usb: Handle -ENODEV from usb_lowlevel_init()

2014-08-29T09:27:42+00:00

As we support both Host and Device mode operation, an OTG controller
can return -ENODEV on a port which it found to be in Device mode during
Host mode scan for devices. In case -ENODEV is returned, print that the
port is not available and continue instead of screaming a bloody error
message.

usb: add enum usb_init_type parameter to usb_lowlevel_init

2013-10-20T21:45:26+00:00

This parameter will later be used to verify OTG ports.

usb: rename board_usb_init_type to usb_init_type

2013-10-20T21:45:26+00:00

This will be used by usb_lowlevel_init so it will
no longer be used by only board specific functions.

Move definition of enum usb_init_type higher in file
so that it will be available for usb_low_level_init.

usb: new board-specific USB init interface

2013-10-20T21:42:40+00:00

This commit unifies board-specific USB initialization implementations
under one symbol (usb_board_init), declaration of which is available in
usb.h.

New API allows selective initialization of USB controllers whenever needed.

USB: xHCI: Add stack support for xHCI

2013-10-20T21:42:38+00:00

This adds stack layer for eXtensible Host Controller Interface
which facilitates use of USB 3.0 in host mode.

Adapting xHCI host controller driver in linux-kernel
by Sarah Sharp to needs in u-boot.

Initial porting from Linux kernel version 3.4, with following
top commit history of drivers/usb/host/xhci* :
cf84055 xHCI: Cleanup isoc transfer ring when TD length mismatch found

This adds the basic xHCI host controller driver with bare minimum
features:
- Control/Bulk transfer support has been added with required
  infrastructure for necessary xHC data structures.
- Stream protocol hasn't been supported yet.
- No support for quirky devices has been added.

usb: Use well-known descriptor sizes when parsing configuration

2013-08-26T19:56:34+00:00

The existing USB configuration parsing code relies on the descriptors'
own length values when reading through the configuration blob. Since the
size of those descriptors is always well-defined, we should rather use
the known sizes instead of trusting device-provided values to be
correct. Also adds some safety to potential out-of-order descriptors.

usb: Update device class in usb device's descriptor

2013-05-05T21:54:22+00:00

Fetch the device class into usb device's dwcriptors,
so that the host controller's driver can use this info
to differentiate between HUB and DEVICE.
