2010-03-03DMAENGINE: COH 901 318 lli sg offset fixLinus Walleij1-4/+6
This makes the COH 901 318 respect the scatter offset field by using the sg_phys() rather than the sg_dma_address() so we get a pointer to the actual data we want to send rather than the beginning of the buffer. Also initialize the lli:s a bit more thoroughly. Signed-off-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2010-03-03DMAENGINE: COH 901 318 remove irq countingLinus Walleij1-10/+3
This removes the pointless irq counting for the COH 901 318, as it turns out the hardware will only ever fire one IRQ for a linked list anyway. In the process also a missing spinlock was introduced.
