Hello Ulf and Adrian, Sorry for delay the new version for this topic. Actually I have no platform available to test phy stuff since v4. Now, I can rework it.:) I remove rpm support from v5 because this patchset just need to focus on phy stuff, which will make the changes more precise. Another reason is that phy_power_on take too much time from rpm, however the power profit gained from phy_power_off is little due to the low power mechanism with the phy itself observed from experiments.
v4 can be found here: https://patchwork.kernel.org/patch/7463251/ Note: Phy is mandatory requirement for arasan,sdhci-5.1, so we introduce generic phy support for sdhci-of-arasan.
