Pull USB fixes from Greg KH:
"Here are a lot of small USB driver fixes for 5.4-rc3.
syzbot has stepped up its testing of the USB driver stack, now able to
trigger fun race conditions between disconnect and probe functions.
Because of that we have a lot of fixes in here from Johan and others
fixing these reported issues that have been around since almost all
time.
We also are just deleting the rio500 driver, making all of the syzbot
bugs found in it moot as it turns out no one has been using it for
years as there is a userspace version that is being used instead.
There are also a number of other small fixes in here, all resolving
reported issues or regressions.
All have been in linux-next without any reported issues"

The Rio500 kernel driver has not been used by Rio500 owners since 2001
not long after the rio500 project added support for a user-space USB stack
through the very first versions of usbdevfs and then libusb.
Support for the kernel driver was removed from the upstream utilities

Fixes for omaps for v5.4-rc cycle
Here are fixes for omaps to deal with few regressions, and to fix
more boot time errors and warnings:
- The recent ti-sysc interconnect target module driver changes had
incorrect clock bits for both clocks and dts that cause warnings
- For omap3-gta04, gpio changes caused the LCD to break a while back,
and after discussing things the right fix is to set spi-cs-high
- Recent omapdrm changes to use generic panels caused tfp410 to be
disabled as we now must enable the generic support for it in
defconfig
- Recent omapdrm and backlight changes also finally made droid4 LCD
to work, so let's enable it in the defconfig it can be used out
of the box. This is not strictly a fix, but we still also have the
older CONFIG_MFD_TI_LMU options available so this cuts down the
confusion for trying to guess which display and which backlight
is needed
- Recent ti-sysc interconnect target module changes need the gpio
module disabled on some boards, but this now needs to happen at
the module level, not at the gpio driver level
- Recent changes to probe system timers with ti-sysc caused warnings
about mismatch in syconfig registers, so let's configure the option
for RESET_STATUS as available in the TRMs
- Recent changes to probe LCDC with ti-sysc caused warnings about
mismatch in sysconfig registers, so let's configure the missing
idlemodes for both platform data and dts as documented in TRMs
- Since we moved mach-omap2 to probe with device tree, we've been
getting voltage controller warnings. Turns out this code is no
longer needed, so let's just remove omap2_set_init_voltage() to
get rid of the pointless warnings
- Configure am4372 dispc memory bandwidth to avoid underflow errors

Today the EFI runtime functions are setup in architecture specific
code (x86 and arm), with the functions themselves living in drivers/xen
as they are not architecture dependent.
As the setup is exactly the same for arm and x86 move the setup to
drivers/xen, too. This at once removes the need to make the single
functions global visible.

The NEON/Crypto Extensions based AES implementation for 32-bit ARM
can be built in a kernel that targets ARMv6 CPUs and higher, even
though the actual code will not be able to run on that generation,
but it allows for a portable image to be generated that can will
use the special instructions only when they are available.
Since those instructions are part of a FPU profile rather than a
CPU profile, we don't override the architecture in the assembler
code, and most of the scalar code is simple enough to be ARMv6
compatible. However, that changes with commit c61b1607ed4fbbf2,
which introduces calls to the movw/movt instructions, which are
v7+ only.
So override the architecture in the .S file to armv8-a, which
matches the architecture specification in the crypto-neon-fp-armv8
FPU specificier that we already using. Note that using armv7-a
here may trigger an issue with the upcoming Clang 10 release,
which no longer permits .arch/.fpu combinations it views as
incompatible.

The naming of pgtable_page_{ctor,dtor}() seems to have confused a few
people, and until recently arm64 used these erroneously/pointlessly for
other levels of page table.
To make it incredibly clear that these only apply to the PTE level, and to
align with the naming of pgtable_pmd_page_{ctor,dtor}(), let's rename them
to pgtable_pte_page_{ctor,dtor}().
These changes were generated with the following shell script:
----
git grep -lw 'pgtable_page_.tor' | while read FILE; do
sed -i '{s/pgtable_page_ctor/pgtable_pte_page_ctor/}' $FILE;
sed -i '{s/pgtable_page_dtor/pgtable_pte_page_dtor/}' $FILE;
done
----
... with the documentation re-flowed to remain under 80 columns, and
whitespace fixed up in macros to keep backslashes aligned.
There should be no functional change as a result of this patch.

This code is currently unable to find the dts opp tables as ti-cpufreq
needs to set them up first based on speed binning.
We stopped initializing the opp tables with platform code years ago for
device tree based booting with commit 92d51856d740 ("ARM: OMAP3+: do not
register non-dt OPP tables for device tree boot"), and all of mach-omap2
is now booting using device tree.
We currently get the following errors on init:
omap2_set_init_voltage: unable to find boot up OPP for vdd_mpu
omap2_set_init_voltage: unable to set vdd_mpu
omap2_set_init_voltage: unable to find boot up OPP for vdd_core

to initialize things properly.

TRM "Table 13-34. SYSCONFIG Register Field Descriptions" lists both
standbymode and idlemode that should be just the sidle and midle
registers where midle is currently unconfigured for lcdc_sysc. As
the dts data has been generated based on lcdc_sysc, we now have an
empty "ti,sysc-midle" property.
And so we currently get a warning for lcdc because of a difference
with dts provided configuration compared to the legacy platform
data. This is because lcdc has SYSC_HAS_MIDLEMODE configured in
the platform data without configuring the modes.
Let's fix the issue by adding the missing midlemode to lcdc_sysc,
and configuring the "ti,sysc-midle" property based on the TRM
values.

For ti,sysc-omap4 compatible devices with no sysstatus register, we do have
reset done status available in the SOFTRESET bit that clears when the reset
is done. This is documented for example in am437x TRM for DMTIMER_TIOCP_CFG
register. The am335x TRM just says that SOFTRESET bit value 1 means reset is
ongoing, but it behaves the same way clearing after reset is done.
With the ti-sysc driver handling this automatically based on no sysstatus
register defined, we see warnings if SYSC_HAS_RESET_STATUS is missing in the
legacy platform data:
ti-sysc 48042000.target-module: sysc_flags 00000222 != 00000022
ti-sysc 48044000.target-module: sysc_flags 00000222 != 00000022
ti-sysc 48046000.target-module: sysc_flags 00000222 != 00000022
...
Let's fix these warnings by adding SYSC_HAS_RESET_STATUS. Let's also
remove the useless parentheses while at it.
If it turns out we do have ti,sysc-omap4 compatible devices without a
working SOFTRESET bit we can set up additional quirk handling for it.

arm uses a top-down mmap layout by default that exactly fits the generic
functions, so get rid of arch specific code and use the generic version by
selecting ARCH_WANT_DEFAULT_TOPDOWN_MMAP_LAYOUT.
As ARCH_WANT_DEFAULT_TOPDOWN_MMAP_LAYOUT selects ARCH_HAS_ELF_RANDOMIZE,
use the generic version of arch_randomize_brk since it also fits. Note
that this commit also removes the possibility for arm to have elf
randomization and no MMU: without MMU, the security added by randomization
is worth nothing.
Note that it is safe to remove STACK_RND_MASK since it matches the default
value.

Both pgtable_cache_init() and pgd_cache_init() are used to initialize kmem
cache for page table allocations on several architectures that do not use
PAGE_SIZE tables for one or more levels of the page table hierarchy.
Most architectures do not implement these functions and use __weak default
NOP implementation of pgd_cache_init(). Since there is no such default
for pgtable_cache_init(), its empty stub is duplicated among most
architectures.
Rename the definitions of pgd_cache_init() to pgtable_cache_init() and
drop empty stubs of pgtable_cache_init().

Patch series "mm: remove quicklist page table caches".
A while ago Nicholas proposed to remove quicklist page table caches [1].
I've rebased his patch on the curren upstream and switched ia64 and sh to
use generic versions of PTE allocation.
[1] https://lore.kernel.org/linux-mm/20190711030339.20892-1-npiggin@gmail.com
This patch (of 3):
Remove page table allocator "quicklists". These have been around for a
long time, but have not got much traction in the last decade and are only
used on ia64 and sh architectures.
The numbers in the initial commit look interesting but probably don't
apply anymore. If anybody wants to resurrect this it's in the git
history, but it's unhelpful to have this code and divergent allocator
behaviour for minor archs.
Also it might be better to instead make more general improvements to page
allocator if this is still so slow.

commit 6953c57ab172 "gpio: of: Handle SPI chipselect legacy bindings"
did introduce logic to centrally handle the legacy spi-cs-high property
in combination with cs-gpios. This assumes that the polarity
of the CS has to be inverted if spi-cs-high is missing, even
and especially if non-legacy GPIO_ACTIVE_HIGH is specified.
The DTS for the GTA04 was orginally introduced under the assumption
that there is no need for spi-cs-high if the gpio is defined with
proper polarity GPIO_ACTIVE_HIGH.
This was not a problem until gpiolib changed the interpretation of
GPIO_ACTIVE_HIGH and missing spi-cs-high.
The effect is that the missing spi-cs-high is now interpreted as CS being
low (despite GPIO_ACTIVE_HIGH) which turns off the SPI interface when the
panel is to be programmed by the panel driver.
Therefore, we have to add the redundant and legacy spi-cs-high property
to properly activate CS.

Also the mcasp clkctrl clock bits are wrong:
For mcasp1 and 2 we have four clocks at bits 28, 24, 22 and 0:
bit 28 is ahclkr
bit 24 is ahclkx
bit 22 is auxclk
bit 0 is fck
For mcasp3 to 8 we have three clocks at bits 24, 22 and 0.

bit 0 is fck
We do not have currently mapped auxclk at bit 22 for the drivers, that can

Pull ARM SoC late updates from Arnd Bergmann:
"This is some material that we picked up into our tree late or that had
complex inter-depondencies. The fact that there are these
interdependencies tends to meant that these are often actually the
most interesting new additions:
- The new Aspeed AST2600 baseboard management controller is added,
this is a Cortex-A7 based follow-up to the ARM11 based AST2500 and
had some dependencies on other device drivers.
- After many years, support for the MMP2 based OLPC XO-1.75 finally
makes it into the kernel.
- The Armada 3720 based Turris Mox open source router platform is a
late addition and it follows some preparatory work across multiple
branches.
- The OMAP2+ platform had some large-scale cleanup involving driver
changes and DT changes, here we finish it off, dropping a lot of
the now-unused platform data.
- The TI K3 platform that got added for 5.3 gains a lot more support
for individual bits on the SoC, this part just came late for the
merge window"

Linux supports both the original ARMv6 level (early ARM1136) and ARMv6K
(later ARM1136, ARM1176 and ARM11mpcore).
ast2500 falls into the second categoy, being based on arm1176jzf-s.
This is enabled by default when using ARCH_MULTI_V6, so we should
not 'select CPU_V6'.
Removing this will lead to more efficient use of atomic instructions.

Two major chunks of code are moving out of the tree and into the

Pull sound updates from Takashi Iwai:
"As shown in diffstat and logs, it was again a busy development cycle
at this time, too. The most significant changes are still on-going
refactoring / modernization works for ASoC core and drivers, but there
are lots of other changes as well. Here we go, some highlights below:
ASoC:
- Quite a lot of cleanup / refactoring of ASoC core and APIs; most of
them are systematic, but also including cleanups and modernization
- A bulk of updates for some ASoC platforms, Freescale, sunxi and
Intel SST/SOF
- Initial support for Sound Open Firmware on i.MX8
- Removal of deprecated w90x900 and nuc900 drivers
- New support for Cirrus Logic CS47L15 and CS47L92, Freescale i.MX
7ULP and 8MQ, Meson G12A and NXP UDA1334
USB-audio:
- More validations of descriptor units for hardening against bugs
reported by fuzzers
- PCM device assignment workaround for a past call-order change
- Scarlett Gen2 mixer interface, a few more more quirks
HD-audio:
- Support for audio component with AMD/ATI and Nvidia HDMI codecs
- Clean up HD-audio core and remove indirect access ops for Intel SOF
- DMIC detection at probe; it would make systems automatically
falling back to SST/SOF driver on devices that need DMIC handling.
Needs a new Kconfig to set, and beware that it's still new and a
bit experimental
FireWire:
- Lots of code refactoring and cleanups"

Pull core irq updates from Thomas Gleixner:
"Updates from the irq departement:
- Update the interrupt spreading code so it handles numa node with
different CPU counts properly.
- A large overhaul of the ARM GiCv3 driver to support new PPI and SPI
ranges.
- Conversion of all alloc_fwnode() users to use physical addresses
instead of virtual addresses so the virtual addresses are not
leaked. The physical address is sufficient to identify the
associated interrupt chip.
- Add support for Marvel MMP3, Amlogic Meson SM1 interrupt chips.
- Enforce interrupt threading at compile time if RT is enabled.
- Small updates and improvements all over the place"
