If the patch goes in only for v4.11 it would be good to mark it for inclusion in v4.10 stable kernels. -- Thanks, Sylwester

You didn't mention any strict dependencies when sending this patch... What do you mean by "needing patch in v4.10"? Is the code already not bisectable? Already broken? Best regards, Krzysztof

Is the code already > not bisectable? Already broken? Yes, unfortunately on s3c2410, s3c2412 and s3c2443. I didn't notice when sending patches for the s3c24xx-iis and s3c2440-sdi drivers the dma_slave maps were only added for s3c2440 (commit 34681d84a0f7cc2 dmaengine: s3c24xx: Add dma_slave_map for s3c2440 devices) and not for remaining SoCs covered by these DMA client drivers.

Okay, so either entire pull goes into v4.10 or I will need a resend of this one patch with a little bit extended message why this is a v4.10 fix. BR, Krzysztof

These were sitting in the next for very long. Sorry for the delay. The patches in here are all straightforward, so I'm applying them for fixes now. Arnd
Hi, After our discussions about not-breaking out-of-tree DTB with SCU change in DeviceTree, I prepared an updated pull request without the questioned changes. Ten days ago I prepared a tag, pushed it... and apparently forgot to send pull request. At least, I don't have such email in my outbox. Dunno. So let's send it now, better late then never. With just few commits (without the DT SCU changes). These were sitting in the next for very long.
