    1 ST-Ericsson U300 Device Tree Bindings
    2 
    3 For various board the "board" node may contain specific properties
    4 that pertain to this particular board, such as board-specific GPIOs
    5 or board power regulator supplies.
    6 
    7 Required root node property:
    8 
    9 compatible="stericsson,u300";
   10 
   11 Required node: syscon
   12 This contains the system controller.
   13 - compatible: must be "stericsson,u300-syscon".
   14 - reg: the base address and size of the system controller.
   15 
   16 Boards with the U300 SoC include:
   17 
   18 S365 "Small Board U365":
   19 
   20 Required node: s365
   21 This contains the board-specific information.
   22 - compatible: must be "stericsson,s365".
   23 - vana15-supply: the regulator supplying the 1.5V to drive the
   24   board.
   25 - syscon: a pointer to the syscon node so we can access the
   26   syscon registers to set the board as self-powered.
   27 
   28 Example:
   29 
   30 / {
   31         model = "ST-Ericsson U300";
   32         compatible = "stericsson,u300";
   33         #address-cells = <1>;
   34         #size-cells = <1>;
   35 
   36         s365 {
   37                 compatible = "stericsson,s365";
   38                 vana15-supply = <&ab3100_ldo_d_reg>;
   39                 syscon = <&syscon>;
   40         };
   41 
   42         syscon: syscon@c0011000 {
   43                 compatible = "stericsson,u300-syscon";
   44                 reg = <0xc0011000 0x1000>;
   45         };
   46 };
