usb: add support for hardware handled SET ADDR/CONFIG

2012-12-07T12:37:26+00:00

Some USB controllers like the one of the Rockchip 27xx handle some
requests in pure hardware. This is especially a problem for two
of them:
- SET ADDR which is used by our core to track the DEFAULT/ADDRESS
  state and is required for the drivers to work properly
- SET CONFIG which is used by our core to initialise the drivers
  by calling init_connection()
In these cases we need a way to notify the core that such requests
happened.
We do this by exporting two functions which directly notify the
core about these requests and perform the necessary init steps
required without doing the actual USB transfers. Special care is
needed because these functions could be called from an interrupt
handler. For this reason we still use the usb_queue and introduce
new IDs so that they are processed in order and safely.

No functional change is intended, both in the usbstack and on
targets without such quirks.

New USB charging system, part 1 - API rework and user-visible setting update

2010-06-05T10:05:27+00:00

1) "Charge during USB connection" option is now tristate: off/on/force. Currently "force" behaves just like "on", but in future it will allow charging even when it was not possible to positively identify a charger.

2) The H300 code has been adjusted to use the new system but there should be no functional differences, it already had the USB charging option and its USB/charging support is hardware controlled.

3) The Gigabeat S code has been adjusted to use the new system: the player now has the USB charging option, which wasn't previously available. The player will only charge at full speed when allowed to do so by a working USB host, so USB AC adapters won't work very well; however, they didn't work before either, so this is not a change in functionality.

4) The iPod Nano 2G code has been adjusted to use the new system: it already had the USB charging option. Using a USB AC adapter won't charge at full speed any more (it did before) - the old implementation was equivalent to the not-yet-implemented "force" option in the new system.

No other target should be affected. Support for the "force" mode and support for at least some other iPod models will come in a future commit :)

Change control handling to start expecting host packets before sending data to the host. This makes the handling less timing sensitive on some controllers

Reorganise USB stack defines. Now config.h decides which class drivers get enabled instead of usb_core.h

2009-05-23T14:30:20+00:00

Also enable HID, and use that as the dummy class instead of charging-only for controllers that have working interrupt transfers.

Add working USB HID driver, by Tomer Shalev (part of his GSoC work).

2009-05-16T15:30:09+00:00

This needs support for usb interrupt transfers, so there are some changes in various USB drivers as well (only usb-drv-arc supports it at this point, others won't have working HID yet).

HID is disabled for now, as the apps/ part is not included yet.

Add preliminary HID driver. It doesn't do anything yet, but that should change soon (FS#10116 by Tomer Shalev)

git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20750 a1c6a512-1295-4272-9138-f99709370657

reorganise usb_core.c a bit, to make the code more readable and more maintainable (FS#10150 by Tomer Shalev))

Correct Björn's name in various file headers.

USB detection changes. c200/e200: Consider USB to be powered when charger is plugged but detect USB connection by bus reset. When received, disconnect and restart the driver fully enabled. imx31: Fix hack used to make initial connect succeeded-- set PHY type before initial reset. General: Move some target code out of usb-drv-arc.c and implement it in respective usb sources and CPU headers so things stay clean.
