05f0b20b67 usb: gadget: Export recommended BESL values
Currently there's no option for the controller driver to report the
recommended Best Effort Service Latency (BESL) when operating with LPM
support. Add new fields in usb_dcd_config_params to export the
recommended baseline and deep BESL values for the function drivers to
set the proper BESL value in the BOS descriptor.

d1dec5ca5f ARM: s3c64xx: squash samsung_usb_phy.h into setup-usb-phy.c
This is only used by arch/arm/mach-s3c64xx/setup-usb-phy.c

$ git grep samsung_usb_phy_type
include/linux/usb/samsung_usb_phy.h:enum samsung_usb_phy_type {
$ git grep USB_PHY_TYPE_DEVICE
arch/arm/mach-s3c64xx/setup-usb-phy.c:  if (type == USB_PHY_TYPE_DEVICE)
arch/arm/mach-s3c64xx/setup-usb-phy.c:  if (type == USB_PHY_TYPE_DEVICE)
include/linux/usb/samsung_usb_phy.h:    USB_PHY_TYPE_DEVICE,
$ git grep USB_PHY_TYPE_HOST
include/linux/usb/samsung_usb_phy.h:    USB_PHY_TYPE_HOST,

Actually, 'enum samsung_usb_phy_type' is unused; the 'type' parameter
has 'int' type. Anyway, there is no need to declare this enum in the
globally visible header. Squash the header.

7b81cb6bdd usb: add a HCD_DMA flag instead of guestimating DMA capabilities
The usb core is the only major place in the kernel that checks for
a non-NULL device dma_mask to see if a device is DMA capable.  This
is generally a bad idea, as all major busses always set up a DMA mask,
even if the device is not DMA capable - in fact bus layers like PCI
can't even know if a device is DMA capable at enumeration time.  This
leads to lots of workaround in HCD drivers, and also prevented us from
setting up a DMA mask for platform devices by default last time we
tried.

Replace this guess with an explicit HCD_DMA that is set by drivers that
appear to have DMA support.

edfbcb321f usb: add a hcd_uses_dma helper
The USB buffer allocation code is the only place in the usb core (and in
fact the whole kernel) that uses is_device_dma_capable, while the URB
mapping code uses the uses_dma flag in struct usb_bus.  Switch the buffer
allocation to use the uses_dma flag used by the rest of the USB code,
and create a helper in hcd.h that checks this flag as well as the
CONFIG_HAS_DMA to simplify the caller a bit.

71ed79b0e4 USB: Move wusbcore and UWB to staging as it is obsolete
The UWB and wusbcore code is long obsolete, so let us just move the code
out of the real part of the kernel and into the drivers/staging/
location with plans to remove it entirely in a few releases.

(armadillo800eva) was removed by the commit 1fa59bda21 ("ARM: shmobile:
Remove legacy board code for Armadillo-800 EVA"). So, this patch

b0310c2f09 USB: use genalloc for USB HCs with local memory
For HCs that have local memory, replace the current DMA API usage with
a genalloc generic allocator to manage the mappings for these devices.
To help users, introduce a new HCD API, usb_hcd_setup_local_mem() that
will setup up the genalloc backing up the device local memory. It will
be used in subsequent patches.  This is in preparation for dropping
the existing "coherent" dma mem declaration APIs.  The current
implementation was relying on a short circuit in the DMA API that in
the end, was acting as an allocator for these type of devices.

3370db3519 usb: typec: Registering real device entries for the muxes
Registering real device entries (struct device) for the mode
muxes as well as for the orientation switches.

The Type-C mux code was deliberately attempting to avoid
creation of separate device entries for the orientation
switch and the mode switch (alternate modes) because they
are not physical devices. They are functions of a single
physical multiplexer/demultiplexer switch device.

Unfortunately because of the dependency we still have on the
underlying mux device driver, we had to put in hacks like
the one in the commit 3e3b81965c ("usb: typec: mux: Take
care of driver module reference counting") to make sure the
driver does not disappear from underneath us. Even with
those hacks we were still left with a potential NUll pointer
dereference scenario, so just creating the device entries,
and letting the core take care of the dependencies. No more
hacks needed.

7893f9e1c2 usb: typec: tcpm: Notify the tcpc to start connection-detection for SRPs
Some tcpc device-drivers need to explicitly be told to watch for connection
events, otherwise the tcpc will not generate any TCPM_CC_EVENTs and devices
being plugged into the Type-C port will not be noticed.

For dual-role ports tcpm_start_drp_toggling() is used to tell the tcpc to
watch for connection events. Sofar we lack a similar callback to the tcpc
for single-role ports. With some tcpc-s such as the fusb302 this means
no TCPM_CC_EVENTs will be generated when the port is configured as a
single-role port.

This commit renames start_drp_toggling to start_toggling and since the
device-properties are parsed by the tcpm-core, adds a port_type parameter
to the start_toggling callback so that the tcpc_dev driver knows the
port-type and can act accordingly when it starts toggling.

The new start_toggling callback now always gets called if defined, instead
of only being called for DRP ports.

To avoid this causing undesirable functional changes all existing
start_drp_toggling implementations are not only renamed to start_toggling,
but also get a port_type check added and return -EOPNOTSUPP when port_type
is not DRP.

540bfab7fb usb: typec: Rationalize the API for the muxes
Since with accessory modes there is no need for additional
identification when requesting a handle to the mux, we can
replace the second parameter that is passed to the
typec_mux_get() function with a pointer to alternate mode
description structure, and simply passing NULL with
accessory modes.

This change means the naming of the mux device connections
can be updated. Alternate and Accessory Modes will both be
handled with muxes named "mode-switch", and the orientation
switches will be named "orientation-switch".

Future identification of the alternate modes will be later
done using device property "svid" of the mux.

5ac93d0c5d USB changes for v4.21
So it looks like folks are interested in dwc3 again. Almost 64% of the
 changes are in dwc3 this time around with some other bits in gadget
 functions and dwc2.
 
 There are two important parts here: a. removal of the waitqueue from
 dwc3's dequeue implementation, which will guarantee that gadget
 functions can dequeue from any context and; b. better method for
 starting isochronous transfers to avoid, as much as possible, missed
 isoc frames.
 
 Apart from these, we have the usual set of non-critical fixes and new
 features all over the place.

781f0766cc USB: Wait for extra delay time after USB_PORT_FEAT_RESET for quirky hub
Devices connected under Terminus Technology Inc. Hub (1a40:0101) may

[  206.063325] usb 3-2.4: reset full-speed USB device number 4 using xhci_hcd

I:  If#= 0 Alt= 0 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=00 Driver=hub

Some expirements indicate that the USB devices connected to the hub are
innocent, it's the hub itself is to blame. The hub needs extra delay
time after it resets its port.

Hence wait for extra delay, if the device is connected to this quirky
hub.

23b5f73266 usb: typec: tcpm: Do not disconnect link for self powered devices
During HARD_RESET the data link is disconnected.
For self powered device, the spec is advising against doing that.

>From USB_PD_R3_0
7.1.5 Response to Hard Resets
Device operation during and after a Hard Reset is defined as follows:
Self-powered devices Should Not disconnect from USB during a Hard Reset
(see Section 9.1.2).
Bus powered devices will disconnect from USB during a Hard Reset due to the
loss of their power source.

Tackle this by letting TCPM know whether the device is self or bus powered.

This overcomes unnecessary port disconnections from hard reset.
Also, speeds up the enumeration time when connected to Type-A ports.

The Power Domains are optional for UAC3 configuration but all
UAC3 devices shall include at least one BADD configuration where
the support for Power Domains is compulsory.

This patch adds a set of features/helpers to parse these power
domains and change their status.

0f292f023f ALSA: usb-audio: Add support for Processing Units in UAC3
This patch adds support for the Processig Units defined in
the UAC3 spec. The main difference with the previous specs
is the lack of on/off switches in the controls for these
units and the addiction of the new Multi Function Processing
Unit.

The current version of the UAC3 spec doesn't define any
useful controls for the new Multi Function Processing Unit
so no control will get created once this unit is parsed.

379cacc5e5 USB: Report wakeup events on root-hub ports
When a USB device attached to a root-hub port sends a wakeup request
to a sleeping system, we do not report the wakeup event to the PM
core.  This is because a system resume involves waking up all
suspended USB ports as quickly as possible; without the normal
USB_RESUME_TIMEOUT delay, the host controller driver doesn't set the
USB_PORT_STAT_C_SUSPEND flag and so usb_port_resume() doesn't realize
that a wakeup request was received.

However, some environments (such as Chrome OS) want to have all wakeup
events reported so they can be ascribed to the appropriate device.  To
accommodate these environments, this patch adds a new routine to the
hub driver and a corresponding new HCD method to be used when a root
hub resumes.  The HCD method returns a bitmap of ports that have
initiated a wakeup signal but not yet completed resuming.  The hub
driver can then report to the PM core that the child devices attached
to these ports initiated a wakeup event.

1d38f5d828 ALSA: usb-audio: UAC3 Add support for connector insertion.
This adds support for the UAC3 insertion controls. The status
is reported as a boolean value in the same way it used to do
for UAC2. Hence, the presence of any connector in the response
will make the control saying the jack is connected.

The UAC2 support for this control has been moved to a dedicated
control for connectors as both UAC2 and UAC3 follow a specific
Control Request Parameter Block for this control. This parameter
block for UAC3 could not be read in the same simplistic
manner as in UAC2.

This implementation is not requesting additional information
from the HIGH CAPABILITY Connectors descriptor.

Tested with an UAC3 device with UAC2 as legacy configuration.
The connector status can be read with `amixer` and the interrupt
is also caught with `alsactl monitor`.

e02d37bf55 sound updates for 4.17-rc1
This became a large update.  The changes are scattered widely,
 and majority of them are attributed to ASoC componentization.
 The gitk output made me dizzy, but it's slightly better than
 London tube.
 
 OK, below are some highlights:
 
 - Continued hardening works in ALSA PCM core; most of the
   existing syzkaller reports should have been covered.
 
 - USB-audio got the initial USB Audio Class 3 support, as well
   as UAC2 jack detection support and more DSD-device support.
 
 - ASoC componentization: finally each individual driver was
   converted to components framework, which is more future-proof
   for further works.  Most of conversations were systematic.
 
 - Lots of fixes for Intel Baytrail / Cherrytrail devices with
   Realtek codecs, typically tablets and small PCs.
 
 - Fixes / cleanups for Samsung Odroid systems
 
 - Cleanups in Freescale SSI driver
 
 - New ASoC drivers:
   * AKM AK4458 and AK5558 codecs
   * A few AMD based machine drivers
   * Intel Kabylake machine drivers
   * Maxim MAX9759 codec
   * Motorola CPCAP codec
   * Socionext Uniphier SoCs
   * TI PCM1789 and TDA7419 codecs
 
 - Retirement of Blackfin drivers along with architecture removal.

f5a8eb632b arch: remove obsolete architecture ports
This removes the entire architecture code for blackfin, cris, frv, m32r,
 metag, mn10300, score, and tile, including the associated device drivers.
 
 I have been working with the (former) maintainers for each one to ensure
 that my interpretation was right and the code is definitely unused in
 mainline kernels. Many had fond memories of working on the respective
 ports to start with and getting them included in upstream, but also saw
 no point in keeping the port alive without any users.
 
 In the end, it seems that while the eight architectures are extremely
 different, they all suffered the same fate: There was one company
 in charge of an SoC line, a CPU microarchitecture and a software
 ecosystem, which was more costly than licensing newer off-the-shelf
 CPU cores from a third party (typically ARM, MIPS, or RISC-V). It seems
 that all the SoC product lines are still around, but have not used the
 custom CPU architectures for several years at this point. In contrast,
 CPU instruction sets that remain popular and have actively maintained
 kernel ports tend to all be used across multiple licensees.
 
 The removal came out of a discussion that is now documented at
 https://lwn.net/Articles/748074/. Unlike the original plans, I'm not
 marking any ports as deprecated but remove them all at once after I made
 sure that they are all unused. Some architectures (notably tile, mn10300,
 and blackfin) are still being shipped in products with old kernels,
 but those products will never be updated to newer kernel releases.
 
 After this series, we still have a few architectures without mainline
 gcc support:
 
 - unicore32 and hexagon both have very outdated gcc releases, but the
   maintainers promised to work on providing something newer. At least
   in case of hexagon, this will only be llvm, not gcc.
 
 - openrisc, risc-v and nds32 are still in the process of finishing their
   support or getting it added to mainline gcc in the first place.
   They all have patched gcc-7.3 ports that work to some degree, but
   complete upstream support won't happen before gcc-8.1. Csky posted
   their first kernel patch set last week, their situation will be similar.

 which is intended to support further core work.  The goal is to make it
 easier to do further core work by removing the need to special case all

 quite a few for simple devices but also some more advanced ones with
 more substantial code.
 
  - The biggest thing is the huge series from Morimoto-san which
    converted everything over to components.  This is a huge change by
    code volume but was fairly mechanical
  - Many fixes for some of the Realtek based Baytrail systems covering
    both the CODECs and the CPUs, contributed by Hans de Goode.
  - Lots of cleanups for Samsung based Odroid systems from Sylwester

  - The Blackfin drivers have been removed as part of the removal of the
