First set of IIO new device support, cleanups and features for the 5.5 cycle
Third version with the adis rework set dropped as better to just have
a fresh version of that at some future date.
The usual mixed backs of new device support being added to drivers,
long term reworks continuing and little per driver cleanups and
features.
Also a few trivial counter subsystem tidy ups on behalf of William.
Core new feature
* Device label support. A long requested feature no one got around to
implementing before. Allows DT based provision of a 'label' that
identifies a device uniquely within a system. This differs from existing
'name' which is meant to be the part number.
New device support
* ingenic-adc
- Support for the JZ4770 SoC ADC including bindings.
* inv_mpu6050
- Add support for magnetometer in MPU925x parts.
Fiddly to do as this is actually a separate device sitting inside the
package, but with the master device being able to schedule reads etc.
Will only run if the auxiliary bus is not in use for any other devices.
Features
* ad7192
- Userspace calibration controls to do zero and full scale.
* st_lsm6dsx
- Enable latched interrupts by default for sensors events with related clear.
- Motion events and related wakeup source. This needed quite a bit of
refactoring as well.
Cleanups and minor features
* ad7192
- sysfs ABI docs
* ad7949
- Remove code to readback configuration word as driver never actually enabled
it.
- Fix incorrect xfer length. Not actually known to cause problems other
than wasted bus usage.
* adis16080
- Replace core mlock usage with local lock with more appropriate scope.
* adis16130
- Remove pointless mlock usage.
* adis16240
- Remove include of gpio.h as no gpio usage.
* atlas-ph-sensor
- Improve logical ordering of buffer predisable / postenable functions.
This is part of a longer term rework Alexandru is driving towards.
* bh1750
- Fix up a static compiler warning and make the code more readable.
- yaml conversion of binding + MAINTAINERS entry.
* bmp280
- Drop a stray newline.
* cm36651
- Drop a redundant assignment
* itg3200
- Alignment cleanup.
* max31856
- Add missing of_node and parent references, useful to identify the device.
* sc27xx_adc
- Use devm_hwspin_lock_request_specific rather than local rolled version.
* stm32-lptimer counter
- kernel-doc warning.
* stm32-timer counter
- kernel-doc warning.
- Alignment cleanup.
* sx9500
- Improve logical ordering of buffer predisable / postenable functions.
This is part of a longer term rework Alexandru is driving towards.

staging: rtl8723bs: Fix incorrect type in declaration
Fix incorrect type in declaration to solve the warnings 'incorrect
type in argument 2' in the rtw_get_wpa_ie and rtw_get_wpa_ie function
calls, as both expect the same variable in argument 2 with the
type int *.
Issue found by Sparse.
The rtl8723bs driver tries to load various parameters from disk,
circumventing the standard firmware loader mechanism and using DIY
code for this.
No devices which run the mainline kernel ship with these files and even
if these files were present then they still would not be loaded without
additional module parameters. To be precise the following 3 conditions
must all 3 be true for on disk parameters to be used:
1) The rtw_load_phy_file modparam must contain the mask for the type, this
defaults to(LOAD_BB_PG_PARA_FILE | LOAD_RF_TXPWR_LMT_PARA_FILE) so with
the default settings this condition is only true for:
phy_ConfigBBWithPgParaFile()
PHY_ConfigRFWithPowerLimitTableParaFile(); and
2) rtw_phy_file_path modparam must be set to say "/lib/firmware/"; and
3) Store a /lib/firmware/rtl8723b/XXX file in the expected format.
In practice all 3 being true never happens, so the
phy_Config*With*ParaFile() calls are nops, remove them.
The actual code implementing them will be removed in a separate patch.
Note the ODM_ConfigRFWithHeaderFile() and ODM_ConfigBBWithHeaderFile()
functions always return HAL_STATUS_SUCCESS, this patch makes use of this
to simplify the new code without the phy_Config*With*ParaFile() calls.

staging/octeon: Use stubs for MIPS && !CAVIUM_OCTEON_SOC
When building for a non-Cavium MIPS system with COMPILE_TEST=y, the
Octeon ethernet driver hits a number of issues due to use of macros
provided only for CONFIG_CAVIUM_OCTEON_SOC=y configurations. For
example:
drivers/staging/octeon/ethernet-rx.c:190:6: error:
'CONFIG_CAVIUM_OCTEON_CVMSEG_SIZE' undeclared (first use in this function)
drivers/staging/octeon/ethernet-rx.c:472:25: error:
'OCTEON_IRQ_WORKQ0' undeclared (first use in this function)
These come from various asm/ headers that a non-Octeon build will be
using a non-Octeon version of.
Fix this by using the octeon-stubs.h header for non-Cavium MIPS builds,
and only using the real asm/octeon/ headers when building a Cavium
Octeon kernel configuration.
This requires that octeon-stubs.h doesn't redefine XKPHYS_TO_PHYS, which
is defined for MIPS by asm/addrspace.h which is pulled in by many other
common asm/ headers.

iio: imu: st_lsm6dsx: add motion report function and call from interrupt
Report iio motion events to iio subsystem and filter motion events.
Wakeup will still be on all channels as it's not possible to do the filtering
