2016-02-10phy: twl4030-usb: Fix unbalanced pm_runtime_enable on module reloadTony Lindgren
If we reload phy-twl4030-usb, we get a warning about unbalanced pm_runtime_enable. Let's fix the issue and also fix idling of the device on unload before we attempt to shut it down. If we don't properly idle the PHY before shutting it down on removal, the twl4030 ends up consuming about 62mW of extra power compared to running idle with the module loaded.

2015-12-20phy: rockchip-usb: expose the phy-internal PLLsHeiko Stuebner
The USB phys on Rockchip SoCs contain their own internal PLLs to create the 480MHz needed. Additionally this PLL output is also fed back into the core clock-controller as possible source for clocks like the GPU or others. Until now this was modelled incorrectly with a "virtual" factor clock in the clock controller. The one big caveat is that if we turn off the usb phy via the siddq signal, all analog components get turned off, including the PLLs. It is therefore possible that a source clock gets disabled without the clock driver ever knowing, possibly making the system hang. Therefore register the phy-plls as real clocks that the clock driver can then reference again normally, making the clock hirarchy finally reflect the actual hardware. The phy-ops get converted to simply turning that new clock on and off which in turn controls the siddq signal of the phy. Through this the driver gains handling for platform-specific data, to handle the phy->clock name association.

2015-12-16usb: musb: core: Fix handling of the phy notificationsTony Lindgren
We currently can't unload omap2430 MUSB platform glue driver module and this cause issues for fixing the MUSB code further. The reason we can't remove omap2430 is because it uses the PHY functions and also exports the omap_musb_mailbox function that some PHY drivers are using. Let's fix the issue by exporting a more generic musb_mailbox function from the MUSB core and allow platform glue layers to register phy_callback function as needed. And now we can now also get rid of the include/linux/musb-omap.h.
