Care to describe what > goes wrong so that can be added to the patch description? I tested this patch on sk-am62-lp on the upstream kernel and on the latest ti-sdk 6.1 kernel. With the ti-sdk 6.1 kernel I get mbox timeouts if the driver resets the ti-sysc. If it doesn't reset it, everything works on ti-sdk 6.1 as expected as well including wakeup from the wkup_uart0.
