Full DT-support is still a bit away for bcm63xx, as there are some nasty dependencies (conversion to a common-clock driver, adding a pinmux driver, resolving the issue that some chips require gpio directions configured even for !gpio-functions, conversion to gpiolib, making !OF-devices requiring gpios to use named gpios, ...). > I'm not interested in brcm63xx and don't have any such hardware flying > around.

There is no reason for not supporting both, so feel free to submit patches.
