Hi Community, Felipe,
I am trying to get UAC1 working on Freescale i.MX6SL EVK board (as USB
peripheral device), which is based on kernel 3.10.17.
In order to get UAC1 working with my Ubuntu 12.04 LTS host, I have to
make a few changes to driver/usb/gadget/f_uac1.c
I check Mr. Torvald's mas
When __usb_find_phy_dev() does not return error and
try_module_get() fails, return -ENODEV

The variable $(PWD) is useless, and it may break the compilation.
For example, it breaks the kernel compilation when it's done with
buildroot :
/home/trem/Codes/armadeus/armadeus/buildroot/output/host/usr/bin/ccache
/home/trem/Codes/armadeus/armadeus/buildroot/output/host/usr/bin/arm-buildroot-l

Changes two simple if statements to switch statements.
Fixes some issues reported by checkpatch.pl like whitespace.
Bracing changes so all arms of a statement have consistent bracing.

We introduce the connect API at usb_gadget_driver, the udc driver
uses it to tell gadget driver that it is ready to CONNECT, and the
dp can be pulled up from now on.
Meanwhile, we introduce an API usb_udc_ready_to_connect to encapsulate
above operation.

Except for chipidea driver, all other udc drivers will tell the
gadget driver that they are ready to pullup dp at udc_start, it
is the default behaviour.
The chipidea driver is ready to pullup dp when the vbus is there,
and isn't ready to pullup dp when the vbus is not there. Other
udc drivers whi
We have a discussion at http://www.spinics.net/lists/linux-usb/msg111860.html
about current pullup dp limitations, this patchset is intended to fix two
problems in discussion, they are:
- Some function drivers (uvc, obex) can't pullup on demand, they needs to
pullup dp after app loads.
- Some udc d
It is used for udc to pullup dp when necessary

Each function driver should activate itself at its function driver
when necessary. Most of functions would like to activate them just
after binding, but some may have special requirements for when to
activate themselves, eg, uvc, it needs the app to open video device
first.
We do not need to consi
For these functions, it has no special requirement when to activate them,
so activate their function at function.bind.

- If the udc is ready to pullup dp and all functions at gadget driver
want to pullup dp, it will pullup dp.
- If the udc doesn't want to pullup dp or one of functions at gadget
driver doesn't want to pullup up. it will pull down dp.
