common: usb: fix checking condition

2016-01-16T06:06:55+00:00

We support max USB_MAXENDPOINTS, so need to use
"epno >= USB_MAXENDPOINTS", but not "epno > USB_MAXENDPOINTS".
If use ">", we may exceeds the array of if_desc->ep_desc.

usb: Move determination of TT hub address/port into separate function

2015-12-31T15:16:29+00:00

Start split and complete split tokens need the hub address and the
downstream port of the first HS hub (device view).

The core of the function was duplicated in both host/ehci_hcd and
musb-new/usb-compat.h.

usb: Alloc buffer for USB descriptor dynamically

2015-12-31T09:05:31+00:00

The configuration descriptor includes all interface, endpoint and
auxiliary descriptors (e.g. report, union) so 512 bytes may not be enough.

Move ALLOC_CACHE_ALIGN_BUFFER() to the new memalign.h header

2015-09-11T21:15:20+00:00

Now that we have a new header file for cache-aligned allocation, we should
move the stack-based allocation macro there also.

usb: Add an usb_device parameter to usb_reset_root_port

2015-07-21T23:39:35+00:00

Add an usb_device parameter to usb_reset_root_port so that it knows which
root-port it is resetting. This is necessary for proper device-model support
for usb_reset_root_port.

Also remove a duplicate declaration of usb_reset_root_port() from usb.h .

usb: Pass device instead of portnr to usb_legacy_port_reset

2015-07-21T23:39:35+00:00

Pass the usb_device instead of the portnr to usb_legacy_port_reset and
rename it to usb_hub_port_reset as there is nothing legacy about it.

usb: usb_setup_device: Drop unneeded portnr function argument

Drop the unneeded portnr function argument, the portnr is part of the
usb_device struct which is passed via the dev argument.

usb: Drop device-model specific copy of usb_legacy_port_reset

2015-07-21T23:39:34+00:00

The device-model usb_legacy_port_reset function calls the device-model
usb_port_reset function which is a 1 on 1 copy of the non dm
usb_legacy_port_reset and this is the only use of usb_port_reset in all
of u-boot.

Drop both, and alway use the usb_legacy_port_reset() version in
common/usb.c .

Also while at it make it static as it is only used in common/usb.c .

The compiler did not catch this as it was marked __maybe_unused.

usb: add device connection/disconnection detection

2015-05-15T00:49:33+00:00

Provide a function to detect USB device insertion/removal in order to
avoid having to do USB enumeration in a tight loop when trying to detect
peripheral hotplugging.
