AR934x chips also got the 'old' qca,ar9330-uart in addition to the 'new' ns16550a compatible one. Add device-tree bindings in ar934x.dtsi to make use of it. Reported-by: Piotr Dymacz <pepe2k@gmail.com> Signed-off-by: Daniel Golle <daniel@makrotopia.org> --- Unfortunately this doesn't work yet, I suspect a clock output doesn't get enabled. Symptoms are that the uart probes and the first echo Hallo World > /dev/ttyATH1 returns (but the characters are not actually outputted), doing that again will not return but wait forever. Any hints would be more than welcome :) target/linux/ath79/dts/ar934x.dtsi | 15 +++++++++++++++ 1 file changed, 15 insertions(+)
