Subject: [PATCH v2 0/4] spi: Fix DMA bugs in (not only) spi-s3c64xx
Date: Tue, 27 Sep 2022 13:21:13 +0200 [thread overview]
Message-ID: <20220927112117.77599-1-vincent.whitchurch@axis.com> (raw)
v2:
- Drop merged patch adding new test to spi-loopback-test
- Fix compiler warning in !HAS_DMA builds
- Add support to split transfers to core
This series fixes some bugs I found while running spi-loopback-test with
spi-s3c64xx. The first problem (which I actually noticed while trying to fix
the second problem with transfers >64KiB) seems to be a generic issue which
affects several drivers so I fixed it in the core.
The series has been tested on ARTPEC-8, which has a version of the IP similar
to Exynos 7 and with 64 byte FIFOs (compatible with "tesla,fsd-spi").
