This patch-series enables runtime power management on xhci-plat, dwc3-core, dwc3-exynos as well as on Samsung's USB 2.0 type and USB 3.0 type PHYs.
Based on 'next' branch of Felipe Balbi's USB tree. Changes from v2: - Using separate functions for USB PHY runtime power management, instead of using macros. - Adding 'pm_runtime_set_suspended()' api call in dwc3 core layer before enabling runtime pm. (Ideally, we should be explicitly make device 'suspended' or 'active' before enabling runtime pm on it). - Checking return code for 'put_sync' and 'get_sync' of USB-PHYs when waking up or suspending them from dwc3 core's runtime_pm callbacks. - Removed buggy pm_runtime_put() calls from driver's (xhci, dwc3 and PHY) remove functions. - Adding a patch to enable runtime power management of Samsung's USB 2.0 PHY (usb: phy: samsung: Enable runtime power management on usb2phy) Changes from v1: - Adding required PHY APIs to handle runtime power management instead of directly twiddling with phy->dev. - Handling runtime power management of usb PHYs in dwc3 core driver instead of in any glue layer. - Splitting the patch: [PATCH 4/4] usb: phy: samsung: Enable runtime power management on samsung-usb into required number to bifurcate functionality.
