ehci-hcd.c, musb_core, usb.h: Add USB_DMA_MINALIGN define for cache alignment

2012-07-18T12:43:29+00:00

The USB spec says that 32 bytes is the minimum required alignment.
However on some platforms we have a larger minimum requirement for cache
coherency.  In those cases, use that value rather than the USB spec
minimum.  We add a cpp check to  to define USB_DMA_MINALIGN and
make use of it in ehci-hcd.c and musb_core.h.  We cannot use MAX() here
as we are not allowed to have tests inside of align(...).

[marek.vasut]: introduce some crazy macro voodoo
Signed-off-by: Marek Vasut 
[ilya.yanok]: moved external buffer fixes to separate patch,
we use {ALLOC,DEFINE}_ALIGN_BUFFER macros with alignment of USB_DMA_MINALIGN
for qh_list, qh and qtd structures to make sure they are proper aligned
for both controller and cache operations.

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: 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:

USB: move keyboard polling into kbd driver

2012-03-03T15:56:29+00:00

This moves keyboard polling logic from USB HCD drivers into USB
keyboard driver.  Remove usb_event_poll() as keyboard polling was
the only user of this API.  With this patch USB keyboard works with
EHCI controllers again.  Tested on a tegra2 seaboard.

usb: increase non-bulk timeout for slow chipsets.

2011-08-08T20:34:57+00:00

If you take a look at 96820a35, you'll see the original timeout was
CONFIG_SYS_HZ.  Which is 1000.  After the mentioned change, non-bulk timeout
was changed to 100.  This causes timeout failures on the dreamplug platform
when trying to initialize the usb microsd reader.

Add USB host ethernet adapter support

2011-02-19T19:32:36+00:00

This adds support for using USB Ethernet dongles in host mode. This is just
the framework - drivers will come later. A new config option called
CONFIG_USB_HOST_ETHER can be defined in board config files to switch this
on.

The was originally written by NVIDIA and was cleaned up for release by the
Chromium authors.

Fix EHCI usb submit timeout and unify with OHCI

2011-02-19T19:32:34+00:00

Changed both to use a common timeout for URB submission, since they were using
different values and EHCI's was too short.

Also fixed EHCI to actually check if urb submission succeeded, rather than
silently continuing into the weeds.

USB: fix create_pipe()

2010-05-27T18:59:48+00:00

create_pipe() can give wrong result if an expression is passed as the 'endpoint'
argument -- due to missing parentheses.

Thanks to Martin Mueller for finding the bug and providing the patch.
