We calculate difference between two readings of a clock to see how much time has elapsed. Part of the time between rq_clock(rq) - dl_se->deadline can indeed be accounted for by reading a different clock (i.e., rq_clock_task()) if the task was running during the period. And that is how dl_se->runti

Hi all, Here's a second version of the probe order issue series. This time I've added the USB1 resets to the PHYs, thus replacing the really ugly parts with something slightly better. Old device trees will still probe successfully, but instead of this bugfix they'll get a dev_warn(). The reset co

tegra_usb_phy_close() is supposed to undo the effects of tegra_usb_phy_init(). It is also currently added as the USB PHY shutdown callback, which is wrong, since tegra_usb_phy_init() is only called during probing wheras the shutdown callback can get called multiple times. This then leads to warning

When Tegra was converted to use the standard reset bindings, the PHY was forgotten, probably because all the resetting of the USB blocks were done in the EHCI driver. What also went unnoticed is that resetting the 1st on-chip USB module also wipes some of the UTMI pad configuration registers that a
