Well there is a pending rework of these optional peripherals for sam9x5
series. So we may end-up with this usart3 declaration in a separated
file that will be included in both sam9g25 and sam9x25 product
descriptions (together with the already existing pinctrl declaration
that resides in at91sam9x5.dtsi).
So, I keep your code and will try to make sure that it is included
during the move to that model. If you do not see it appearing, please
remind us then...
Thanks a lot, bye,
