All patches have been verified to work on Intel's BayTrail,
CherryTrail, and Broxton P platforms.
Lu Baolu (7):
regulator: fixed: add support for ACPI interface
usb: mux: add generic code for dual role port mux
usb: mux: add driver
that users are able
to control the port role from user space.
Some other archs (e.g. Renesas R-Car gen2 SoCs) need an external mux to
swap usb roles as well. This code could also be leveraged for those archs.

void portmux_unregister(struct portmux_dev *pdev);
I will add below ones.
struct portmux_dev *portmux_lookup_by_name(char *name);
int portmux_switch(struct portmux_dev *pdev, enum port_role);
The normal usage mode is
1) the mux device is registered as soon as a mux is detected with
portmux_register();
2) In components like USB PHY or changer drivers, the mux could
be retrieved with portmux_lookup_by_name() and controlled via
portmux_switch().
Is this helpful?

This patch fixes some wild pointers produced by xhci_mem_cleanup.
These wild pointers will cause system crash if xhci_mem_cleanup()
is called twice.

xhci_mem_init() should use @flags, instead of hardcode, for DMA
memory allocation.

In some Intel platforms, a single usb port is shared between USB host
and device controller. The shared port is under control of GPIO pins.
This patch adds the support for USB GPIO controlled port mux.
