Subject[PATCH v2 00/10] serial: st-asc: Allow handling of RTS line
Date
When hardware flow-control is disabled, manual toggling of the UART's
reset line (RTS) using userland applications (e.g. stty) is not
possible, since the ASC IP does not provide this functionality in the
same was as some other IPs do. Thus, we have to do this manually.

This set ensures the correct Pinctrl groups are configured and
obtained for both manual toggling of the RTS line and for the IP to
take over the lines when HW flow-control is requested by the user.

Lee Jones (10):
serial: st-asc: Ignore the parity error bit if 8-bit mode is enabled
serial: st-asc: Provide RTS functionality
serial: st-asc: Read in all Pinctrl states
serial: st-asc: (De)Register GPIOD and swap Pinctrl profiles
serial: st-asc: Use generic DT binding for announcing RTS/CTS lines
dt-bindings: serial: Update 'uart-has-rtscts' description
ARM: dts: STiH410-b2260: Identify the UART RTS line
ARM: dts: STiH407-pinctrl: Add Pinctrl group for HW flow-control
ARM: dts: STiH407-family: Use new Pinctrl groups
ARM: dts: STiH410-b2260: Enable HW flow-control
