      usb: gadget: convert all users to the new udc infrastructure · 0f91349b
      由 Sebastian Andrzej Siewior 提交于 
      peripheral drivers are using usb_add_gadget()/usb_del_gadget() to
register/unregister to the udc-core.

The udc-core will take the first available gadget driver and attach
function driver which is calling usb_gadget_register_driver(). This is
the same behaviour we have right now.

Only dummy_hcd was tested, the others were compiled tested.

      usb: gadget: introduce UDC Class · 2ccea03a
      由 Felipe Balbi 提交于 
      this class will be used to abstract away several of the duplicated
operations scattered among the USB gadget controller drivers.

Later, we can add an atomic notifier to tell interested drivers about
what's happening with the controller. Notifications such as suspend,
resume, enumerated, etc. will be useful, at a minimum, for implementing
usb charger detection.

As part of the converting process usb_gadget_probe_driver() is no longer
part of each udc but pushed into the ->stap() callback. The same for his
couterpart.

The core is currently set explicit to 'n'. It will be changed to 'y' once
all users are converted since it provides functions which clash with
other drivers.

      sanitize <linux/prefetch.h> usage · 268bb0ce
      由 Linus Torvalds 提交于 
      Commit e66eed65 ("list: remove prefetching from regular list
iterators") removed the include of prefetch.h from list.h, which
uncovered several cases that had apparently relied on that rather
obscure header file dependency.

So this fixes things up a bit, using

   grep -L linux/prefetch.h $(git grep -l '[^a-z_]prefetchw*(' -- '*.[ch]')
   grep -L 'prefetchw*(' $(git grep -l 'linux/prefetch.h' -- '*.[ch]')

to guide us in finding files that either need <linux/prefetch.h>
inclusion, or have it despite not needing it.

There are more of them around (mostly network drivers), but this gets
many core ones.

      USB: OTG: msm: Implement charger detection · d860852e
      由 Pavankumar Kondeti 提交于 
      Implement good battery algorithm defined in the battery charging V1.2 spec
for detecting different charging ports.  USB hardware is put into low power
mode when connected to a dedicated charging port.  vbus_draw and set_power
methods are implemented for determining the allowed current from Host in
different states (un-configured/suspend/configured).

The charger block is implemented using vendor specific registers and the
PHY used in MSM8960(28nm PHY) different from older targets like MSM8x60
and MSM7x30(45nm PHY).  The PHY vendor and product id registers are not
implemented in the above chipsets.  Hence PHY type is passed via platform
data.

      fsl/usb: Unused endpoint failure for USB gadget · ea437f39
      由 Ramneek Mehresh 提交于 
      Though USB controller works without this most of the time, an issue was faced
where USB was configured as printer device and it was dropping first
packet(64 bytes) in full speed mode due to DATA PID mismatch.
The problem gets resolved once unused endpoints are configured as bulk.
As per P1020 RM (Table17-31, bits 19-18, bits 3-2) "When only one endpoint
(RX or TX, but not both) of an endpoint pair is used, the unused endpoint
should be configured as a bulk type endpoint." So according to the RM,
this patch is initializing TX and RX endpoints as bulk type
