USB 3.0 Hub Changes

2011-03-14T01:07:11+00:00

Update the USB core to deal with USB 3.0 hubs.  These hubs have a slightly
different hub descriptor than USB 2.0 hubs, with a fixed (rather than
variable length) size.  Change the USB core's hub descriptor to have a
union for the last fields that differ.  Change the host controller drivers
that access those last fields (DeviceRemovable and PortPowerCtrlMask) to
use the union.

Translate the new version of the hub port status field into the old
version that khubd understands.  (Note: we need to fix it to translate the
roothub's port status once we stop converting it to USB 2.0 hub status
internally.)

Add new code to handle link state change status.  Send out new control
messages that are needed for USB 3.0 hubs, like Set Hub Depth.

This patch is a modified version of the original patch submitted by John
Youn.  It's updated to reflect the removal of the "bitmap" #define, and
change the hub descriptor accesses of a couple new host controller
drivers.

USB: Remove bitmap #define from hcd.h

2011-03-14T01:07:07+00:00

Using a #define to redefine a common variable name is a bad thing,
especially when the #define is in a header.  include/linux/usb/hcd.h
redefined bitmap to DeviceRemovable to avoid typing a long field in the
hub descriptor.  This has unintended side effects for files like
drivers/usb/core/devio.c that include that file, since another header
included after hcd.h has different variables named bitmap.

Remove the bitmap #define and replace instances of it in the host
controller code.  Cleanup the spaces around function calls and square
brackets while we're at it.

USB: HCD: Add usb_hcd prefix to exported functions

2011-02-04T19:48:18+00:00

The convention is to prefix symbols exported from the USB HCD core with
"usb_hcd".  This change makes unmap_urb_setup_for_dma() and
unmap_urb_for_dma() consistent with that.

USB: imx21-hcd - fix off by one resource size calculation

USB: imx21-hcd accept arbitary transfer buffer alignement.

2010-10-22T17:22:03+00:00

The hardware can only do DMA to 4 byte aligned addresses.
When this requirement is not met use PIO or a bounce buffer.

PIO is used when the buffer is small enough to directly
use the hardware data memory (2*maxpacket).

A bounce buffer is used for larger transfers.

USB: imx21-hcd: Fix isochronous endpoint idle

2010-10-22T17:22:02+00:00

Release the hardware resources and reset the internal HCD state
associated with an isochronous endpoint when the last URB queued
for it completes.

Previously this was only done in then endpoint_disable() method
causing usbtest 15 and 16 to hang when run twice in succession
without a disconnect.

USB: imx21-hcd: refactor hardware data memory management

2010-10-22T17:22:02+00:00

We already have fields describing the hardware data memory
(dmem_size and dmem_offset) in the HCD private data,
use them rather than the rather obscure read from the
hardware descriptor.
