+Required properties:
+- compatible : shall be one of the following:
+	"zte,zx296702-topcrm":
+		zx296702 top clock selection, divider and gating
+
+	"zte,zx296702-lsp0crpm" or

+- reg: Address and length of the register set

+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell. See include/dt-bindings/clock/imx5-clock.h
+for the full list of i.MX5 clock IDs.
