+Milbeaut M10V Clock Controller Binding
+----------------------------------------
+Milbeaut clock controller is consists of few oscillators, PLL, multiplexer
+and few divider modules
+
+This binding uses common clock bindings
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible: shall be "socionext,milbeaut-m10v-clk-regs"
+- reg: shall contain base address and length of clock registers
+- #clock-cells: shall be 0
+
+Example:
+ m10v-clk-tree@ {
+ compatible = "socionext,milbeaut-m10v-clk-regs";
+ reg = <0x1d021000 0x4000>;
+
+ clocks {
+ #address-cells = <0>;
+ #size-cells = <0>;
+
+ uclk40xi: uclk40xi {
+ compatible = "fixed-clock";
+ #clock-cells = <0>;
+ clock-frequency = <40000000>;
+ };
+ };
+ }
+
+The clock consumer shall specify the desired clock-output of the clock
+controller (as defined in [2]) by specifying output-id in its "clock"
+phandle cell
+[2] arch/arm/boot/dts/milbeaut-m10v-clk.h
+
+For example for UART1:
+ usio1: usio_uart@1e700010 {
+ index = <0>;
+ compatible = "socionext,milbeaut-m10v-usio-uart";
+ reg = <0x1e700010 0x10>;
+ interrupts = <0 141 0x4>, <0 149 0x4>;
+ interrupt-names = "rx", "tx";
+ clocks = <&hclk>;
+ };
+
+
+
+
+Required properties:
+- compatible:
+ "socionext,milbeaut-m10v-clk-mux"
+ -clock-cells: should be 0
+ -clocks: should be two factor
+ "socionext,milbeaut-m10v-pll-fixed-factor"
+ -clock-cells: should be 0
+ -clocks: should be one factor
+ -offset: offset
+ -clock-div: div number
+ -clock-mult: multiple number
+ "socionext,milbeaut-m10v-clk-div"
+ -clock-cells: should be 0
+ -clocks: should be one factor
+ -offset: offset
+ -mask: mask bit
+ -ratios: div ratio
+
+Example
+ piclk_mux_0: spiclk_mux_0 {
+ compatible = "socionext,m10v-clk-div";
+ #clock-cells = <0>;
+ clocks = <&pll10_div_1_2>;
+ offset = <bSPICLK>;
+ mask = <0x3>;
+ ratios = <4 0x5 2 0x4>;
+ };
+
+ pll10: pll10 {
+ compatible = "socionext,m10v-pll-fixed-factor";
+ #clock-cells = <0>;
+ clocks = <&uclk40xi>;
+ offset = <10>;
+ clock-div = <5>;
+ clock-mult = <108>;
+ };
+
+ emmcclk: emmcclk {
+ compatible = "socionext,m10v-clk-div";
+ #clock-cells = <0>;
+ clocks = <&pll11>;
+ offset = <bEMMCCLK>;
+ mask = <0x3>;
+ ratios = <15 0x7 10 0x6 9 0x5 8 0x4>;
+ };
