-* NXP i.MX8QXP LPCG (Low-Power Clock Gating) Clock bindings
-
-The Low-Power Clock Gate (LPCG) modules contain a local programming
-model to control the clock gates for the peripherals. An LPCG module
-is used to locally gate the clocks for the associated peripheral.
-
-Note:
-This level of clock gating is provided after the clocks are generated
-by the SCU resources and clock controls. Thus even if the clock is
-enabled by these control bits, it might still not be running based
-on the base resource.
-
-Required properties:
-- compatible: Should be one of:
- "fsl,imx8qxp-lpcg-adma",
- "fsl,imx8qxp-lpcg-conn",
- "fsl,imx8qxp-lpcg-dc",
- "fsl,imx8qxp-lpcg-dsp",
- "fsl,imx8qxp-lpcg-gpu",
- "fsl,imx8qxp-lpcg-hsio",
- "fsl,imx8qxp-lpcg-img",
- "fsl,imx8qxp-lpcg-lsio",
- "fsl,imx8qxp-lpcg-vpu"
-- reg: Address and length of the register set
-- #clock-cells: Should be <1>
-
-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

-Examples:
-
-#include <dt-bindings/clock/imx8qxp-clock.h>
