Cover letter [PATCH RFC 0/7] DMA: S3C64XX: Conversion to the new channel request API
Quoted 20 lines · Sylwester Nawrocki

This patch series aims to convert the s3c64xx platform to use the new universal DMA channel request API, i.e. this is only meaningful for non-dt systems using s3c64xx SoCs.

I'm sending the whole series as RFC since I didn't test it yet, I'm going to prepare smd6410 for testing this series. It would be great if someone else could also test it, either SPI or sound functionality verification would be useful.

Then we could queue the first two patches in this series for v4.10-rc1 and the remaining patches for subsequent release.

The whole series can be pulled from git repository:
git://linuxtv.org/snawrocki/samsung.git
branch: for-v4.10/dma/pl080-s3c64xx

Thanks.

fields

Hmm... fixing the bug I mentioned in my other email this still seems to cause some problems with my SPI on Cragganmore:

[  200.210213] wm0010 spi0.0: I/O Error: rx-1 tx-1 res:rx-f tx-f len-2632
[  200.211275] wm0010 spi0.0: SPI transfer failed: -5

I am still looking into it, without your patches work the wm0010 comes up. A few other small things seem to have been broken in mainline since last time I fired up this board as well which is slowing me down a little (network seems to have stopped coming up and one of the regulators on the SD card is spamming me with warnings).

Thanks,
Charles
