This sounds great to me, merging the whole series through Shawn's imx tree would prevent issues in linux-next or possible bisect failures in 4.21. ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

Oops, I overlooked the notes in cover-letter. Let's use the approach as suggested there - applying the dts change after all driver dependencies are landed.

I do not know what you mean by "issues in linux-next" (I assume you mean when Shawn sends the patches to linux-next in preparation for v4.21); we have not planned any other PCI pull request for v4.20-rc1 material. > The patch already has reviewed-by tags so "merging it soon" is not > unreasonable. I can ACK it if Shawn wants to pull it, it may take a while to see it in -next if it has to go through the PCI tree, I think it is better to queue the series without splitting the patches across multiple channels though.

As mentioned in the cover letter this requires multi-PD support in imx-pci to be implemented, specifically PATCH 3/4 of this series: https://lore.kernel.org/patchwork/patch/996810/ Unless that also gets merged soon via pci I expect issues in linux-next. The patch already has reviewed-by tags so "merging it soon" is not unreasonable. Link to cover: https://lore.kernel.org/patchwork/cover/996807/ There is also an mxsfb dependency but that's already merged in torvalds/master. ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
