usb: Don't reset the USB hub a 2nd time

2016-03-20T17:00:45Z

Debugging has shown, that all USB hubs are being reset twice while USB scanning. This introduces additional delays and makes USB scanning even more slow. Testing has shown that this 2nd USB hub reset doesn't seem to be necessary. This patch now removes this 2nd USB hub reset. Resulting in faster USB scan time. Here the current numbers: Without this patch: => time usb start starting USB... USB0: USB EHCI 1.00 scanning bus 0 for devices... 9 USB Device(s) found time: 24.003 seconds With this patch: => time usb start starting USB... USB0: USB EHCI 1.00 scanning bus 0 for devices... 9 USB Device(s) found time: 20.392 seconds So ~3.6 seconds of USB scanning time reduction.

common: usb: fix checking condition

2016-01-16T06:06:55Z

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

2015-12-31T15:16:29Z

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. Signed-off-by: Stefan Brüns Reviewed-by: Marek Vasut Reviewed-by: Hans de Goede Tested-by: Hans de Goede

usb: Alloc buffer for USB descriptor dynamically

2015-12-31T09:05:31Z

The configuration descriptor includes all interface, endpoint and auxiliary descriptors (e.g. report, union) so 512 bytes may not be enough. Signed-off-by: Stefan Brüns Reviewed-by: Marek Vasut Reviewed-by: Simon Glass

Move ALLOC_CACHE_ALIGN_BUFFER() to the new memalign.h header

2015-09-11T21:15:20Z

Now that we have a new header file for cache-aligned allocation, we should move the stack-based allocation macro there also. Signed-off-by: Simon Glass

usb: Add an usb_device parameter to usb_reset_root_port

2015-07-21T23:39:35Z

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 . Signed-off-by: Hans de Goede Acked-by: Simon Glass

usb: Pass device instead of portnr to usb_legacy_port_reset

2015-07-21T23:39:35Z

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. Signed-off-by: Hans de Goede Acked-by: Simon Glass

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. Signed-off-by: Hans de Goede Acked-by: Simon Glass

usb: Drop device-model specific copy of usb_legacy_port_reset

2015-07-21T23:39:34Z

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 . Signed-off-by: Hans de Goede Acked-by: Simon Glass
