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"; | |
| 4d3ab5ec | 10 | |
| cf0ce095 LW |
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 | |
| cf0ce095 LW |
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. | |
| 9ca18397 | 25 | - syscon: a pointer to the syscon node so we can access the |
| cf0ce095 | 26 | syscon registers to set the board as self-powered. |
