Sorry I don't get it. Obviously the RPM backend here doesn't initialize the TLL and if it only manages the clocks, can't we safely assume that the pm_runtime_get_sync will get clocks to speed and the driver does the TLL init ? > moreover, the patch 'mfd: Add omap-usbhs runtime PM support' is > already reverted. Ok, though if the ultimate goal is to move on to RPM, this would be a step back. Btw, which tree could I find the revert in ?
