2013-12-08usb: Use dev_is_pci() to check whether it is pci deviceYijing Wang1-1/+1

2013-12-08usb: hcd: Initialize USB phy if neededValentine Barshak1-0/+18
This adds external USB phy support to USB HCD driver that allows to find and initialize external USB phy, bound to the HCD, when the HCD is added. The usb_add_hcd function returns -EPROBE_DEFER if the USB phy, bound to the HCD, is not ready. If no USB phy is bound, the HCD is initialized as usual.

2013-12-08usb: hcd: Remove USB phy if neededValentine Barshak1-1/+13
This adds remove_phy flag to the HCD structure. If the flag is set and if hcd->phy is valid, the phy is shutdown and released whenever usb_add_hcd fails or usb_hcd_remove is called. This can be used by the HCD drivers to auto-remove the external USB phy when it is no longer needed.

2013-12-07ACPI / bind: Rework struct acpi_bus_typeRafael J. Wysocki1-20/+20
Replace the .find_device function pointer in struct acpi_bus_type with a new one, .find_companion, that is supposed to point to a function returning struct acpi_device pointer (instead of an int) and takes one argument (instead of two). This way the role of this callback is more clear and the implementation of it can be more straightforward. Update all of the users of struct acpi_bus_type (PCI, PNP/ACPI and USB) to reflect the structure change. Signed-off-by: Rafael J.

2013-12-07ACPI: Clean up inclusions of ACPI header filesLv Zheng1-1/+0
Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h> inclusions and remove some inclusions of those files that aren't necessary. First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h> should not be included directly from any files that are built for CONFIG_ACPI unset, because that generally leads to build warnings about undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set, <linux/acpi.h> includes those files and for CONFIG_ACPI unset it provides stub ACPI symbols to be used in that case. Second, there are ordering dependencies between those files that always have to be met. Namely, it is required that <acpi/acpi_bus.h> be included prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the latter depends on are always there. And <acpi/acpi.h> which provides basic ACPICA type declarations should always be included prior to any other ACPI headers in CONFIG_ACPI builds. That also is taken care of including <linux/acpi.h> as appropriate.
