Linux 5.5

wireless-drivers-next patches for v5.6

Second set of patches for v5.6. Nothing special standing out, smaller
new features and fixes allover.

Major changes:

ar5523

* add support for SMCWUSBT-G2 USB device

iwlwifi

* support new versions of the FTM FW APIs

* support new version of the beacon template FW API

* print some extra information when the driver is loaded

rtw88

* support wowlan feature for 8822c

* add support for WIPHY_WOWLAN_NET_DETECT

brcmfmac

* add initial support for monitor mode

qtnfmac

* add module parameter to enable DFS offloading in firmware

* add support for STA HE rates

* add support for TWT responder and spatial reuse

This is the 5.4.15 stable release

amd-drm-fixes-5.5-2020-01-23:

amdgpu:
- remove the experimental flag from renoir

Power management fix for 5.5-rc8

Prevent the kernel from crashing during resume from hibernation
if free pages contain leftover data from the restore kernel and
init_on_free is set (Alexander Potapenko).

wireless-drivers fixes for v5.5

Second set of fixes for v5.5. There are quite a few patches,
especially on iwlwifi, due to me being on a long break. Libertas also
has a security fix and mt76 a build fix.

iwlwifi

* don't send the PPAG command when PPAG is disabled, since it can cause problems

* a few fixes for a HW bug

* a fix for RS offload;

* a fix for 3168 devices where the NVM tables where the wrong tables were being read

* fix a couple of potential memory leaks in TXQ code

* disable L0S states in all hardware since our hardware doesn't
 officially support them anymore (and older versions of the hardware
 had instability in these states)

* remove lar_disable parameter since it has been causing issues for
  some people who erroneously disable it

* force the debug monitor HW to stop also when debug is disabled,
  since it sometimes stays on and prevents low system power states

* don't send IWL_MVM_RXQ_NSSN_SYNC notification due to DMA problems

libertas

* fix two buffer overflows

mt76

* build fix related to CONFIG_MT76_LEDS

* fix off by one in bitrates handling

This is the 5.4.14 stable release

This is the 4.19.98 stable release

This is the 4.14.167 stable release

This is the 4.9.211 stable release

This is the 4.4.211 stable release

Linux 5.5-rc7

Second set of new device support, features and minor fixes for IIO in the 5.6 cycle

Just a small set this time.

As we are very near the merge window, I've rolled a few fixes in here
rather than adding noise just before release.  A short delay here will
do little harm.

New device support
* adis16480
  - Add support for adis16490. After earlier rework this is simple ID plus
    chip info.

Features
* kxcjk1013
  - mount matrix support.
* lsm_6dsx
  - mount matrix support.

Cleanups / minor or late breaking fixes
* ad7124
  - add support to ad-sigma-delta and use it in this driver to allow
    the the interrupt type to be IRQF_TRIGGER_LOW unlike most other devices
    using this framework.
* adis
  - use delay structure now available in SPI to handle transfer delays
  - introduce a timeouts structure to allow support of new devices
* ak8975
  - drop platform data support.  No one is using it and it adds complexity.
  - use device_get_match_data rather than open coding much the same thing.
* dht11
  - drop meaningless todo
* at91-samad2_adc
  - switch to dma_request_chan
* altas-sensor
  - add a helper function to compute number of channels.  Needed for new device
    support that is under review.
* bma400
  - add a lower bound check on scale.
* inv_mpu6050
  - add support for temperature data in the fifos for all chips.
  - support an odd situation where a board supports only interrupt triggering
    on both edges.
* st_lsm6dsx
  - check and handle potential error return.
* st_sensors
  - fix some values for the LSM9DS0 which is ever so slightly different from
    other devices using the same whoami value.
  - switch over to generic functions from dt ones, avoiding need for separate
    ACPI support.
* stm32-adc
  - switch to dma_request_chan
  - suppress an error print in deferred probe case.
* stm32-dac
  - drop private data structure element for reset controller as only used in
    probe.
  - reflect more cleanly that the reset controller is optional whilst ensuring
    that if is specified any errors are caught.
* stm32-dfsdm
  - switch to dma_request_chan
  - fix missing application of formatting to single conversions.
  - ensure the sampling rate is updated when the oversampling ratio is changed.

USB driver fixes for 5.5-rc7

Here are some small USB driver and core fixes for 5.5-rc7

There's one fix for hub wakeup issues and a number of small usb-serial
driver fixes and device id updates.

The hub fix has been in linux-next for a while with no reported issues,
and the usb-serial ones have all passed 0-day with no problems.
