Binding for a ST divider and multiplexer clock driver.

This binding uses the common clock binding[1].
Base address is located to the parent node. See clock binding[2]

Required properties:

- compatible : shall be:
	"st,clkgena-divmux-c65-hs",	"st,clkgena-divmux"
	"st,clkgena-divmux-c65-ls",	"st,clkgena-divmux"
	"st,clkgena-divmux-c32-odf0",	"st,clkgena-divmux"
	"st,clkgena-divmux-c32-odf1",	"st,clkgena-divmux"
	"st,clkgena-divmux-c32-odf2",	"st,clkgena-divmux"
	"st,clkgena-divmux-c32-odf3",	"st,clkgena-divmux"

- #clock-cells : From common clock binding; shall be set to 1.

- clocks : From common clock binding

- clock-output-names : From common clock binding.

Example:

	clockgenA@fd345000 {
		reg = <0xfd345000 0xb50>;

		CLK_M_A1_DIV1: CLK_M_A1_DIV1 {
			#clock-cells = <1>;
			compatible = "st,clkgena-divmux-c32-odf1",
				     "st,clkgena-divmux";

			clocks = <&CLK_M_A1_OSC_PREDIV>,
				 <&CLK_M_A1_PLL0 1>, /* PLL0 PHI1 */
				 <&CLK_M_A1_PLL1 1>; /* PLL1 PHI1 */

			clock-output-names = "CLK_M_RX_ICN_TS",
					     "CLK_M_RX_ICN_VDP_0",
					     "", /* Unused */
					     "CLK_M_PRV_T1_BUS",
					     "CLK_M_ICN_REG_12",
					     "CLK_M_ICN_REG_10",
					     "", /* Unused */
					     "CLK_M_ICN_ST231";
		};
