One of the biggest roadblocks on the way of S3C64xx to DeviceTree support is its DMA driver, which is completely platform-specific and provides private API (s3c-dma), not even saying that its design is completely against multiplatform-awareness.
I tried to test this on my s3c64xx based system but it gave me a kernel that didn't boot far enough to give console output (there's some early init stuff that uses SPI...). That said, I needed:
diff --git a/drivers/dma/amba-pl08x.c b/drivers/dma/amba-pl08x.c index 210a893..0f49707 100644 --- a/drivers/dma/amba-pl08x.c +++ b/drivers/dma/amba-pl08x.c @@ -313,7 +313,7 @@ static int pl08x_request_mux(struct pl08x_dma_chan *plchan) int ret;
if (plchan->mux_use++ == 0 && pd->get_signal) { - ret = pd->get_signal(plchan->cd); + ret = (pd->get_signal)(plchan->cd); if (ret < 0) { plchan->mux_use = 0; return ret;
to get it to build which makes me suspect the compiler a bit as well... the system has audio, SPI and MMC enabled.
I was applying this to -next, are there any other dependencies I need or anything?
