Currently, .clk_bit_rate is not being set in init_serial_data for debug UART, but its then used uart_dm_init() and this breaks debug UART on IPQ40xx.
So, lets populate .clk_bit_rate for debug UART as well. IPQ40xx requires special value of 0xff, so set it if ARCH_IPQ40XX is selected, otherwise default to the same value that regular DM UART will use.
Ah, I have a patch lying around to configure this automatically, but didn't get around to sending it. Could you give it a test on your IPQ board if I send it your way?
Kind regards,
