This driver adds support for the Altera / Intel modular Scatter-Gather
Direct Memory Access (mSGDMA) intellectual property (IP) to the Linux
DMAengine subsystem. Currently it supports the following op modes:
- DMA_MEMCPY
- DMA_SG
- DMA_SLAVE
This implementation has been tested on an Altera Cyclone FPGA connected
via PCIe, both on an ARM and an x86 platform.
Applied, thanks
I am getting following warn and looking at code, I am not able to decide if
its harmless as a comment indicates reads maybe required.
drivers/dma/altera-msgdma.c: In function ‘msgdma_tasklet’:
drivers/dma/altera-msgdma.c:786:6: warning: variable ‘status’ set but not
used [-Wunused-but-set-variable]
u32 status;
^
drivers/dma/altera-msgdma.c:785:6: warning: variable ‘size’ set but not used
[-Wunused-but-set-variable]
u32 size;
^
Also there are bunch of sparse warns, please fix them up as well.
I'm on vacation for 2 weeks now and will get back to these
issues beginning of August. I hope this is okay.
Thanks,
Stefan
