73db215119 ARM: dts: imx6/7: sync fsl,stop-mode with current flexcan driver
After this patch we need 2 arguments less for the fsl,stop-mode
property:

| commit d9b081e3fc

| Date:   Sun Jun 14 21:09:20 2020 +0200

| can: flexcan: remove ack_grp and ack_bit handling from driver
|
| Since commit:
|
|  048e3a34a2 can: flexcan: poll MCR_LPM_ACK instead of GPR ACK for stop mode acknowledgment
|
| the driver polls the IP core's internal bit MCR[LPM_ACK] as stop mode
| acknowledge and not the acknowledgment on chip level.
|
| This means the 4th and 5th value of the property "fsl,stop-mode" isn't used
| anymore. This patch removes the used "ack_gpr" and "ack_bit" from the driver.

This patch removes the two last arguments, as they are not needed
anymore.

faa3b6dfd2 ARM: dts: imx6q-icore-ofcap10: Use 10.1" Ampire panel compatible
Adding display timings directly on device tree files make it difficult
to maintain as a same copy of timings may exist on different files or
panel-simple driver.

We have a panel-simple driver for this particular usage so supporting
on this driver will help to use the same timings on any device tree
files if the board mounted on a similar vendor display.

Engicam C.TOUCH OF 10.1" LCD board uses Ampire 10.1" TFT LCD and
it has supported by panel-simple already, so simply use that binding.

Pull SafeSetID updates from Micah Morton:
 "The changes are mostly contained to within the SafeSetID LSM, with the
  exception of a few 1-line changes to change some ns_capable() calls to
  ns_capable_setid() -- causing a flag (CAP_OPT_INSETID) to be set that
  is examined by SafeSetID code and nothing else in the kernel.

  The changes to SafeSetID internally allow for setting up GID
  transition security policies, as already existed for UIDs"

Pull random32 updates from Willy Tarreau:
 "Make prandom_u32() less predictable.

  This is the cleanup of the latest series of prandom_u32
  experimentations consisting in using SipHash instead of Tausworthe to
  produce the randoms used by the network stack.

  The changes to the files were kept minimal, and the controversial
  commit that used to take noise from the fast_pool (f227e3ec3b) was
  reverted. Instead, a dedicated "net_rand_noise" per_cpu variable is
  fed from various sources of activities (networking, scheduling) to
  perturb the SipHash state using fast, non-trivially predictable data,
  instead of keeping it fully deterministic. The goal is essentially to
  make any occasional memory leakage or brute-force attempt useless.

  The resulting code was verified to be very slightly faster on x86_64
  than what is was with the controversial commit above, though this
  remains barely above measurement noise. It was also tested on i386 and
  arm, and build- tested only on arm64"

8058d69905 i2c: core: Restore acpi_walk_dep_device_list() getting called after registering the ACPI i2c devs
Commit 21653a4181 ("i2c: core: Call i2c_acpi_install_space_handler()
before i2c_acpi_register_devices()")'s intention was to only move the
acpi_install_address_space_handler() call to the point before where
the ACPI declared i2c-children of the adapter where instantiated by
i2c_acpi_register_devices().

But i2c_acpi_install_space_handler() had a call to
acpi_walk_dep_device_list() hidden (that is I missed it) at the end
of it, so as an unwanted side-effect now acpi_walk_dep_device_list()
was also being called before i2c_acpi_register_devices().

Move the acpi_walk_dep_device_list() call to the end of
i2c_acpi_register_devices(), so that it is once again called *after*
the i2c_client-s hanging of the adapter have been created.

This fixes the Microsoft Surface Go 2 hanging at boot.

Fixes: 21653a4181 ("i2c: core: Call i2c_acpi_install_space_handler() before i2c_acpi_register_devices()")
