[PATCH 1/9] dt-bindings: powerpc: Add binding for Freescale/NXP MPC83xx SoCs

J. Neuschäfer via B4 Relay

From: "J. Neuschäfer" <j.ne@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.
