Hi,

Yeah, i thought you might have meant that :-)

i m starting to think that the uartclk parameter that i pass to the
platform_add_devices function might be wrong --

i m passing the standard value of 1843200 for a baudrate of 115200...

now the output after the board specific encm3_platform_init function is
called, is the kernel messages with mostly alternate characters missing,
like so:

Could there be another cause for this?
This is my platform_device structure:
