[PATCH 0/8 v5] k3dma patches to add support for hi3660/HiKey960

[John Stultz]

This patch series is based on recent work by Tanglei Han, and
adds support for hi3660 SoCs as found on the HiKey960 board,
along with a few patches I've been carrying.

thanks
-john

New in v5:
* Minor typo fixes, minor rework to use BIT() macros

[PATCH 8/8 v5] arm64: dts: hi3660: Fixup unofficial dma-min-chan to dma-channel-mask

[John Stultz]

A undocumented and unimplemented binding got into the hi3660
dtsi, and this switches that binding to the now documented one.

Applied and fixed the minor style issues in patch 5, and retagged 3 thru
5 to dmaengine: xxx, thanks

My apologies for the style mistake. Your help is very much appreciated
here! Thanks so much again!

Just to clarify, are you planning on taking the reviewed binding
documents (patches 1&2) via your tree?

thanks

No issues it was a minor one so didnt warrant a respin!

yes sorry I should have clarified since this is multi-subsystem series.
I have applied 1 thru 5 that includes DT binding. I do that typically
for dmaengine driver patches with Rob's ack.

Thanks
