3ae6156e2f arm64: dts: qcom: msm8998-mtp: Merge and fix up the DT
Merge the two DT files into one, sort the nodes and fix up a couple of style
incoherencies by adding some newlines, removing some, sorting properties etc.

d0eaf4122c arm64: dts: qcom: msm8998-fxtec: Decouple from 8998 MTP
While the Pro-1 is based on MTP and is very close to it, it's really not great
for it to include the MTP dtsi straight up, as any small change will affect
both boards and not all of them will apply to the phone as well.

392b73cb81 arm64: dts: qcom: msm8998*: Keep MMCC & MMSS_SMMU enabled by default
MMCC is a component of the SoC that should always be configured. It was kept
off due to misconfiguration on clamshell machines. Keep it disabled on these
ones and enable it by default on all the others.

Exactly the same story applies to MMSS_SMMU, which directly depends on MMCC.

Do note, that if a platform doesn't use neither EFIFB (only applies to WoA
devices in this case) or simplefb (applies to precisely 2 msm8998 devices
as of this commit), this will not cause any harm.

d756a0b29f arm64: dts: qcom: sc7280: Set SPI flash to 50 MHz for herobrine boards
sc7280-herobrine based boards are specced to be able to access their
SPI flash at 50 MHz with the drive strength of the pins set at 8. The
drive strength is already set to 8 in "sc7280-herobrine.dtsi", so
let's bump up the clock. The matching firmware change for this is at:

https://review.coreboot.org/c/coreboot/+/63948

NOTE: the firmware change isn't _required_ to make the kernel work at
50 MHz, it merely shows that the boards are known to work fine at 50
MHz.

ALSO NOTE: this doesn't update the "sc7280-chrome-common.dtsi" file
which is used by both herobrine boards and IDP. At the moment the IDP
boards aren't configuring a drive strength of 8 and it seems safer to
just leave them at the slower speed if they're already working.

e58539532b arm64: dts: qcom: sc7280: Add touchscreen to villager
This adds the touchscreen to the sc7280-herobrine-villager device
tree. Note that the touchscreen on villager actually uses the reset
line and thus we use the more specific "elan,ekth6915" compatible
which allows us to specify the reset.

The fact that villager's touchscreen uses the reset line can be
contrasted against the touchscreen for CRD/herobrine-r1. On those
boards, even though the touchscreen goes to the display, it's not
hooked up to anything there.

In order to keep the line parked on herobrine/CRD, we'll move the
pullup from the qcard.dtsi file to the specific boards. This allows us
to disable the pullup in the villager device tree since the pin is an
output.

372b2aee97 arm64: dts: qcom: Remove duplicate sc7180-trogdor include on lazor/homestar
The sc7180-trogdor-{lazor,homestar}-*.dtsi files all include
sc7180-trogdor.dtsi and sc7180-trogdor-lazor.dtsi or
sc7180-trogdor-homestar.dtsi, so including it here in the
sc7180-trogdor-{lazor,homestar}.dtsi file means we have a duplicate
include after commit 19794489fa24 ("arm64: dts: qcom: Only include
sc7180.dtsi in sc7180-trogdor.dtsi"). We include the sc7180-trogdor.dtsi
file in a board like sc7180-trogdor-lazor-r1.dts so that we can include
the display bridge snippet (e.g. sc7180-trogdor-ti-sn65dsi86.dtsi)
instead of making ever increasing variants like
sc7180-trogdor-lazor-ti-sn65dsi86.dtsi.

Unfortunately, having the double include like this means the display
bridge's i2c bus is left disabled instead of enabled by the bridge
snippet. Any boards that use the i2c bus for the display bridge will
have the bus disabled when we include sc7180-trogdor.dtsi the second
time, which picks up the i2c status="disabled" line from sc7180.dtsi.
This leads to the display not turning on and black screens at boot on
lazor and homestar devices.

Fix this by dropping the include and making a note that the
sc7180-trogdor-{lazor,homestar}.dtsi file must be included after
sc7180-trogdor.dtsi

1ec6574a3c This set of changes updates init and user mode helper tasks to be
ordinary user mode tasks.
 
 In commit 40966e316f86 ("kthread: Ensure struct kthread is present for
 all kthreads") caused init and the user mode helper threads that call
 kernel_execve to have struct kthread allocated for them.  This struct
 kthread going away during execve in turned made a use after free of
 struct kthread possible.
 
 The commit 343f4c49f243 ("kthread: Don't allocate kthread_struct for
 init and umh") is enough to fix the use after free and is simple enough
 to be backportable.
 
 The rest of the changes pass struct kernel_clone_args to clean things
 up and cause the code to make sense.
 
 In making init and the user mode helpers tasks purely user mode tasks
 I ran into two complications.  The function task_tick_numa was
 detecting tasks without an mm by testing for the presence of
 PF_KTHREAD.  The initramfs code in populate_initrd_image was using
 flush_delayed_fput to ensuere the closing of all it's file descriptors
 was complete, and flush_delayed_fput does not work in a userspace thread.
 
 I have looked and looked and more complications and in my code review
 I have not found any, and neither has anyone else with the code sitting

54c2cc7919 USB / Thunderbolt changes for 5.19-rc1
Here is the "big" set of USB and Thunderbolt driver changes for
 5.18-rc1.  For the most part it's been a quiet development cycle for the
 USB core, but there are the usual "hot spots" of development activity.
 
 Included in here are:
 	- Thunderbolt driver updates:
 		- fixes for devices without displayport adapters
 		- lane bonding support and improvements
 		- other minor changes based on device testing
 	- dwc3 gadget driver changes.  It seems this driver will never
 	  be finished given that the IP core is showing up in zillions
 	  of new devices and each implementation decides to do something
 	  different with it...
 	- uvc gadget driver updates as more devices start to use and
 	  rely on this hardware as well
 	- usb_maxpacket() api changes to remove an unneeded and unused
 	  parameter.
 	- usb-serial driver device id updates and small cleanups
 	- typec cleanups and fixes based on device testing
 	- device tree updates for usb properties
 	- lots of other small fixes and driver updates.
 
 All of these have been in linux-next for weeks with no reported
 problems.

Merge tag 'usb-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB / Thunderbolt updates from Greg KH:
 "Here is the "big" set of USB and Thunderbolt driver changes for
  5.18-rc1. For the most part it's been a quiet development cycle for
  the USB core, but there are the usual "hot spots" of development
  activity.

  Included in here are:

   - Thunderbolt driver updates:
       - fixes for devices without displayport adapters
       - lane bonding support and improvements
       - other minor changes based on device testing

   - dwc3 gadget driver changes.

     It seems this driver will never be finished given that the IP core
     is showing up in zillions of new devices and each implementation
     decides to do something different with it...

   - uvc gadget driver updates as more devices start to use and rely on
     this hardware as well

   - usb_maxpacket() api changes to remove an unneeded and unused
     parameter.

   - usb-serial driver device id updates and small cleanups

   - typec cleanups and fixes based on device testing

   - device tree updates for usb properties

   - lots of other small fixes and driver updates.

  All of these have been in linux-next for weeks with no reported
  problems"

09a018176b ARM: SoC changes, part 2
This is the second part of the general SoC updates, containing
 everything that did not make it in the initial pull request,
 or that came in as a bugfix later.
 
  - Devicetree updates for SoCFPGA, ASPEED, AT91 and Rockchip, including
    a new machine using an ASPEED BMC.
 
  - More DT fixes from Krzysztof Kozlowski across platforms
 
  - A new SoC platform for the GXP baseboard management controller,
    used in current server products from HPE.

73e2d827a5 arm64: Initialize jump labels before setup_machine_fdt()
A static key warning splat appears during early boot on arm64 systems
that credit randomness from devicetrees that contain an "rng-seed"
property. This is because setup_machine_fdt() is called before
jump_label_init() during setup_arch(). Let's swap the order of these two
calls so that jump labels are initialized before the devicetree is
unflattened and the rng seed is credited.

 static_key_enable_cpuslocked(): static key '0xffffffe51c6fcfc0' used before call to jump_label_init()
