dm: usb: Drop the get_dev() function

2016-05-17T15:54:43+00:00

This function is implemented by the legacy block functions now. Drop it.

usb: Change power-on / scanning timeout handling

2016-03-20T17:00:45+00:00

This patch changes the USB port scanning procedure and timeout
handling in the following ways:

a)
The power-on delay in usb_hub_power_on() is now reduced to a value of
max(100ms, "hub->desc.bPwrOn2PwrGood * 2"). The code does not wait
using mdelay, instead usb_hub_power_on() will wait before querying
the device in the scanning loop later. The total timeout for this
hub, which is 1 second + "hub->desc.bPwrOn2PwrGood * 2" is calculated
and will be used in the following per-port scanning loop as the timeout
to detect active USB devices on this hub.

b)
Don't delay the minimum delay (for power to stabilize) in
usb_hub_power_on(). Instead skip querying these devices in the scannig
loop until the delay time is reached.

c)
The ports are now scanned in a quasi parallel way. The current code did
wait for each (unconnected) port to reach its timeout and only then
continue with the next port. This patch now changes this to scan all
ports of all USB hubs quasi simultaneously. For this, all ports are added
to a scanning list. This list is scanned until all ports are ready
by either a) reaching the connection timeout (calculated earlier), or
by b) detecting a USB device. This results in a faster USB scan time as
the recursive scanning of USB hubs connected to the hub that's currently
being scanned will start earlier.

One small functional change to the original code is, that ports with
overcurrent detection will now get rescanned multiple times
(PORT_OVERCURRENT_MAX_SCAN_COUNT).

Without this patch:
starting USB...
USB0:   USB EHCI 1.00
scanning bus 0 for devices... 9 USB Device(s) found

time: 20.163 seconds

With this patch:
starting USB...
USB0:   USB EHCI 1.00
scanning bus 0 for devices... 9 USB Device(s) found

time: 1.822 seconds

So ~18.3 seconds of USB scanning time reduction.

dm: Drop the block_dev_desc_t typedef

2016-03-14T21:34:50+00:00

Use 'struct' instead of a typdef. Also since 'struct block_dev_desc' is long
and causes 80-column violations, rename it to struct blk_desc.

usb: Allow up to 7 storage devices

2016-01-07T17:27:07+00:00

The current limit of 5 is not enough for the driver model USB tests. Really
we should not have a limit but the driver model code still uses the
usb_dev_desc[] array, which has a limit.

Increasing the limit by 2 should not bother anyone. Adjust it.

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.

sandbox: usb: Allow finding a USB emulator for a device

2015-11-20T03:27:51+00:00

Each USB device has an emulator. Currently this can only be found by
supplying the 'pipe' value, which contains the device number. Add a way
to find it directly from the emulated device.
