[ Upstream commit 23b5f73266e59a598c1e5dd435d87651b5a7626b ] 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.

commit 781f0766cc41a9dd2e5d118ef4b1d5d89430257b upstream. Devices connected under Terminus Technology Inc.

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.

Here is the big USB and phy driver patch set for 4.19-rc1.
Nothing huge but there was a lot of work that happened this development
cycle:
- lots of type-c work, with drivers graduating out of staging,
and displayport support being added.
- new PHY drivers
- the normal collection of gadget driver updates and fixes
- code churn to work on the urb handling path, using irqsave()
everywhere in anticipation of making this codepath a lot
simpler in the future.
- usbserial driver fixes and reworks
- other misc changes
Full details are in the shortlog.
All of these have been in linux-next with no reported issues for a
while.

Thee USB Audio Class 3 (UAC3) introduces Power Domains as a new feature to let a host turn individual parts of an audio function to different power states via USB requests. This lets the device get to know a bit amore about what the host is up to in order to optimize power consumption efficiently. 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.

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.

In order for the muxes to be usable with alternate modes, the alternate mode devices will need also to be able to get a handle to the muxes on top of the port devices. To make that possible, the muxes need to be possible to request with an identifier. This will change the API so that the mux identifier is given as a function parameter to typec_mux_get(), and the hard-coded "typec-mux" is replaced with that value.

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.

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`.

Move reset controls from ehci-tegra to tegra-phy in order to resolve the problem. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

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.

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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJawdL2AAoJEGCrR//JCVInuH0P/RJAZh1nTD+TR34ZhJq2TBoo PgygwDU7Z2+tQVU+EZ453Gywz9/NMRFk1RWAZqrLix4ZtyIMvC6A1qfT2yH1Y7Fb Qh6tccQeLe4ezq5u4S/46R/fQXu3Txr92yVwzJJUuPyU0arF9rv5MmI8e6p7L1en yb74kSEaCe+/eMlsEj1Cc1dgthDNXGKIURHkRsILoweysCpesjiTg4qDcL+yTibV FP2wjVbniKESMKS6qL71tiT5sexvLsLwMNcGiHPj94qCIQuI7DLhLdBVsL5Su6gI sbtgv0dsq4auRYAbQdMaH1hFvu6WptsuttIbOMnz2Yegi2z28H8uVXkbk2WVLbqG ZESUwutGh8MzOL2RJ4jyyQq5sfo++CRGlfKjr6ImZRv03dv0pe/W85062cK5cKNs cgDDJjGRorOXW7dyU6jG2gRqODOQBObIv3w5efdq5OgzOWlbI4EC+Y5u1Z0JF/76 pSwtGXA6YhwC+9LLAlnVTHG+yOwuLmAICgoKcTbzTVDKA2YQZG/cYuQfI5S1wD8e X6urPx3Md2GCwLXQ9mzKBzKZUpu/Tuhx0NvwF4qVxy6x1PELjn68zuP7abDHr46r 57/09ooVN+iXXnEGMtQVS/OPvYHSa2NgTSZz6Y86lCRbZmUOOlK31RDNlMvYNA+s 3iIVHovno/JuJnTOE8LY =fQ8z -----END PGP SIGNATURE----- Merge tag 'arch-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pul removal of obsolete architecture ports from Arnd Bergmann: "This removes the entire architecture code for blackfin, cris, frv, m32r, metag, mn10300, score, and tile, including the associated device drivers.

This is a *very* big release for ASoC. Not much change in the core but
there s the transition of all the individual drivers over to components
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
the different driver classes in the core, many of the devices end up
being used in multiple roles in modern systems.
We also have quite a lot of new drivers added this month of all kinds,
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
Nawrocki.
- The Freescale SSI driver also got a lot of cleanups from Nicolin
Chen.
- The Blackfin drivers have been removed as part of the removal of the
architecture.
- New drivers for AKM AK4458 and AK5558, several AMD based machines,
several Intel based machines, Maxim MAX9759, Motorola CPCAP,
Socionext Uniphier SoCs, and TI PCM1789 and TDA7419

Quite a lot happened in this cycle, with a total of 95 non-merge commits. The most interesting parts are listed below: Synopsys has been adding better support for USB 3.1 to dwc3. The same series also sets g_mass_storage's max speed to SSP. Roger Quadros (TI) added support for dual-role using the OTG block available in some dwc3 implementations, this makes sure that AM437x can swap roles in runtime.

This patch fixes code readability and should have no functional change. Correct uac control query functions to account for the 1-based indexing of USB Audio Class control identifiers. The function parameter, u8 control, should be the constant defined in audio-v2.h to identify the control to be checked for readability or writeability. This patch fixes all callers that had adjusted, and makes explicit the mapping between audio_feature_info[] array index and the associated control identifier.

Some UDC may want to allocate endpoints dynamically, either because the HW supports an arbitrary large number or because (like the Aspeed BMC SoCs), the pool of HW endpoints is shared between multiple gadgets. The allocation side can be done rather easily using the existing match_ep() UDC hook. However we have no good place to "free" them. This implements a "simple" variant of this, which calls an EP dispose callback on all EPs associated with a gadget when the composite device gets unbound. This is required by my upcoming Aspeed vHub driver. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>

Setting the mux to MUX_NONE and the switch to USB_SWITCH_DISCONNECT when the data-role is device is not correct. Plenty of devices support operating as USB device through a (separate) USB device controller. We really need 2 different versions of USB_SWITCH_CONNECT, USB_SWITCH_CONNECT_HOST and USB_SWITCH_DEVICE. Rather then modifying the tcpc_usb_switch enum for this, simply remove it and switch to the usb_role enum which provides exactly this, this will save use needing to convert betweent the 2 enums when calling an usb-role-switch driver later. Besides switching to the usb_role type, this commit also actually sets the mux to TYPEC_MUX_USB and the switch to USB_ROLE_DEVICE instead of setting both to none when the data-role is device. This commit also makes tcpm_reset_port() call tcpm_mux_set(port, TYPEC_MUX_NONE, USB_ROLE_NONE) so that the mux and switch do _not_ stay in their last mode after a detach.

USB Type-C specification v1.2 separated the power and data roles more clearly. Dual-Role-Data term was introduced, and the meaning of DRP was changed from "Dual-Role-Port" to "Dual-Role-Power". In order to allow the port drivers to describe the capabilities of the ports more clearly according to the newest specifications, introducing separate definitions for the data roles.

USB role switch is a device that can be used to choose the data role for USB connector. With dual-role capable USB controllers, the controller itself will be the switch, but on some platforms the USB host and device controllers are separate IPs and there is a mux between them and the connector. On those platforms the mux driver will need to register the switch. With USB Type-C connectors, the host-to-device relationship is negotiated over the Configuration Channel (CC). That means the USB Type-C drivers need to be in control of the role switch. The class provides a simple API for the USB Type-C drivers for the control. For other types of USB connectors (mainly microAB) the class provides user space control via sysfs attribute file that can be used to request role swapping from the switch.

USB Type-C connectors consist of various muxes and switches that route the pins on the connector to the right locations. The USB Type-C drivers need to be able to control the muxes, as they are the ones that know things like the cable plug orientation, and the current mode that was negotiated with the partner. This introduces a small API for registering and controlling cable plug orientation switches, and separate small API for registering and controlling pin multiplexer/demultiplexer switches that are needed with Accessory/Alternate Modes.

Recently released USB Audio Class 3.0 specification introduces many significant changes comparing to previous versions, like - new Power Domains, support for LPM/L1 - new Cluster descriptor - changed layout of all class-specific descriptors - new High Capability descriptors - New class-specific String descriptors - new and removed units - additional sources for interrupts - removed Type II Audio Data Formats - ... and many other things (check spec) It also provides backward compatibility through multiple configurations, as well as requires mandatory support for BADD (Basic Audio Device Definition) on each ADC3.0 compliant device This patch adds initial support of UAC3 specification that is enough for Generic I/O Profile (BAOF, BAIF) device support from BADD document.
