f07a360813 thunderbolt: Introduce tb_switch_is_icm()
We currently differentiate between SW CM (Software Connection Manager,
sometimes also called External Connection Manager) and ICM (Firmware
based Connection Manager, Internal Connection Manager) by looking
directly at the sw->config.enabled field which may be rather hard to
understand for the casual reader. For this reason introduce a wrapper
function with documentation that should make the intention more clear.

preserve compatibility with the definitions for R-Car M3-W (R8A77960).

Note that internal CPG clocks (S0, S1, S2, S3, SDSRC, SSPSRC, and POST2)
are not included, as they are used as internal clock sources only, and
never referenced from DT.

The Broadcom Brahma-B53 core is susceptible to the issue described by
ARM64_ERRATUM_843419 so this commit enables the workaround to be applied

Since there are now multiple entries to match, we must convert the
existing ARM64_ERRATUM_843419 into an erratum list and use
cpucap_multi_entry_cap_matches to match our entries.

e5661c6ab0 drm/i915/selftests: Start kthreads before stopping
An interesting observation made with our parallel selftests was that on
our small/single cpu systems we would call kthread_stop() before the
kthreads were spawned. If this happens, the kthread is never run at all;
completely bypassing the test.

A simple yield() from the parent will ensure that all children have the
opportunity to start before we reap them.

3ae82f449c drivers/staging/exfat: Replace binary semaphores for mutexes
At a slight footprint cost (24 vs 32 bytes), mutexes are more optimal
than semaphores; it's also a nicer interface for mutual exclusion,
which is why they are encouraged over binary semaphores, when possible.

For both v_sem and z_sem, their semantics imply traditional lock
ownership; that is, the lock owner is the same for both lock/unlock
operations. Therefore it is safe to convert.

84db889e6d drm/tegra: Unconditionally select IOMMU_IOVA
Currently configurations can be generated where IOMMU_SUPPORT is
disabled but IOMMU_IOVA is built as a module and DRM_TEGRA as built-in.
In such a case, the symbols guarded by IOMMU_IOVA will not be available
when linking the Tegra DRM driver and cause a linking failure.

Simplify this by unconditionally selecting IOMMU_IOVA, which makes sure
that it will be forced to =y if DRM_TEGRA=y. Technically we can now get
IOMMU_IOVA code built-in even if we don't use it (Tegra DRM only uses it
when IOMMU_SUPPORT is also enabled), but such configuration are of a
mostly academic nature. In all practical configurations we want IOMMU
support anyway.

ebc8f4f603 Second set of IIO + counter new device support, features etc for the 5.5 cycle.
Note two merge commits in here, both for immutable branches based
 of 5.4-rc1.
 1. Ti eqep driver because of some file moves in precursor patches.
    I suspect no one else will pull this one.
 2. ab8500 refactor as changes in power supply, hwmon and mfd trees.
    This may come via numerous trees as well as IIO.
 
 Counter subsystem related
 * ti eqep
   - New device support with bindings.
   - Includes prior file move to reflect more general use of ti-pwmss.
 * Counter core
   - simplify count_read and count_write callbacks + document change.
   - fix a typo in docs.
 
 Various subsystems related
 * AB8500
   - ab8500_btemp driver converted to be an IIO consumer driver.
   - ab8500_charger driver converted to be an IIO consumer driver.
   - ab8500_fg fuel gauge driver converted to be an IIO consumer driver.
   - ab8500 hwmon driver converted to be an IIO consumer driver.
   - mfd bindings augmented with the adc channels to make the above work.
   - drop original mfd driver.
 
 New device support
 * ab8500
   - new ADC driver used by the above other subystems via the IIO consumer
     interface.
 * adux1020 photometric sensor
   - new driver and dt bindings.
 * fxos877cq
   - new driver for this simple(ish) IMU with DT bindings.
 * intel_mrfld_adc
   -  new driver for the ADC found on Intel Merrifield platforms.
 * ltc2983
   - new driver for this multi-sensor type temperature interface.
     Includes complex DT bindings.
 * max1027
   - support for 12 bit devices, max1227, max1229 and max1231 + add to trivial
     bindings.
 * st_lsm6dsx
   - support for the LSM6DS0 6 axis MEMs sensor.
     Note different from the LSM6DSO which the driver already supports *sigh*

Merge tag 'iio-for-5.5b' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Second set of IIO + counter new device support, features etc for the 5.5 cycle.

Note two merge commits in here, both for immutable branches based
of 5.4-rc1.
1. Ti eqep driver because of some file moves in precursor patches.
   I suspect no one else will pull this one.
2. ab8500 refactor as changes in power supply, hwmon and mfd trees.
   This may come via numerous trees as well as IIO.

Counter subsystem related
* ti eqep
  - New device support with bindings.
  - Includes prior file move to reflect more general use of ti-pwmss.
* Counter core
  - simplify count_read and count_write callbacks + document change.
  - fix a typo in docs.

Various subsystems related
* AB8500
  - ab8500_btemp driver converted to be an IIO consumer driver.
  - ab8500_charger driver converted to be an IIO consumer driver.
  - ab8500_fg fuel gauge driver converted to be an IIO consumer driver.
  - ab8500 hwmon driver converted to be an IIO consumer driver.
  - mfd bindings augmented with the adc channels to make the above work.
  - drop original mfd driver.

New device support
* ab8500
  - new ADC driver used by the above other subystems via the IIO consumer
    interface.
* adux1020 photometric sensor
  - new driver and dt bindings.
* fxos877cq
  - new driver for this simple(ish) IMU with DT bindings.
* intel_mrfld_adc
  -  new driver for the ADC found on Intel Merrifield platforms.
* ltc2983
  - new driver for this multi-sensor type temperature interface.
    Includes complex DT bindings.
* max1027
  - support for 12 bit devices, max1227, max1229 and max1231 + add to trivial
    bindings.
* st_lsm6dsx
  - support for the LSM6DS0 6 axis MEMs sensor.
    Note different from the LSM6DSO which the driver already supports *sigh*
  - support for the LSM6DSRX 6 axis MEMs sensor.

Features and cleanups
* ad7303
  - replace use of core mlock with a local lock with cleanly defined scope.
