Subject: [PATCH v4 0/5] LiteX SoC controller and LiteUART serial driver

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 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
