[PATCH] serial: qcom_geni_serial: use DT aliases according to DT bindings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Device tree bindings do not specify "hsuart" aliases, instead all serial
ports should use "serial" alias name as noted by Rob Herring [1].
Make qcom_geni_serial driver use "serial" alias and fallback to "hsuart"
if one is not found.
