Merge tag 'omap-for-v4.14/debug-ll-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc

Pull "Updates to for omap debug_ll code to use generic DEBUG_UART_8250 code" from Tony Lindgren:

The legacy code to try to detect the debug_ll uart based on machine
is no longer needed, and we can remove it. Note that the Kconfig
options stay the same, we just need to define the port configuration
now.
