Calling the devinfo against a device which is linked to some devicetree
node weill result a devictree dump of this node. For example:
barebox@Protonic PRTI6Q board:/ devinfo sound-spdif.of
Bus: platform
Device node: /sound-spdif
sound-spdif {
compatible = "fsl,imx-audio-spdif";
model = "imx-spdif";
spdif-controller = <0x7a>;
spdif-in;
spdif-out;
};
Calling same command on a device wich is linked to the root node of
devicetree, for example "machine.of", will trigger a dump fo complete
devicetree. Since the same functionality is provided by the "of_dump"
command, it is better to limit devinfo on the root device. After this
patch we would get following output:
barebox@Protonic PRTI6Q board:/ devinfo machine.of
Driver: board-protonic-imx6
Bus: platform
Parameters:
boardid: 0 (type: uint32)
boardrev: 1 (type: uint32)
In this example, "boardid" and "boardrev" are variabled provided by this
this specific board driver.
