usb: use linux/usb/ch9.h instead of usbdescriptors.h

2012-11-19T23:16:06+00:00

Linux usb/ch9.h seems to have all the same information (and more)
as usbdescriptors.h so use the former instead of the later one.

As a consequense of this change USB_SPEED_* values don't correspond
directly to EHCI speed encoding anymore, I've added necessary
recoding in EHCI driver. Also there is no point to put speed into
pipe anymore so it's removed and a bunch of host drivers fixed to
look at usb_device->speed instead.

Old usbdescriptors.h included is not removed as it seems to be
used by old USB device code.

This makes usb.h and usbdevice.h incompatible. Fortunately the
only place that tries to include both are the old MUSB code and
it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute
on musb_regs structure but this attribute seems to be unneeded
(old MUSB code doesn't support any DMA at all).

usb: fallback safely when a configuration descriptor is too large

2012-10-22T06:25:07+00:00

When a USB configuration descriptor was larger than our USB buffer
(512 bytes), we were skipping the full descriptor reading but then we
were still parsing and using it, triggering memory corruptions.
Now in that case, it just skips this device enumeration and displays the
appropriate message to the user, so he can fix the buffer if he wants.

This bug was triggered by some UVC webcams which have very large
configuration descriptors (e.g. a couple of kB) describing all their
supported video encodings.

usb: lowlevel interface change to support multiple controllers

2012-10-15T18:54:00+00:00

Carry an index in the lowlevel usb functions to make specify the
respective usb controller.

Also pass through an controller struct from lowlevel_init to the
creation of the root usb device of this controller.

Return values of submit_{control,bulk}_msg() functions
should be checked to detect possible error.

usb: pass cache-aligned buffer to usb_get_descriptor()

2012-07-18T12:43:42+00:00

usb_get_descriptor passes it's buffer argument directly to
usb_control_msg() so it has to be properly aligned/padded.

USB: Align buffers at cacheline

2012-05-20T06:32:32+00:00

This avoids cache-alignment warnings shown in console
when a usb command is entered.

Whenever X bytes of unaligned buffer is invalidated, arm core
invalidates X + Y bytes as per the cache line size and throws
these warnings.

usb: use noinline define

2012-05-20T06:32:31+00:00

Building usb for Blackfin boards fails as we get linux/compiler.h
included which expands the "noinline" inside of the attribute and
we get attribute(attribute(noinline)).

Explicitly use the helper define to avoid this.

usb: replace wait_ms() with mdelay()

2012-03-18T23:08:16+00:00

Common code has a mdelay() func, so use that instead of the usb-specific
wait_ms() func.  This also fixes the build errors:
