implement trivial propagating callbacks for get_prio_bitmap and
get_tclass_num, extend mlxsw_sp_qdisc_get_prio_bitmap() and
..._get_tclass_num() to handle the lack of the callback as a cue to forward
the request to the parent.

A following patch will enable offloading qdiscs that are deeper than
directly under root qdisc. Currently the topology validation consists of
demanding a root qdisc position for ETS and PRIO. Since RED and TBF are
considered classless, this is enough. In order to prevent some nonsensical
combinations when RED and TBF become classful, introduce a more general
topology validator.

On Spectrum, there are no per-TC TX counters. Instead, mlxsw uses per-prio
counters and aggregates them according to the priomap. Therefore when
priomap changes, the counter base values need to be reset to reflect the
change. Previously, this was only done for the sole child qdisc, but a
following patch makes RED and TBF classful. Thus apply the request to the
whole sub-tree.

Qdisc graft operations have so far been reported at PRIO, ETS and RED, with
RED events ignored, because RED was not considered a classful qdisc. A
following patch will make mlxsw recognize RED and TBF as classful qdiscs,
and thus it is necessary to validate grafting at these qdiscs as well.
Rename the existing graft validator to make it clear that it is a generic
function, and invoke for RED and TBF graft events as well. Drop the
unnecessary PRIO helper and invoke the graft validator directly for PRIO as
well.

Currently ETS and PRIO are the only offloaded classful qdiscs. Since they
are both similar, their destroy handler is the same, and it handles
children destruction itself. But now it is possible to do it generically
for any classful qdisc. Therefore promote the recursive destruction from
the ETS handler to mlxsw_sp_qdisc_destroy(), so that RED and TBF pick it up
in follow-up patches.

Currently when keeping track of qdiscs, mlxsw notes the TC and priomap
corresponding to each qdisc. That is fine currently, as there only ever is
one level of qdiscs to update: the direct children of ETS / PRIO. However
as deeper structures are made offloadable, ETS would need to update these
values for the complete subtree, and interim qdiscs would need to remember
to propagate the value.
Instead, reverse the responsibility: child qdiscs can ask their parent what
their TC and priomap are. ETS / PRIO know the answer right away, or there
are defaults for when the root qdisc does not assign them (e.g. when RED is
used as root qdisc). When RED and TBF become classful, they will simply
forward the request up to their parent.

Maor Maor Gottlieb says:
========================
Use hash to select the affinity port in VF LAG
Current VF LAG architecture is based on QP association with a port.
QP must be created after LAG is enabled to allow association with non-native port.
VM Packets going on slow-path to eSwicth manager (SW path or hairpin) will be transmitted
through a different QP than the VM. This means that Different packets of the same flow might
egress from different physical ports.
This patch-set solves this issue by moving the port selection to be based on the hash function
defined by the bond.
When the device is moved to VF LAG mode, the driver creates TTC (traffic type classifier) flow
tables in order to classify the packet and steer it to the relevant hash function. Similar to what
is done in the mlx5 RSS implementation.
Each rule in the TTC table, forwards the packet to port selection flow table which has one hash
split flow group which contains two "catch all" flow table entries. Each entry point to the
relative uplink port. As shown below:
-------------------
| FT |
TTC rule -> | ----------- |
| FG| FTE --|-|-----> uplink of port #1
| | FTE --|-|-----> uplink of port #2
| ----------- |
-------------------
Hash split flow group is flow group that created as type of HASH_SPLIT and associated with match definer.
The match definer define the fields which included in the hash calculation.
The driver creates the match definer according to the xmit hash policy of the bond driver.
Patches overview:
========================
Minor E-Switch updates:
- Patch #12, dynamic allocation of dest array
- Patch #13, increase number of forward destinations to 32

In order to start deprecating the custom omap_hsmmc.c in favor of the
generic sdhci-omap driver, we need to add support for voltages for earlier
SoCs.
The PBIAS regulator on omap4 and earlier only supports nominal values of
1.8V and 3.0V, while omap5 and later support nominal values of 1.8V and
3.3V IO voltage.
This gets omap4/5 working with sdhci-omap driver.

data related commands can't get any data related interrupts, include data transfer
complete interrupt, data timeout interrupt, data CRC interrupt, data end bit interrupt.
Always trigger software timeout issue. Even reset the USDHC through bits in register
SYS_CTRL (0x2C, bit28 reset tuning, bit26 reset data, bit 25 reset command, bit 24
reset all) can't recover this. From the user's point of view, USDHC stuck, SD can't

First set of IIO new device and feature support for the 5.16 cycle
Counter subsystem changes now sent separately.
This has been a busy cycle, so lots here and a few more stragglers to
come next week.
Big new feature in this cycle is probably output buffer support.
This has been in the works for a very long time so it's great to see
Mihail pick up the challenge and build upon his predecessors work to finally
bring this feature to mainline.
New device support
------------------
* adi,adxl313
- New driver and dt bindings for this low power accelerometer.
* adi,adxl355
- New driver and dt bindings for this accelerometer.
- Later series adds buffer support.
* asahi-kasei,ak8975
- Minor additions to driver to support ak09916
* aspeed,aspeed-adc
- Substantial rework plus feature additions to add support for the
ast2600 including a new dt bindings doc.
* atmel,at91_sama5d2
- Rework and support introduced for the sama7g5 parts.
* maxim,max31865
- New driver and bindings for this RTD temperature sensor chip.
* nxp,imx8qxp
- New driver and bindings for the ADC found on the i.MX 8QuadXPlus Soc.
* senseair,sunrise
- New driver and bindings for this family of carbon dioxide gas sensors.
* sensiron,scd4x
- New driver and bindings for this carbon dioxide gas sensor.
New features
------------
* Output buffer support. Works in a similar fashion to input buffers, but
in this case userspace pushes data into the kfifo which is then drained
to the device when a trigger occurs. Support added to the ad5766 DAC
driver.
* Core, devm_iio_map_array_register() to avoid need for
devm_add_action_or_reset() based cleanup in fully managed allocation
drivers.
* Core iio_push_to_buffers_with_ts_unaligned() function to safely handle a
few drivers where it really hard to ensure the correct data alignment in
an iio_push_to_buffers_with_timestamp() call. Note this uses a bounce
buffer so should be avoided whenever possible. Used in the ti,adc108s102,
invense,mpu3050 and adi,adis16400. This closes the last known set
of drivers with alignment issues at this interface.
* maxim,max1027
- Substantial rework to this driver main target of which was supporting
use of other triggers than it's own EOC interrupt.
- Transfer optimization.
* nxp,fxls8962af
- Threshold even support including using it as a wakeup source.
Cleanups, minor fixes etc
-------------------------
Chances of a common type to multiple drivers:
* devm_ conversion and drop of .remove() callbacks in:
- adi,ad5064
- adi,ad7291
- adi,ad7303
- adi,ad7746
- adi,ad9832
- adi,adis16080
- dialog,da9150-gpadc
- intel,mrfld_adc
- marvell,berlin2
- maxim,max1363
- maxim,max44000
- nuvoton,nau7802
- st_sensors (includes a lot of rework!)
- ti,ads8344
- ti,lp8788
* devm_platform_ioremap_resource() used to reduce boilerplate
- cirrus,ep93xx
- rockchip,saradc
- stm,stm32-dac
* Use dev_err_probe() in more places to both not print on deferred probe and
ensure a reason for the deferral is available for debug purposes.
- adi,ad8801
- capella,cm36651
- linear,ltc1660
- maxim,ds4424
- maxim,max5821
- microchip,mcp4922
- nxp,lpc18xx
- onnn,noa1305
- st,lsm9ds0
- st,st_sensors
- st,stm32-dac
- ti,afe4403
- ti,afe4404
- ti,dac7311
* Drop error returns in SPI and I2C remove() functions as they are ignored and
long term plan is to change these all over to returning void. In some cases
these patches just make it 'obvious' they always return 0 where it was the
case before but not easy to tell.
- adi,ad5380
- adi,ad5446
- adi,ad5686
- adi,ad5592r
- bosch,bma400
- bosch,bmc150
- fsl,mma7455
- honeywell,hmc5843
- kionix,kxsd9
- maxim,max5487
- meas,ms5611
- ti,afe4403
Driver specific changes
* adi,ad5770r
- Bring driver inline with documented bindings.
* adi,ad7746
- Trivial style fix
* adi,ad7949
- Express some magic values as the underlying parts via new #defines.
- Make it work with SPI controllers that don't support 14 or 16 bit messages
- Support selection of voltage reference from dt including expanding the
dt-bindings to cover this new functionality.
* adi,ad799x
- Implement selection of external reference voltage on AD7991, AD7995 and
AD7999.
- Add missing dt-bindings doc for devices supported by this driver.
* adi,adislib
- Move interrupt startup to better location in startup flow.
- Handle devices that cannot mask/unmask the drdy pin and must instead mask
at the interrupt controller. Applies to the adis16460 and adis16475 from
which we then drop equivalent code.
* adi,ltc2983
- Add support for optional reset pin.
- Fail to probe if no channels specified in dt binding.
* asahi-kasei,ak8975
- dt-binding additions of missing vid-supply regulator.
* aspeed,aspeed-adc
- Typo fix.
* fsl,mma7660
- Mark acpi_device_id table __maybe_unused to avoid build warning.
* fsl,imx25-gcq
- Avoid initializing regulators that aren't used.
* invensense,mpu3050
- Drop a dead protection against a clash with the old input driver.
* invensense,mpu6050
- Rework code to not use strcpy() and hence avoid possibility of wrong sized
buffers. Note this wasn't a bug, but the new code is a lot more readable.
- Mark acpi_device_id table __maybe_unused to avoid build warning.
* kionix,kxcjk1013
- dt-binding addition to note it supports interrupts.
* marvell,berlin2-adc
- Enable COMPILE_TEST building.
* maxim,max1027
- Avoid returning success in an error path.
* nxp,imx8qxp
- Fix warning when runtime pm not enabled via __maybe_unused.
* ricoh,rn5t618
- Use the new devm_iio_map_array_register() instead of open coding the same.
* samsung,exynos_adc
- Improve kconfig help text.
* st,lsm6dsx
- Move max_fifo_size into the fifo_ops structure where the other configuration
parameters are found.
* st,st_sensors:
- Reorder to ensure we turn the power off after removing userspace interfaces.
* senseair,sunrise
- Add missing I2C dependency.
* ti,twl6030
- Small code tidy up.

TXTAGOCNT and RXTASURECNT bitfields of BTACNTRL1 register are swapped in
the code, correct them. Driver doesn't implement low power mode for now,
so this change doesn't make a practical difference yet.
