AM6548: WKUP_UART Input Clock Discrepancies

Part Number: AM6548

Tool/software:

Why is that WKUP_UART on the AM6548 has its input clock configured to 96 MHz ? Is this due to a sysfw issue?

We are having the same issue and resolution as this thread: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1231012/am6548-some-issues-about-wkup_uart0/4715172?tisearch=e2e-sitesearch&keymatch=am6548%252520wkup_uart#4715172

Why is it that we must configure WKUP_UART to 96 MHz for the baud rate not be double what we set the driver to (i.e. setting WKUP_UART baud to 115200 results in baud of 230400 on the wire). Is there some errata documented somewhere?

Thanks,
Ben
