1ST-Ericsson U300 Device Tree Bindings 2 3For various board the "board" node may contain specific properties 4that pertain to this particular board, such as board-specific GPIOs 5or board power regulator supplies. 6 7Required root node property: 8 9compatible="stericsson,u300"; 10 11Required node: syscon 12This contains the system controller. 13- compatible: must be "stericsson,u300-syscon". 14- reg: the base address and size of the system controller. 15 16Boards with the U300 SoC include: 17 18S365 "Small Board U365": 19 20Required node: s365 21This 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 28Example: 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}; 47
