| * 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> |

| 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>; |
