This reverts commit 1820cd0. The spi-bcm2835 driver has been fixed, so now we can use it again. Signed-off-by: Noralf Trønnes <[email protected]>

Don't pull this yet, I have to change txbuflen to get good throughput. The dma mapping/engine overhead is high. |
Because of the spi dma mapping/engine overhead with spi-bcm2835, txbuflen has to be increased from 4096 to 32768 to maximize throughput (11MB/s at 128MHz). Signed-off-by: Noralf Trønnes <[email protected]>

Done updating PR. |
|
For the SPI DMA curious: For comparison, the out-of-tree spi-bcm2708 can do 12MB/s with 4k buffers, but relies on the legacy DMA API. |
