Subject: [net-next PATCH v4 1/4] dt-bindings: net: phy: Document new LEDs polarity property

Document new LEDs polarity property to define what mode the LED needs to
be put to turn it on.

Currently supported modes are:

- active-low
- active-high
- active-low-tristate
- active-high-tristate

Mode is optional and if it's not defined, a default value is chosed by
the driver.

Signed-off-by: Christian Marangi <ansuelsmth@...il.com>

Changes v4:
- Drop support for global active-low
- Rework to polarity option (for marvell10g series support)
Changes v3:
- Out of RFC
Changes v2:
- Add this patch
