Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

usb: Move definition of USB_EHCI_BIG_ENDIAN_MMIO et al. out side of the ifs. When CONFIG_USB_SUPPORT is not selected we get things like: scripts/kconfig/mconf Kconfig warning: (MIPS_SEAD3 && PMC_MSP && CPU_CAVIUM_OCTEON) selects USB_EHCI_BIG_ENDIAN_MMIO which has unmet direct dependencies (USB_SUPPORT && USB) It is much cleaner to make the various system Kconfigs select USB_EHCI_BIG_ENDIAN_MMIO rather than move the system config information into USB's Kconfig, but the warnings are annoying. Eliminate the warning by moving the definition of USB_EHCI_BIG_ENDIAN_MMIO outside of all the Kconfig if statements. While we are at it move USB_OHCI_BIG_ENDIAN_DESC, USB_OHCI_BIG_ENDIAN_MMIO, USB_OHCI_LITTLE_ENDIAN and USB_EHCI_BIG_ENDIAN_DESC too, as they could very well suffer similar problems for other systems.

usb: Put USB Kconfig items back under USB. commit 53c6bc24fdc8db87109a5760579cbb060fa644cf (usb: Don't make USB_ARCH_HAS_{XHCI,OHCI,EHCI} depend on USB_SUPPORT.) Removed the dependency of the USB_ARCH_HAS_* symbols on USB_SUPPORT. However the resulting Kconfig somehow caused many of the USB configuration items to appear under the top level devices menu. To fix this we reunite the 'menuconfig USB_SUPPORT' with the 'if USB_SUPPORT', and the config items magically go back to their desired location.

usb: host: make USB_ARCH_HAS_?HCI obsolete The three options USB_ARCH_HAS_{EHCI,OHCI,XHCI} are all well beyond their recommended shelf life. They have caused numerous build failures over the years because they are never completely correct, and with the move to splitting out the platform specific back-ends out of the driver, there is no real need for them any more. Also, the use of making USB_ARCH_HAS_HCD depend on it is questionable since one can always enable dummy_hc these days. This patch enables them unconditionally for all platforms and architectures, which means it is now possible to build host controller drivers for machines that are known not to come with this hardware, but that is just how we treat most other drivers. In order to minimise the impact on existing architecture code and defconfig files, all the Kconfig are left present for now. All platforms that currently do 'select USB_ARCH_HAS_*' should subsequently be changed not to select that. All drivers depending on USB_ARCH_HAS_HCD should be changed to depend on USB_SUPPORT instead.

---help---
Universal Serial Bus (USB) is a specification for a serial bus
subsystem which offers higher speeds and more features than the
traditional PC serial port. The bus supplies power to peripherals
and allows for hot swapping. Up to 127 USB peripherals can be
connected to a single USB host in a tree structure.
The USB host is the root of the tree, the peripherals are the
leaves and the inner nodes are special USB devices called hubs.
Most PCs now have USB host ports, used to connect peripherals
such as scanners, keyboards, mice, modems, cameras, disks,
flash memory, network links, and printers to the PC.
Say Y here if your computer has a host-side USB port and you want
to use USB devices. You then need to say Y to at least one of the
Host Controller Driver (HCD) options below. Choose a USB 1.1
controller, such as "UHCI HCD support" or "OHCI HCD support",
and "EHCI HCD (USB 2.0) support" except for older systems that
do not have USB 2.0 support. It doesn't normally hurt to select
them all if you are not certain.
If your system has a device-side USB port, used in the peripheral
side of the USB protocol, see the "USB Gadget" framework instead.
After choosing your HCD, then select drivers for the USB peripherals
you'll be using. You may want to check out the information provided
in <file:Documentation/usb/> and especially the links given in
<file:Documentation/usb/usb-help.txt>.
To compile this driver as a module, choose M here: the
module will be called usbcore.

usb: Introduce DesignWare USB3 DRD Driver The DesignWare USB3 is a highly configurable IP Core which can be instantiated as Dual-Role Device (DRD), Peripheral Only and Host Only (XHCI) configurations. Several other parameters can be configured like amount of FIFO space, amount of TX and RX endpoints, amount of Host Interrupters, etc. The current driver has been validated with a virtual model of version 1.73a of that core and with an FPGA burned with version 1.83a of the DRD core. We have support for PCIe bus, which is used on FPGA prototyping, and for the OMAP5, more adaptation (or glue) layers can be easily added and the driver is half prepared to handle any possible configuration the HW engineer has chosen considering we have the information on one of the GHWPARAMS registers to do runtime checking of certain features. More runtime checks can, and should, be added in order to make this driver even more flexible with regards to number of endpoints, FIFO sizes, transfer types, etc. While this supports only the device side, for now, we will add support for Host side (xHCI - see the updated series Sebastian has sent [1]) and OTG after we have it all stabilized.

---help---
This driver is for USB parallel port adapters that use the Lucent
Technologies USS-720 chip. These cables are plugged into your USB
port and provide USB compatibility to peripherals designed with
parallel port interfaces.
The chip has two modes: automatic mode and manual mode. In automatic
mode, it looks to the computer like a standard USB printer. Only
printers may be connected to the USS-720 in this mode. The generic
USB printer driver ("USB Printer support", above) may be used in
that mode, and you can say N here if you want to use the chip only
in this mode.
Manual mode is not limited to printers, any parallel port
device should work. This driver utilizes manual mode.
Note however that some operations are three orders of magnitude
slower than on a PCI/ISA Parallel Port, so timing critical
applications might not work.
Say Y here if you own an USS-720 USB->Parport cable and intend to
connect anything other than a printer to it.
To compile this driver as a module, choose M here: the
module will be called uss720.

usb: Kconfig: using select for USB_COMMON dependency According to (badf6d47f8a9 "usb: common: rework CONFIG_USB_COMMON logic") we should select USB_COMMON at Kconfig when usb common stuffs are needed, but some of Kconfig enties have not followed it, update them.

UTMI+ Low Pin Interface (ULPI) is specification for a commonly used
USB 2.0 PHY interface. The ULPI specification defines a standard set
of registers that can be used to detect the vendor and product which
allows ULPI to be handled as a bus. This module is the driver for that
bus.
The ULPI interfaces (the buses) are registered by the drivers for USB
controllers which support ULPI register access and have ULPI PHY
attached to them. The ULPI PHY drivers themselves are normal PHY
drivers.
ULPI PHYs provide often functions such as ADP sensing/probing (OTG
protocol) and USB charger detection.
To compile this driver as a module, choose M here: the module will
be called ulpi.
USB: Use menuconfig objects Make a "menuconfig" out of the Kconfig objects "menu, ..., endmenu", so that the user can disable all the options in that menu at once instead of having to disable each option separately.
