[PATCH v5 03/14] dt-bindings: pinctrl: imx: Add fsl,scu-iomux yaml file

[Viorel Suman <viorel.suman@xxxxxxx>]

From: Abel Vesa <abel.vesa@xxxxxxx>

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 'iomux/pinctrl' child node of the SCU main node.
