2023-09-11spi: stm32: add a delay before SPI disableValentin Caron
As explained in errata sheet, in section "2.14.5 Truncation of SPI output signals after EOT event": On STM32MP1x, EOT interrupt can be thrown before the true end of communication. So we add a delay of a half period to wait the real end of the transmission.

The patch to reduce DMA RX to single byte width all the time is *hopefully* excessively cautious but it's unclear which SoCs are affected so the fix just covers everything for safety" * tag 'spi-fix-v6.6-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: spi: sun6i: fix race between DMA RX transfer completion and RX FIFO drain spi: sun6i: reduce DMA RX transfer width to single byte
2023-09-04spi: sun6i: fix race between DMA RX transfer completion and RX FIFO drainTobias Schramm
Previously the transfer complete IRQ immediately drained to RX FIFO to read any data remaining in FIFO to the RX buffer. This behaviour is correct when dealing with SPI in interrupt mode. However in DMA mode the transfer complete interrupt still fires as soon as all bytes to be transferred have been stored in the FIFO. At that point data in the FIFO still needs to be picked up by the DMA engine. Thus the drain procedure and DMA engine end up racing to read from RX FIFO, corrupting any data read. Additionally the RX buffer pointer is never adjusted according to DMA progress in DMA mode, thus calling the RX FIFO drain procedure in DMA mode is a bug. Fix corruptions in DMA RX mode by draining RX FIFO only in interrupt mode. Also wait for completion of RX DMA when in DMA mode before returning to ensure all data has been copied to the supplied memory buffer.

2023-09-04spi: sun6i: reduce DMA RX transfer width to single byteTobias Schramm
Through empirical testing it has been determined that sometimes RX SPI transfers with DMA enabled return corrupted data. This is down to single or even multiple bytes lost during DMA transfer from SPI peripheral to memory. It seems the RX FIFO within the SPI peripheral can become confused when performing bus read accesses wider than a single byte to it during an active SPI transfer. This patch reduces the width of individual DMA read accesses to the RX FIFO to a single byte to mitigate that issue.

2023-08-22spi: switch to use modern name (part4)Mark Brown
Merge series from Yang Yingliang <yangyingliang@huawei.com>: I'm trying to rename the legacy name to modern name used in SPI drivers, this is part4 patchset. After introducing devm_spi_alloc_host/spi_alloc_host(), the legacy named function devm_spi_alloc_master/spi_alloc_master() can be replaced. And also change other legacy name master/slave to modern name host/target or controller. Each patch compile test passed.
