[PATCH RFC 0/3] UART slave device support

Hi all, this patch series is our proposal to add hooks so that the driver for a device connected to an UART can monitor modem control lines and data activity of the connected chip. It contains an example for such a device driver which needs such sophisticated power control: wi2wi,w2sg0004 A rem
