That last paragraph seems to say that Y and N are the only choices here. It can also be set to M ...

This patchset introduces support for LiteX SoC Controller and LiteUART - serial device from LiteX SoC builder (https://github.com/enjoy-digital/litex). In the following patchset I will add a new mor1kx-based (OpenRISC) platform that uses this device. Later I plan to extend this platform by adding support for more devices from LiteX suite. Changes in v7: - added missing include directive in UART's driver Changes in v6: - changed accessors in SoC Controller's driver - reworked UART driver Changes in v5: - added Reviewed-by tag - removed custom accessors from SoC Controller's driver - fixed error checking in SoC Controller's driver Changes in v4: - fixed copyright headers - fixed SoC Controller's yaml - simplified SoC Controller's driver Changes in v3: - added Acked-by and Reviewed-by tags - introduced LiteX SoC Controller driver - removed endianness detection (handled now by LiteX SoC Controller driver) - modified litex.h header - DTS aliases for LiteUART made optional - renamed SERIAL_LITEUART_NR_PORTS to SERIAL_LITEUART_MAX_PORTS - changed PORT_LITEUART from 122 to 123 Changes in v2: - binding description rewritten to a yaml schema file - added litex.h header with common register access functions Filip Kokosinski (3): dt-bindings: vendor: add vendor prefix for LiteX dt-bindings: serial: document LiteUART bindings drivers/tty/serial: add LiteUART driver Pawel Czarnecki (2): dt-bindings: soc: document LiteX SoC Controller bindings drivers/soc/litex: add LiteX SoC Controller driver .../bindings/serial/litex,liteuart.yaml | 38 ++ .../soc/litex/litex,soc-controller.yaml | 39 ++ .../devicetree/bindings/vendor-prefixes.yaml | 2 + MAINTAINERS | 9 + drivers/soc/Kconfig | 1 + drivers/soc/Makefile | 1 + drivers/soc/litex/Kconfig | 15 + drivers/soc/litex/Makefile | 3 + drivers/soc/litex/litex_soc_ctrl.c | 197 +++++++++ drivers/tty/serial/Kconfig | 31 ++ drivers/tty/serial/Makefile | 1 + drivers/tty/serial/liteuart.c | 405 ++++++++++++++++++ include/linux/litex.h | 45 ++ 13 files changed, 787 insertions(+) create mode 100644 Documentation/devicetree/bindings/serial/litex,liteuart.yaml create mode 100644 Documentation/devicetree/bindings/soc/litex/litex,soc-controller.yaml create mode 100644 drivers/soc/litex/Kconfig create mode 100644 drivers/soc/litex/Makefile create mode 100644 drivers/soc/litex/litex_soc_ctrl.c create mode 100644 drivers/tty/serial/liteuart.c create mode 100644 include/linux/litex.h
