The patch titled Blackfin SPI Driver: tweak magic spi dma sequence to get it working on BF54x has been removed from the -mm tree. Its filename was blackfin-spi-driver-tweak-magic-spi-dma-sequence-to-get-it-working-on-bf54x.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: Blackfin SPI Driver: tweak magic spi dma sequence to get it working on BF54x From: Mike Frysinger <vapier.adi@xxxxxxxxx> Without this change, SPI DMA is not reliably under stress tests. Obiviously it's a hardware issue which is not addressed by any document.
