/* DEVICE
|
|
|
|
trace - the properties of this dummy device specify trace options
|
|
|
|
DESCRIPTION
|
|
|
|
The properties of this device are used, during initialization, to
|
|
specify the value various simulation trace options. The
|
|
initialization can occure implicitly (during device tree init) or
|
|
explicitly using this devices ioctl method.
|
|
|
|
The actual options and their default values (for a given target)
|
|
are defined in the file debug.
|
|
|
|
This device is normally a child of the /openprom node.
|
|
|
|
EXAMPLE
|
|
|
|
The trace option dump-device-tree can be enabled by specifying the
|
|
option:
|
|
|
|
| -o '/openprom/trace/dump-device-tree 0x1'
|
|
|
|
Alternativly the shorthand version:
|
|
|
|
| -t dump-device-tree
|
|
|
|
can be used. */
