[PATCH v2] dmaengine: bcm2835: Add slave dma support
kernel at martin.sperl.org
Sun May 3 23:59:09 PDT 2015
I did tests with the (almost) finished dma-support of spi-bcm2835
against a TFT device and it work fine there.
Upstreaming this spi-bcm2835 patch obviously requires that the DMA
support is in the dma-engine driver first...
Please also see prior note about unnecessary interrupts when none
are requested for possible improvements.
