+* 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>
+
+conn_lpcg: clock-controller@5b200000 {
+ compatible = "fsl,imx8qxp-lpcg-conn";
+ reg = <0x5b200000 0xb0000>;
+ #clock-cells = <1>;
+};
+
+usdhc1: mmc@5b010000 {
+ compatible = "fsl,imx8qxp-usdhc", "fsl,imx7d-usdhc";
+ interrupt-parent = <&gic>;
+ interrupts = <GIC_SPI 232 IRQ_TYPE_LEVEL_HIGH>;
+ reg = <0x5b010000 0x10000>;
+ clocks = <&conn_lpcg IMX8QXP_CONN_LPCG_SDHC0_IPG_CLK>,
+ <&conn_lpcg IMX8QXP_CONN_LPCG_SDHC0_PER_CLK>,
+ <&conn_lpcg IMX8QXP_CONN_LPCG_SDHC0_HCLK>;
