The new TLV format enables adding TLVs after the fixed
fields in radiotap, as part of the radiotap header.
Support this and move vendor data to the TLV format,
allowing a reuse of the RX_FLAG_RADIOTAP_VENDOR_DATA as
the new RX_FLAG_RADIOTAP_TLV_AT_END flag.

Customers using GKE 1.25 and 1.26 are facing conntrack issues
root caused to commit c9c3b6811f ("netfilter: conntrack: make
max chain length random").
Even if we assume Uniform Hashing, a bucket often reachs 8 chained
items while the load factor of the hash table is smaller than 0.5
With a limit of 16, we reach load factors of 3.
With a limit of 32, we reach load factors of 11.
With a limit of 40, we reach load factors of 15.
With a limit of 50, we reach load factors of 24.
This patch changes MIN_CHAINLEN to 50, to minimize risks.
Ideally, we could in the future add a cushion based on expected
load factor (2 * nf_conntrack_max / nf_conntrack_buckets),
because some setups might expect unusual values.

The check that beacon primary channel is in the range of 80 MHz
(abs < 80) is invalid for 320 MHz since duplicate beacon transmit
means that the AP transmits it on all the 20 MHz sub-channels:
9.4.2.249 HE Operation element - ... AP transmits Beacon frames in
non-HT duplicate PPDU with a TXVECTOR parameter CH_BANDWIDTH value
that is up to the BSS bandwidth.
So in case of 320 MHz the DUP beacon can be in upper 160 for primary
channel in the lower 160 giving possibly an absolute range of over
80 MHz.
Also this check is redundant alltogether, if AP has a wrong primary
channel in the beacon it's a faulty AP, and we would fail in next
steps to connect.
While at it, fix the frequency comparison to no longer compare
between KHz and MHz, which was introduced by commit 7f599aeccb
("cfg80211: Use the HE operation IE to determine a 6GHz BSS channel").

Currently in case DUP bit is not set we don't return the primary
channel for 6 GHz Band, but the spec says that the DUP bit has
no effect on this field:
9.4.2.249 HE Operation element:
The Duplicate Beacon subfield is set to 1 if the AP transmits
Beacon frames in non-HT duplicate PPDU with a TXVECTOR parameter
CH_BANDWIDTH value that is up to the BSS bandwidth and is set to
0 otherwise.
So remove the condition for returning primary channel based on DUP.
Since the caller code already marks the signal as invalid in case
the indicated frequency is not the tuned frequency, there's no need
to additionally handle this case here since that's already true for
duplicated beacons on the non-primary channel(s).

Add support for both the BananaPi BPI-CM4 module and the BananaPi
baseboard which is compatible with the RaspberryPi CM4IO baseboard.
The BananaPi BPI-CM4 module follows the CM4 specifications at [1],
but with a single HDMI port and a single DSI output.
The current CM4IO baseboard DT should work fine on the Raspberry CM4
baseboard and other derivatives baseboards, but proper DT should
be written for other baseboards.
The split is done so it's easy to describe a new CM4 baseboard, enabling
only the necessary HW used on the baseboard.

So the far, GXL SoCs were using the generic mmio register based mdio
multiplexer. This properly sets one of the glue register but the SoC
actually has 3 of those registers.
One of them sets the ID under which the internal phy will advertise
itself. If nothing sets this register before linux boots (like u-boot), the
internal phy path is broken.
To address this problem, a dedicated MDIO mux driver has been
introduced. Switch to this new driver.

The previous patch added the device tree to support Toradex Apalis
iMX8 [1] aka QuadMax a computer on module which can be used on
different carrier boards which this patch introduces.
The module consists of an NXP i.MX 8 family SoC (either i.MX 8QuadMax or
8QuadPlus), two PF8100 PMICs, a KSZ9131 Gigabit Ethernet PHY, 2, 4 or 8
GB of LPDDR4 RAM, an eMMC, an SGTL5000 analogue audio codec, an USB3503A
USB HSIC hub, an optional I2C EEPROM plus an optional Bluetooth/Wi-Fi
module.
Anything that is not self-contained on the module is disabled by
default.
The carrier board device trees contained in this patch include the
module's device tree and enable the supported peripherals of the
carrier board.
Some level of display functionality just landed upstream but requires
further integration/testing on our side. Therefore, currently only
basic console UART, eMMC and Ethernet functionality work fine.
As there is no i.MX 8QuadPlus device tree upstream those have been
dropped. However, apart from an error message during boot about it
failing to bring up the second Cortex-A72 core this boots fine on
QuadPlus' as well.

This patch adds the device tree to support Toradex Apalis iMX8 [1] aka
QuadMax a computer on module which can be used on different carrier
boards.
The module consists of an NXP i.MX 8 family SoC (either i.MX 8QuadMax or
8QuadPlus), two PF8100 PMICs, a KSZ9131 Gigabit Ethernet PHY, 2, 4 or 8
GB of LPDDR4 RAM, an eMMC, an SGTL5000 analogue audio codec, an USB3503A
USB HSIC hub, an optional I2C EEPROM plus an optional Bluetooth/Wi-Fi
module.
Anything that is not self-contained on the module is disabled by
default.
The carrier board device trees in the next patch will include the
module's device tree and enable the supported peripherals of the
carrier board.
Some level of display functionality just landed upstream but requires
further integration/testing on our side. Therefore, currently only
basic console UART, eMMC and Ethernet functionality work fine.
As there is no i.MX 8QuadPlus device tree upstream those have been
dropped. However, apart from an error message during boot about it
failing to bring up the second Cortex-A72 core this boots fine on
QuadPlus' as well.

Add CAN node for imx8qm in devicetree.
Unlike on the i.MX 8QXP where the flexcan clocks are shared between
multiple CAN instances, the i.MX 8QM has separate flexcan clock slices.

60MHz is the maximum frequency mentioned in the datasheet for
master mode. Set that to 60MHz to match lpspi2.

This commit adds io-channel-cells property to the ADC nodes. This
property is required in order for an IIO consumer driver to work.
Especially required for Apalis iMX8 QM, as the touchscreen driver
uses ADC channels with the ADC driver based on IIO framework.

Add toradex,apalis-imx8 for the Apalis iMX8 aka QuadMax modules and the
carrier boards (Apalis Evaluation board as well as Ixora V1.1 and V1.2)
they may be mated in.
