootloader or bootstrap configuration. Hence, in order to override a LED pin being active-high in case of the default, bootloader or bootstrap setting being active-low an additional property 'active-high' is required. Document that property and make it mutually exclusive to the existing 'active-low' property.
