Hmm with serdev you should not get /dev/ttyS0, so maybe you're missing:

CONFIG_SERIAL_DEV_BUS=y
CONFIG_SERIAL_DEV_CTRL_TTYPORT=y

Probably the Kconfig dependency should be for SERIAL_DEV_CTRL_TTYPORT
instead of SERIAL_DEV_BUS in these patches if that helps.

Or else you're missing the serdev related dts changes?
