e1b5d2bed6 usb: chipidea: core: handle usb role switch in a common way
Currently, ci_usb_role_switch_set() may be called before system resume
stage when suspended. Worse yet, ci_hdrc device may stay at RPM_ACTIVE
state which will cause pm_runtime_get_sync() fail to resume the device.
In this case, role-switch may unable to complete transition process due
to not exit from lpm state or due to lack some means after system resume.

Same as ci_cable_notifier(), usb_role_switch could handle its events based
on ci_hdrc_cable mechanism.

32c6fefb29 usb: phy: generic: make vcc regulator optional
phy-generic uses the existance of the property "vcc-supply" to see if a
regulator is optional or not. Use devm_regulator_get_optional() instead
which exists for this purpose. Using devm_regulator_get_optional()
avoids "supply vcc not found, using dummy regulator" messages.

Pull missed media updates from Mauro Carvalho Chehab:
 "It seems I screwed-up my previous pull request: it ends up that only
  half of the media patches that were in linux-next got merged in -rc1.

  The script which creates the signed tags silently failed due to
  5.19->6.0 so it ended generating a tag with incomplete stuff.

  So here are the missing parts:

   - a DVB core security fix

   - lots of fixes and cleanups for atomisp staging driver

   - old drivers that are VB1 are being moved to staging to be
     deprecated

   - several driver updates - mostly for embedded systems, but there are
     also some things addressing issues with some PC webcams, in the UVC
     video driver"

b295d484b9 device property: Allow const parameter to dev_fwnode()
It's not fully correct to take a const parameter pointer to a struct
and return a non-const pointer to a member of that struct.

Instead, introduce a const version of the dev_fwnode() API which takes
and returns const pointers and use it where it's applicable.

With this, convert dev_fwnode() to be a macro wrapper on top of const
and non-const APIs that chooses one based on the type.

55f223b8b4 usb: dwc2: platform: Improve error reporting for problems during .remove()
Returning an error value in a platform driver's remove callback results in
a generic error message being emitted by the driver core, but otherwise it
doesn't make a difference. The device goes away anyhow.

For each case where ret is non-zero the driver already emits an error
message, so suppress the generic error message by returning zero
unconditionally. (Side note: The return value handling was unreliable
anyhow as the value returned by dwc2_exit_hibernation() was overwritten
anyhow if hsotg->in_ppd was non-zero.)

d182bf156c usb: gadget: uvc: default the ctrl request interface offsets
For the userspace it is needed to distinguish between requests for the
control or streaming interface. The userspace would have to parse the
configfs to know which interface index it has to compare the ctrl
requests against. Since the interface numbers are not fixed, e.g. for
composite gadgets, the interface offset depends on the setup.

The kernel has this information when handing over the ctrl request to
the userspace. This patch removes the offset from the interface numbers
and expose the default interface defines in the uapi g_uvc.h.

48ed32482c usb: gadget: aspeed: Fix probe regression
Since commit fc274c1e99 ("USB: gadget: Add a new bus for gadgets"),
the gadget devices are proper driver core devices, which caused each
device to request pinmux settings:

 aspeed_vhub 1e6a0000.usb-vhub: Initialized virtual hub in USB2 mode
 aspeed-g5-pinctrl 1e6e2080.pinctrl: pin A7 already requested by 1e6a0000.usb-vhub; cannot claim for gadget.0
 aspeed-g5-pinctrl 1e6e2080.pinctrl: pin-232 (gadget.0) status -22
 aspeed-g5-pinctrl 1e6e2080.pinctrl: could not request pin 232 (A7) from group USB2AD  on device aspeed-g5-pinctrl
 g_mass_storage gadget.0: Error applying setting, reverse things back

The vhub driver has already claimed the pins, so prevent the gadgets
from requesting them too by setting the magic of_node_reused flag. This
causes the driver core to skip the mux request.

The gadget driver may wait on the request completion when it sets the

go through if the dwc->delayed_status is set so that the request can
complete. When the delayed_status is set, the Setup packet is already
processed, and the next phase should be either Data or Status. It's
unlikely that the host would cancel the control transfer and send a new
Setup packet during End Transfer command. But if that's the case, we can
try again when ep0state returns to EP0_SETUP_PHASE.
