+* Renesas CPG DIV6 Clock
+
+The CPG DIV6 clocks are variable factor clocks provided by the Clock Pulse
+Generator (CPG). Their clock input is divided by a configurable factor from 1
+to 64.
+
+Required Properties:
+
+ - compatible: Must be one of the following
+ - "renesas,r8a73a4-div6-clock" for R8A73A4 (R-Mobile APE6) DIV6 clocks
+ - "renesas,r8a7740-div6-clock" for R8A7740 (R-Mobile A1) DIV6 clocks
+ - "renesas,r8a7790-div6-clock" for R8A7790 (R-Car H2) DIV6 clocks
+ - "renesas,r8a7791-div6-clock" for R8A7791 (R-Car M2-W) DIV6 clocks
+ - "renesas,r8a7793-div6-clock" for R8A7793 (R-Car M2-N) DIV6 clocks
+ - "renesas,r8a7794-div6-clock" for R8A7794 (R-Car E2) DIV6 clocks
+ - "renesas,sh73a0-div6-clock" for SH73A0 (SH-Mobile AG5) DIV6 clocks
+ and "renesas,cpg-div6-clock" as a fallback.
+ - reg: Base address and length of the memory resource used by the DIV6 clock
+ - clocks: Reference to the parent clock(s); either one, four, or eight
+ clocks must be specified. For clocks with multiple parents, invalid
+ settings must be specified as "<0>".
+ - #clock-cells: Must be 0
+
+
+Optional Properties:
+
+ - clock-output-names: The name of the clock as a free-form string
+
+
+Example
+-------
+
+ sdhi2_clk: sdhi2_clk@e615007c {
+ compatible = "renesas,r8a73a4-div6-clock", "renesas,cpg-div6-clock";
+ reg = <0 0xe615007c 0 4>;
+ clocks = <&pll1_div2_clk>, <&cpg_clocks R8A73A4_CLK_PLL2S>,
+ <0>, <&extal2_clk>;
+ #clock-cells = <0>;
+ clock-output-names = "sdhi2ck";
