Only very recent versions of U-Boot set the brg-frequency property, so you need
to check for situations where "*prop" is 0. If it is, then you need to take
the
QE's bus-frequency property and divide it by two. See my ucc_uart driver for
an
example.
And PowerPC-specific patches should not be cross-posted to linux-kernel.
