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. If others agree, perhaps the most sane would be to get Acks from PHY maintainers and then to land the patches in the MMC tree. 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, then 4 patches that are outstanding / ready to land. Specifically: - https://patchwork.kernel.org/patch/9086501/ phy: rockchip-emmc: give DLL some extra time to be ready - https://patchwork.kernel.org/patch/9093681/ phy: rockchip-emmc: configure frequency range and drive impedance - https://patchwork.kernel.org/patch/9086511/ phy: rockchip-emmc: configure default output tap delay - https://patchwork.kernel.org/patch/9086531/ phy: rockchip-emmc: reindent the register definitions The device tree patches are based on Heiko's v4.8-armsoc/dts64. If requested, I could repost my series with the outstanding code patches or I could try folding those patches into mine. Since those patches aren't in 4.7-rc1 presumably they would also make sense to take through the MMC tree if others agree.
