Subject: [PATCH net-next v7 9/9] dt-bindings: net: mdio-gpio: add compatible for microchip,mdio-smi0

From: Michael Grzeschik <m.grzeschik@...gutronix.de>

Microchip SMI0 Mode is a special mode, where the MDIO Read/Write
commands are part of the PHY Address and the OP Code is always 0. We add
the compatible for this special mode of the bitbanged mdio driver.
