USB: add quirk for devices with broken LPM

2016-01-23T04:55:42+00:00

commit ad87e03213b552a5c33d5e1e7a19a73768397010 upstream.

Some USB device / host controller combinations seem to have problems
with Link Power Management.  For example, Steinar found that his xHCI
controller wouldn't handle bandwidth calculations correctly for two
video cards simultaneously when LPM was enabled, even though the bus
had plenty of bandwidth available.

This patch introduces a new quirk flag for devices that should remain
disabled for LPM, and creates quirk entries for Steinar's devices.

USB: chipidea updates for v4.3-rc1

The main changes are adding several system interfaces for
tuning performance, and each vendors can adjust them according
to their design configurations.

Others are tiny improvements, like more well siTD supports,
USB_DEVICE_A_HNP_SUPPORT supports, etc.

usb: patches for v4.3 merge window

New support for Allwinne SoC on the MUSB driver has been added to the list of
glue layers. MUSB also got support for building all DMA engines in one binary;
this will be great for distros.

DWC3 now has no trace of dev_dbg()/dev_vdbg() usage. We will rely solely on
tracing to debug DWC3. There was also a fix for memory corruption with EP0 when
maxpacket size transfers are > 512 bytes.

Robert's EP capabilities flags is making EP selection a lot simpler. UDCs are
now required to set these flags up when adding endpoints to the framework.

Other than these, we have the usual set of miscelaneous cleanups and minor
fixes.
