The 7211b0 has added the STB XHCI Synopsys controller and it will be used instead of the RPi based DWC USB controller. The new Synopsys XHCI controller core is the same one that is used on the 7216, but because of the way the STB USB PHY is used on both the A0 and B0, some of the PHY control is different.

The 7216 has the new USB XHCI controller from Synopsys. While this new controller and the PHY are similar to the STB versions, the major differences are: - Many of the registers and fields in the CTRL block have been removed or changed. - A new set of Synopsys control registers, BCHP_USB_XHCI_GBL, were added. - MDIO functionality has been replaced with direct access registers in the BCHP_USB_XHCI_GBL block. - Power up PHY defaults that had to be changed by MDIO in previous chips will now power up with the correct defaults. A new init module was created for this new Synopsys USB controller. A new compatible string was added and the driver will dispatch into one of two init modules based on it. A "reg-names" field was added so the driver can more easily get optional registers. A DT bindings document was also added for this driver.

The driver is being restructured in preparation for adding support for the new Synopsys USB conroller on the 7216. Since all the bugs and work-arounds in previous STB chips are supposed to be fixed, most of the code in phy-brcm-usb-init.c is not needed. Instead of adding more complexity to the already complicated phy-brcm-usb-init.c module, the driver will be restructured to use a vector table to dispatch into different C modules for the different controllers. There was also some general cleanup done including some ipp setup code that was incorrect.

Add the ability to handle USB wake events from USB devices when in S2 mode. Typically there is some additional configuration needed to tell the USB device to generate the wake event when suspended but this varies with the different USB device classes. For example, on USB Ethernet dongles, ethtool should be used to enable the magic packet wake functionality in the dongle. NOTE: This requires that the "power/wakeup" sysfs entry for the USB device generating the wakeup be set to "enabled". This functionality requires a special hardware sideband path that will trigger the AON_PM_L2 interrupt needed to wake the system from S2 even though the USB host controllers are in IDDQ (low power state) and most USB related clocks are shut off. For the sideband signaling to work we need to leave the usbx_freerun clock running, but this clock consumes very little power by design. There's a bug in the XHCI wake hardware so only EHCI/OHCI wake is currently supported.

Currently the Phy driver will put the USB phys into the max power saving mode (IDDQ) when there is no corresponding XHCI, EHCI or OHCI client (through rmmod, unbind or if the driver is not builtin). This change will also put the Phys into IDDQ mode on suspend so that S2 will get the additional power savings.

When the EHCI controller received a 512 byte USB packet that had to be broken into 2 256 byte bursts across the SCB bus AND there was a following 512 byte USB packet, the second burst of data from the first packet was sometimes being lost. If the burst size was changed to 128 bytes via the EBR_SCB_SIZE field in the USB_CTRL_EBRIDGE register we'd see the 4th 128 byte burst of the first packet being lost. This problem became much worse if other threads were running that accessed memory, like a memcpy test. Setting the EBR_SCB_SIZE to 512, which prevents breaking the EHCI USB packet (max size of 512 bytes) into bursts, fixed the problem.

During review it came to light that exposing the pll clock outside is not the right approach and struct phy_configure_opts_mipi_dphy exists just for that reason to transfer parameters to the phy. So drop the exposed clock and rely on the phy configure options to bring in the correct rate. That way we can also just drop the open coded timing struct and default values function.

pipe_wait() may be simple, but since it relies on the pipe lock, it means that we have to do the wakeup while holding the lock. That's unfortunate, because the very first thing the waked entity will want to do is to get the pipe lock for itself. So get rid of the pipe_wait() usage by simply releasing the pipe lock, doing the wakeup (if required) and then using wait_event_interruptible() to wait on the right condition instead. wait_event_interruptible() handles races on its own by comparing the wakeup condition before and after adding itself to the wait queue, so you can use an optimistic unlocked condition for it.
