This picks up a series sent by Anton Bondarenko last year. It contains the remaining not yet upstreamed patches from Antons series plus some more DMA related cleanup patches. My mission was to hunt a bug in the DMA code path sometimes causing an additional word in the RX FIFO which locked up the driver in the next transfer. It turned out that this was no bug in the driver but instead in the device tree: We used the wrong SDMA script for i.MX6. The ECSPI cores are connected through the SPBA, so according to the reference manual we need the shp/mcu scripts rather than the app/mcu scripts.
Are you talking about what is known as "TKT238285 hardware issue" https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/spi/spi-imx.c?id=a02bb401f8ae264be782ee57d98bdd99f14c8022 ? Or are you talking about a different issue?
