+description:
+ i.MX BLK_CTL is a conglomerate of different GPRs that are
+ dedicated to a specific subsystem. Because it usually contains
+ clocks amongst other things, it needs access to the i.MX clocks
+ API. All the other functionalities it provides can work just fine
+ from the clock subsystem tree.
+
+properties:
+ compatible:
+ items:
+ - enum:
+ - fsl,imx8mp-audio-blk-ctl
+ - fsl,imx8mp-hdmi-blk-ctl
+ - fsl,imx8mp-media-blk-ctl
+ - const: syscon
+
+ reg:
+ maxItems: 1
+
+ power-domains:
+ maxItems: 1
+
+ '#clock-cells':
+ const: 1
+
+ '#reset-cells':
+ const: 1
+
+required:
+ - compatible
+ - reg
+ - power-domains
+ - '#clock-cells'
+ - '#reset-cells'
+
+additionalProperties: false
+
+examples:
+ - |
+ #include <dt-bindings/clock/imx8mp-clock.h>
+
+ audio_blk_ctl: clock-controller@30e20000 {
+ compatible = "fsl,imx8mp-audio-blk-ctl", "syscon";
+ reg = <0x30e20000 0x10000>;
