For various board the "board" node may contain specific properties
|
|
|
|
|
that pertain to this particular board, such as board-specific GPIOs
|
|
|
|
|
or board power regulator supplies.

|
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.

|
|
|
|
|
|
Required node: s365
|
2013-05-22 14:15:13 +00:00
|
|
|
This contains the board-specific information.
|
|
|
|
|
- compatible: must be "stericsson,s365".
|
|
|
|
|
- vana15-supply: the regulator supplying the 1.5V to drive the
|
|
|
|
|
board.
|
2013-07-22 15:13:48 +00:00
|
|
|
- syscon: a pointer to the syscon node so we can access the
|
2013-05-22 14:15:13 +00:00
|
|
|
syscon registers to set the board as self-powered.
