The theme of this series of patches is to try to allow running the eMMC at 150 MHz on the rk3399 SoC, though the changes should still be correct and have merit on their own. The motivation for running at 150 MHz is that doing so improves signal integrity and (with some eMMC devices) doesn't affect throughput. These patches have been structured to keep things as separate as possible, but nevertheless there are still some dependencies between patches. It probably makes the most sense for all of the non-device tree patches to go through a single tree. PHY patches now have Acks from Kishon so that means things should be clear for all non-DTS patches to go through the MMC tree if Ulf agrees. Device tree patches should be able to be landed separately and the worst what would happen is a warning in the kernel log if you have the code without the device tree. The code patches are based on Ulf's mmc-next. In v3 of the series I've pulled in the latest version of a previous PHY series posted by Brian Norris. The device tree patches are based on Heiko's v4.8-armsoc/dts64.
just so it doesn't get lost from v2->v3, I plan on picking up the dts patches 9 and 15 after the rest landed in the mmc tree - as they will only apply on top of my general dts branch. Heiko
