* phy: rockchip-emmc: should be a child device of the GRFHeiko Stuebner2016-04-131-1/+4
| | | | | | | | | | | | | | | The emmc-phy is fully enclosed in the general register files (GRF). Therefore as seen from the device-tree it shouldn't be a separate platform- device but instead a sub-device of the GRF - using the simply-mfd mechanism. The driver entered the kernel in the current merge-window, so we can still adapt the binding without needing a fallback, as the binding hasn't been released with a full kernel yet.

| * phy: rockchip-usb: add handler for usb-uart functionalityHeiko Stuebner2016-03-011-36/+197
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most newer Rockchip SoCs provide the possibility to use a usb-phy as passthrough for the debug uart (uart2), making it possible to for example get console output without needing to open the device. This patch adds an early_initcall to enable this functionality conditionally via the commandline and also disables the corresponding usb controller in the devicetree. Currently only data for the rk3288 is provided, but at least the rk3188 and arm64 rk3368 also provide this functionality and will be enabled later. On a spliced usb cable the signals are tx on white wire(D+) and rx on green wire(D-). The one caveat is that currently the reconfiguration of the phy happens as early_initcall, as the code depends on the unflattened devicetree being available. Everything is fine if only a regular console is active as the console-replay will happen after the reconfiguation. But with earlycon active output up to smp-init currently will get lost. The phy is an optional property for the connected dwc2 controller, so we still provide the phy device but fail all phy-ops with -EBUSY to make sure the dwc2 does not try to transmit anything on the repurposed phy.

Let's fix the issue and also fix idling of the device on unload before we attempt to shut it down.

| * phy: rockchip-usb: expose the phy-internal PLLsHeiko Stuebner2015-12-201-27/+161
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Yoshihiro Shimoda gives us support for a new USB3 peripheral controller from Renesas. Other than these, the usual misc fixes all over the place.
| * usb: musb: core: Fix handling of the phy notificationsTony Lindgren2015-12-161-16/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
