Tomoya MORINAGA f3e03e2eb0 spi-topcliff-pch: Fix overrun issue ... We found that adding load, Rx data sometimes drops.(with DMA transfer mode) The cause is that before starting Rx-DMA processing, Tx-DMA processing starts. This causes FIFO overrun occurs. This patch fixes the issue by modifying FIFO tx-threshold and DMA descriptor size like below. Current this patch Rx-descriptor 4Byte+12Byte*341 --> 12Byte*340-4Byte-12Byte Rx-threshold (Not modified) Tx-descriptor 4Byte+12Byte*341 --> 16Byte-12Byte*340 Rx-threshold 12Byte --> 2Byte Signed-off-by: Tomoya MORINAGA <tomoya-linux@dsn.okisemi.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>		2011-10-04 10:10:50 -06:00
