Subject: [PATCH v2 00/15] serial: qcom-geni-serial: implement support for SE DMA
Date: Tue, 22 Nov 2022 11:21:10 +0100 [thread overview]
Message-ID: <20221122102125.142075-1-brgl@bgdev.pl> (raw)
From: Bartosz Golaszewski <bartosz.golaszewski@linaro.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.
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
