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. v2 -> v3: - drop devres patches from the series v1 -> v2: - turn to_dev_uport() macro into a static inline function - use CIRC_CNT_TO_END() and uart_xmit_advance() where applicable and don't handle xmit->tail directly - drop sizeof() where BYTES_PER_FIFO_WORD can be used - further refactor qcom_geni_serial_handle_tx_fifo() - collect review tags Bartosz Golaszewski (13): 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: improve 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: refactor qcom_geni_serial_handle_tx() 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 soc: qcom-geni-se: add more symbol definitions tty: serial: qcom-geni-serial: add support for serial engine DMA drivers/tty/serial/qcom_geni_serial.c | 606 +++++++++++++++++--------- include/linux/qcom-geni-se.h | 3 + 2 files changed, 409 insertions(+), 200 deletions(-)
