Subject: [PATCH 00/15] serial: qcom-geni-serial: implement support for SE DMA

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

The goal of this series is to update the qcom-geni-serial driver to use
the DMA mode of the QUPv3 serial engine. This is accomplished by the last
patch in the series. The previous ones contain either various tweaks,
reworks and refactoring or prepare the driver for adding DMA support.

More work will follow on the serial engine in order to reduce code
redundancy among its users and add support for SE DMA to the qcom GENI
SPI driver.

Bartosz Golaszewski (15):
  tty: serial: qcom-geni-serial: drop unneeded forward definitions
  tty: serial: qcom-geni-serial: remove unused symbols
  tty: serial: qcom-geni-serial: align #define values
  tty: serial: qcom-geni-serial: simplify the to_dev_port() macro
  tty: serial: qcom-geni-serial: remove stray newlines
  tty: serial: qcom-geni-serial: refactor qcom_geni_serial_isr()
  tty: serial: qcom-geni-serial: remove unneeded tabs
  tty: serial: qcom-geni-serial: split out the FIFO tx code
  tty: serial: qcom-geni-serial: drop the return value from handle_rx
  tty: serial: qcom-geni-serial: use of_device_id data
  tty: serial: qcom-geni-serial: stop operations in progress at shutdown
  tty: serial: provide devm_uart_add_one_port()
  tty: serial: qcom-geni-serial: use devres for uart port management
  soc: qcom-geni-se: add more symbol definitions
  tty: serial: qcom-geni-serial: add support for serial engine DMA
