Exynos5422 DWC3 module support two clk USBD300 and SCLK_USBD300
so add missing code to enable/disable code and suspend clk, for this
add a new compatible samsung,exynos5420-dwusb3 to help configure
dwc3 code and dwc3 suspend clock. Suspend clock controls the PHY power
change from P0 to P1/P2/P3 during U0 to U1/U2/U3 transition.

This patch introduces a new parameter to activate external ID pin and valid
vbus level detection, required on STM32MP15 SoC to support dual role,
either in HS or FS.
The STM32MP15 SoC uses the GGPIO register to enable the level detection.
The level detector requires to be powered.
Also adds the params structures for STM32MP15 OTG HS and STM32MP1 OTG FS.

Depending on the current link state the steps to resume the link to U0
varies. The normal case when a port is suspended (U3) we set the link
to U0 and wait for a port event when U3exit completed and port moved to
U0.
If the port is in U1/U2, then no event is issued, just set link to U0
If port is in Resume or Recovery state then the device has already
initiated resume, and this host initiated resume is racing against it.
Port event handler for device initiated resume will set link to U0,
just wait for the port to reach U0 before returning.

Like U3 case, xHCI spec doesn't specify the upper bound of U0 transition
time. The 20ms is not enough for some devices.
Intead of polling PLS or PLC, we can facilitate the port change event to
know that the link transits to U0 is completed.
While at it, also separate U0 and U3 case to make the code cleaner.

The xHCI spec doesn't specify the upper bound of U3 transition time. For
some devices 20ms is not enough, so we need to make sure the link state
is in U3 before further actions.
I've tried to use U3 Entry Capability by setting U3 Entry Enable in
config register, however the port change event for U3 transition
interrupts the system suspend process.
For now let's use the less ideal method by polling PLS.
[use usleep_range(), and shorten the delay time while polling -Mathias]

Don't show the same error message for transaction errors and split
transaction errors. It's very confusing while debugging.
Transaction errors are often due to electrical interference.
Split transaction errors are about xHC not being able to

low- and full-speed devices behind high-speed hubs.

Bail out early if the xHC host needs to be reset at resume
but driver can't access xHC PCI registers.
If xhci driver already fails to reset the controller then there
is no point in attempting to free, re-initialize, re-allocate and
re-start the host. If failure to access the host is detected later,
failing the resume, xhci interrupts will be double freed
when remove is called.

Turns out the undocumented and reserved bits of port status/control
register of the root port need to be set to use the HCI in HSIC mode.
Typically the firmware does this, but that is not always good enough,
because the bits get lost if the HSIC clock is disabled (e.g. when
ehci-mv is build as a module).
This supplements commit 7b104f890ade ("USB: EHCI: ehci-mv: add HSIC
support").

NVIDIA VirtualLink (svid 0x955) has two altmode, vdo=0x1 for
VirtualLink DP mode and vdo=0x3 for NVIDIA test mode. NVIDIA
test device FTB (Function Test Board) reports altmode list with
vdo=0x3 first and then vdo=0x1. The list is:
SVID VDO
0xff01 0xc05
0x28de 0x8085
0x955 0x3
0x955 0x1
Current logic to assign mode value is based on order
in altmode list. This causes a mismatch of CON and SOP altmodes
since NVIDIA GPU connector has order of vdo=0x1 first and then
vdo=0x3. Fixing this by changing the order of vdo values
reported by NVIDIA test device. the new list will be:
SVID VDO
0xff01 0xc05
0x28de 0x8085
0x955 0x1085
0x955 0x3
Also NVIDIA VirtualLink (svid 0x955) uses pin E for display mode.
NVIDIA test device reports vdo of 0x1 so make sure vdo values
always have pin E assignement.

Pull ARM SoC fixes from Olof Johansson:
"We've been accruing these for a couple of weeks, so the batch is a bit
bigger than usual.
Largest delta is due to a led-bl driver that is added -- there was a
miscommunication before the merge window and the driver didn't make it
in. Due to this, the platforms needing it regressed. At this point, it
seemed easier to add the new driver than unwind the changes.
Besides that, there are a handful of various fixes:
- AMD tee memory leak fix
- A handful of fixlets for i.MX SCU communication
- A few maintainers woke up and realized DEBUG_FS had been missing
for a while, so a few updates of that.

There is a recipe to deadlock the kernel: submit a timeout sqe with a
linked_timeout (e.g. test_single_link_timeout_ception() from liburing),
and SIGKILL the process.
Then, io_kill_timeouts() takes @ctx->completion_lock, but the timeout
isn't flagged with REQ_F_COMP_LOCKED, and will try to double grab it
during io_put_free() to cancel the linked timeout. Probably, the same
can happen with another io_kill_timeout() call site, that is
io_commit_cqring().

- Fix panic in gup_fast on large pud by providing an implementation of
pud_write. This has been overlooked during migration to common gup
code.
- Fix unexpected write combining on PCI stores.

Pull powerpc fixes from Michael Ellerman:
"Some more powerpc fixes for 5.6:
- One fix for a recent regression to our breakpoint/watchpoint code.
- Another fix for our KUAP support, this time a missing annotation in
a rarely used path in signal handling.
- A fix for our handling of a CPU feature that effects the PMU, when
booting guests in some configurations.
- A minor fix to our linker script to explicitly include the .BTF
section.

Bras, Naveen N. Rao, Ravi Bangoria, Stefan Berger"

Pull sound fixes from Takashi Iwai:
"The regular "bump-in-the-middle" updates, containing mostly ASoC-
related fixes at this time. All changes are reasonably small.
A few entries are for ASoC and ALSA core parts (DAPM, PCM, topology)
for followups of the recent changes and potential buffer overflow by
snprintf(), while the rest are (both new and old) device-specific
fixes for Intel, meson, tas2562, rt1015, as well as the usual HD-audio
quirks"

ASoC: Fixes for v5.6
More fixes that have arrived since the merge window, spread out all
over. There's a few things like the operation callback addition for
rt1015 and the meson reset addition which add small new bits of
functionality to fix non-working systems, they're all very small and for
parts of newly added functionality.

git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest
Pull kselftest update from Shuah Khan:
"This consists of a cleanup patch to undo changes to global .gitignore
that added selftests/lkdtm objects and add them to a local
selftests/lkdtm/.gitignore.
Summary of Linus's comments on local vs. global gitignore scope:
- Keep local gitignore patterns in local files.
- Put only global gitignore patterns in the top-level gitignore file.
Local scope keeps things much better separated. It also incidentally
means that if a directory gets renamed, the gitignore file continues
to work unless in the case of renaming the actual files themselves
that are named in the gitignore"

by NOMMU.

to run on QEMU's virt platform.
- DTS updates for SiFive's HiFive Unleashed.
