Subject[PATCH v8 05/15] dt-bindings: power: Add fsl,scu-pd yaml file
Date
From: Abel Vesa <abel.vesa@nxp.com>

In order to replace the fsl,scu txt file from bindings/arm/freescale,
we need to split it between the right subsystems. This patch documents
separately the 'power controller' child node of the SCU main node.
