From: "J. Neuschäfer" <j...@posteo.net> Add a new binding for MPC83xx platforms, describing the board compatible strings used in currently existing device trees.
Note that the SoC bus is called immr@... in many existing devicetrees, but this contradicts the simple-bus binding. Reviewed-by: Rob Herring (Arm) <r...@kernel.org> Signed-off-by: J.
