| 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. |

| 7 | Required root node property: |

| Linus Walleij | cf0ce09 | 2013-05-22 16:15:13 +0200 | [diff] [blame] | 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. |

| 18 | S365 "Small Board U365": |
| 19 | |
| 20 | Required node: s365 |
| Linus Walleij | cf0ce09 | 2013-05-22 16:15:13 +0200 | [diff] [blame] | 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. |
| Masanari Iida | 9ca1839 | 2013-07-23 00:13:48 +0900 | [diff] [blame] | 25 | - syscon: a pointer to the syscon node so we can access the |
| Linus Walleij | cf0ce09 | 2013-05-22 16:15:13 +0200 | [diff] [blame] | 26 | syscon registers to set the board as self-powered. |
