+Binding for a ST multiplexed clock driver.
+
+This binding supports only simple indexed multiplexers, it does not
+support table based parent index to hardware value translations.
+
+This binding uses the common clock binding[1].

+Required properties:

+- compatible : shall be:
+	"st,stih416-clkgenc-vcc-hd",	"st,clkgen-mux"
+	"st,stih416-clkgenf-vcc-fvdp",	"st,clkgen-mux"

+
+
+- #clock-cells : from common clock binding; shall be set to 0.
+
+- reg : A Base address and length of the register set.
+
+- clocks : from common clock binding

Documentation/devicetree/bindings/clock/st/st,clkgen-vcc.txt

+Binding for a type of STMicroelectronics clock crossbar (VCC).
+
+The crossbar can take up to 4 input clocks and control up to 16
+output clocks. Not all inputs or outputs have to be in use in a
+particular instantiation. Each output can be individually enabled,
+select any of the input clocks and apply a divide (by 1,2,4 or 8) to
+that selected clock.
+
+This binding uses the common clock binding[1].

+Required properties:
+
+- compatible : shall be:
+	"st,stih416-clkgenc",		"st,vcc"
+	"st,stih416-clkgenf",		"st,vcc"
+
+- #clock-cells : from common clock binding; shall be set to 1.
+
+- reg : A Base address and length of the register set.
+
+- clocks : from common clock binding
+
+- clock-output-names : From common clock binding. The block has 16
+                       clock outputs but not all of them in a specific instance
+                       have to be used in the SoC. If a clock name is left as
+                       an empty string then no clock will be created for the
+                       output associated with that string index. If fewer than
+                       16 strings are provided then no clocks will be created
+                       for the remaining outputs.
