I've got that coded up but I'm still testing it... If you want to try it too, you can find it at <https://chromium-review.googlesource.com/251341>. Note that without my patch I find that I _really_ need Addy's patch to make sure that the card isn't busy in setup_bus. With my patch Addy's code catches the card busy less often. I'm still trying to see if there's a way to totally remove the need for his setup_bus and still trying to grok all the patches flying around...Ah, this might be the magic needed: https://chromium-review.googlesource.com/251344 I think that together with the previous patch things are happy for me without any of Addy's patches, though it's the end of my work day and I haven't given this nearly as much testing as I'd like. I'll continue testing tomorrow and then post both patches together upstream.
OK, posted three patches upstream... A little hard to follow all the patches flying around (so I'll probably reply a few different places with the same info), but I believe that all of Addy's patches (with the exception of the one intended to fix mmc_test which needs to be spun by him for a bugfix) can be replaced with: * mmc: dw_mmc: Don't start commands while busy https://patchwork.kernel.org/patch/5858221/ * mmc: dw_mmc: Make sure we only adjust the clock when power is on https://patchwork.kernel.org/patch/5858261/ * mmc: dw_mmc: Give a good reset after we give power https://patchwork.kernel.org/patch/5858281/ In order to avoid further spreading info out among several patches, I'd request that you don't respond here but instead respond to my posted patches. Thanks! -Doug
