[PATCH v5 02/14] dt-bindings: clk: imx: Add fsl,scu-clk yaml file

From: Viorel Suman
Date: Thu Jun 16 2022 - 12:44:15 EST


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 'clock' child node of the SCU main node.

+description: i.MX SCU Client Device Node
+ Client nodes are maintained as children of the relevant IMX-SCU device node.
+ This binding uses the common clock binding.
+ (Documentation/devicetree/bindings/clock/clock-bindings.txt)
+ The clock consumer should specify the desired clock by having the clock
+ ID in its "clocks" phandle cell.
+ See the full list of clock IDs from
+ include/dt-bindings/clock/imx8qxp-clock.h
