Required root node property: compatible="stericsson,u300"; Required node: syscon This contains the system controller. - compatible: must be "stericsson,u300-syscon". - reg: the base address and size of the system controller. Boards with the U300 SoC include: S365 "Small Board U365": Required node: s365 This contains the board-specific information. - compatible: must be "stericsson,s365". - vana15-supply: the regulator supplying the 1.5V to drive the board. - syscon: a pointer to the syscon node so we can access the syscon registers to set the board as self-powered. Example: / { model = "ST-Ericsson U300"; compatible = "stericsson,u300"; #address-cells = <1>; #size-cells = <1>; s365 { compatible = "stericsson,s365"; vana15-supply = <&ab3100_ldo_d_reg>; syscon = <&syscon>; }; syscon: syscon@c0011000 { compatible = "stericsson,u300-syscon"; reg = <0xc0011000 0x1000>; }; }; |
