Subject: [PATCH net-next v2 1/4] dt-bindings: net: Add aspeed,ast2600-mdio binding
Date: Wed, 31 Jul 2019 15:09:56 +0930 [thread overview]
Message-ID: <20190731053959.16293-2-andrew@aj.id.au> (raw)
In-Reply-To: <20190731053959.16293-1-andrew@aj.id.au>
The AST2600 splits out the MDIO bus controller from the MAC into its own
IP block and rearranges the register layout. Add a new binding to
describe the new hardware.
Signed-off-by: Andrew Jeffery <andrew@aj.id.au>

v2:
* aspeed: Utilise mdio.yaml
* aspeed: Drop status from example
