usb: gadget: move USB_BUFSIZ into global composite.h · e13f17ff

由 Sebastian Andrzej Siewior 提交于 9月 10, 2012

This patch moves USB_BUFSIZ into global header file as
USB_COMP_EP0_BUFSIZ. There is currently only one user (f_sourcesink)
besides composite which need it. Ideally f_sourcesink would have its
own ep0 buffer. Lets keep it that way it was for now.

usb: gadget: move global vars from epautoconf into struct usb_gadget · e87bb711

由 Sebastian Andrzej Siewior 提交于 9月 06, 2012

epautoconf has two global variables which count the endpoint number of
last assigned endpoint.
This patch removes the global variable and keeps it as per (UDC) gadget.
While here, the ifdef is removed and now the in and outpoint are
enumerated unconditionally. The dwc3 for instance supports 32 endpoints
in total.

This patch removes the global variable composite in composite.c.
The private data which was saved there is now passed via an additional
argument to the bind() function in struct usb_gadget_driver.

staging: ccg: include all sourced files · e220ff75

由 Sebastian Andrzej Siewior 提交于 9月 06, 2012

This Android gadget includes a bunch of .c files. Fixing normal gadgets
is not the real problem but this gadget is not always fixable since the
problem here are fundumential / design.

*I* wanted to get this removed but other people want to keep it even
though there were reports that Android itself is not using it. Some
poeple think that it is better to have this instead of nothing and other
argue that they need sdb and mass storage gadget. The sdb function is
not provided by ccg so I don't see the point of this. I don't see any
logical reasoning behind it and I decided that it is time for retreat.

This patch brings all dependencies of ccg into staging so I can do
whatever I want in drivers/usb/gadget without breaking ccg.

usb: gadget: push all usb_composite_driver structs into __refdata · c2ec75c2

由 Sebastian Andrzej Siewior 提交于 9月 06, 2012

As it turns out, Sam's comment was better than I initially assumed. This
patch pushes as struct usb_composite_driver data structures into
__refdata section to avoid a section missmatch report from modpost
because the ->bind() can be marked __init. The only downside is that
modpost does not check between ->bind() and other member. However, it is
temporary.

usb: gadget: move bind callback into driver struct usb_composite_driver · fac3a43e

It was moved to be an argument in 07a18bd7 ("usb gadget: don't
save bind callback in struct usb_composite_driver"). The reason was to
avoid the section missmatch. The warning was shown because ->bind is
marked as __init becuase it is a one time init. The warning can be also
suppresed by whitelisting the variable i.e. rename it to lets say _probe.

usb: gadget: get rid of USB_GADGET_{DUAL,SUPER}SPEED · 85b8614d

由 Michal Nazarewicz 提交于 8月 24, 2012

This commit removes USB_GADGET_DUALSPEED and USB_GADGET_SUPERSPEED
Kconfig options.  Since now kernel allows many UDC drivers to be
compiled, those options may turn to no longer be valid.  For
instance, if someone decides to build UDC that supports super
speed and UDC that supports high speed only, the latter will be
"assumed" to support super speed since USB_GADGET_SUPERSPEED will
be selected by the former.

The test of whether CONFIG_USB_GADGET_*SPEED was defined was just
an optimisation which removed otherwise dead code (ie. if UDC is
not dual speed, there is no need to handle cases that can happen
if speed is high).  This commit removes those checks.
