 Hello!

 In order to achieve this effect, i believe, it's not enough to fail SROMc probe. Peripherials (such as smsc) should then be
declared as subnodes.
 There's one problem with this, however. I could not manage to do it. If i place device's node inside of SROMc node, it does not get
probed at all, and i don't really understand why. I tried to read the code and i suggest that only specific devices (like
compatible="simple-bus") are searched for sub-devices.
 OTOH, this patch (http://www.spinics.net/lists/arm-kernel/msg449703.html) perfectly worked, and generic timer node placed inside of
MCT node was perfectly probed by the kernel. So i still don't understand why i could not place smsc description inside of SROMc.
 May be you can help me with this?
