The following patchset provides corrections for PIO-mode and support for DMA transfers in sun6i SPI driver.
Changes in v2: 1) Fixed issue with misplacing a piece of code that requires access to the transfer structure into sun6i_spi_prepare_message() function where the transfer structure is not available.
2) Fixed issue with passing an invalid argument into devm_request_irq() function.
Changes in v3: 1) Restored processing of 3/4 FIFO full interrupt.
2) Debug log enhancements.
Sergey Suloev (6): spi: sun6i: coding style/readability improvements spi: sun6i: handle chip select polarity flag spi: sun6i: restrict transfer length in PIO-mode spi: sun6i: use completion provided by SPI core spi: sun6i: introduce register set/unset helpers spi: sun6i: add DMA transfers support
