One PCIe function per network port (more precisely, per m-port group) is
responsible for configuring the Match-Action Engine which performs
switching and packet modification in the slice to support flower/OVS
offload. The GRP_MAE bit in the privilege mask indicates whether a
given function has this capability.
At probe time, call MCDIs to read the calling function's privilege mask,
and store the GRP_MAE bit in a new ef100_nic_data member.

The open code which is netif_is_bridge_port() || netif_is_ovs_port() is
defined as a new helper function on netdev.h like netif_is_any_bridge_port
that can check both IFF flags in 1 go. So use netif_is_any_bridge_port()
function instead of open code. This patch doesn't change logic.

The remove callback is only called after probe completed successfully.
In this case platform_set_drvdata() was called with a non-NULL argument
and so ecc_dev is never NULL.
This is a preparation for making platform remove callbacks return void.

init_cpu_topology() is called only once at the boot and all the cache
attributes are detected early for all the possible CPUs. However when
the CPUs are hotplugged out, the cacheinfo gets removed. While the
attributes are added back when the CPUs are hotplugged back in as part
of CPU hotplug state machine, it ends up called quite late after the
update_siblings_masks() are called in the secondary_start_kernel()
resulting in wrong llc_sibling_masks.
Move the call to detect_cache_attributes() inside update_siblings_masks()
to ensure the cacheinfo is updated before the LLC sibling masks are
updated. This will fix the incorrect LLC sibling masks generated when
the CPUs are hotplugged out and hotplugged back in again.

Currently, everytime an information needs to be fetched from the PPTT,
the table is mapped via acpi_get_table() and unmapped after the use via
acpi_put_table() which is fine. However we do this at runtime especially
when the CPU is hotplugged out and plugged in back since we re-populate
the cache topology and other information.
However, with the support to fetch LLC information from the PPTT in the
cpuhotplug path which is executed in the atomic context, it is preferred
to avoid mapping and unmapping of the PPTT for every single use as the
acpi_get_table() might sleep waiting for a mutex.
In order to avoid the same, the table is needs to just mapped once on
the boot CPU and is never unmapped allowing it to be used at runtime
with out the hassle of mapping and unmapping the table.

Hi Rafael,
Sorry to bother you again on this PPTT changes. Guenter reported an issue
with lockdep enabled in -next that include my cacheinfo/arch_topology changes
to utilise LLC from PPTT in the CPU hotplug path.
Please ack the change once you are happy so that I can get it merged with

On couple of architectures like RISC-V and ARM64, we need to detect
cache attribues quite early during the boot when the secondary CPUs
start. So we will call detect_cache_attributes in the atomic context
and since use of normal allocation can sleep, we will end up getting
"sleeping in the atomic context" bug splat.
In order avoid that, move the allocation to use atomic version in
preparation to move the actual detection of cache attributes in the
CPU hotplug path which is atomic.

2nd set of IIO new device support, cleanup etc for 5.20
Given the slight delay in the likely start of the merge cycle lets get
a few more things in for IIO. A few late breaking fixes also included.
Bulk in number of patches is mechanical conversion to new PM macros.
New device support
* npcm
- Add support for NPCM8XX with different resolution and voltage references
from previously supported parts.
Tree wide
* pm_ptr()/pm_sleep_ptr()/DEFINE_[SIMPLE/RUNTIME]_DEV_PM_OPS() conversions
- Convert all the low hanging fruit to the new macros. The remaining
cases will need more careful consideration.
Tidy-up, fixes and minor features.
* Documentation
- Fix duplicate ABI definitions and a missing blank line to squash all
remaining docs build issues in IIO.
* core
- Make iio_format_avail_range() handle non IIO_VAL_INT cases.
* core/trigger
- Move the setup of trigger->owner to allocation rather than registration.
There doesn't seem to be any advantage in doing this late and a few bugs
have occurred because of mis-balanced module reference counting.
- coding style fix-ups.
* tests
- Allow kunit tests to be built as a module.
* ad7949
- Fix a reversed error message.
* cio-dac
- Use structures for register map to improve readability.
* cros_ec
- Register fifo callback only after the sensor is registered. Closes
a theoretical race.
* hmc5843
- Duplicate word fix.
* isl29028
- Fix mixed devm_ and non devm_ for iio_device_register().
* max1027
- Fix missing unlocks in error paths.
* rm3100
- Let core code handle setting INDIO_BUFFER_TRIGGERED.
* sca3000
- Fix ordering and buffer size issue.
* sx_common
- Don't use the IIO device to get device properties when the parent struct
device is readily available.
- Allow the IIO core to connect up the firmware node.
* stx104
- Use structures for register map to improve readability.
* vf610-adc
- Add compatible entries for imx6ul and imx6sx with fallback to
fsl,vf610-adc.

While phylink_pcs_ops :: pcs_get_state does return void, xpcs_get_state()
does check for a non-zero return code from xpcs_get_state_c37_sgmii()
and prints that as a message to the kernel log.
However, a non-zero return code from xpcs_read() is translated into
"return false" (i.e. zero as int) and the I/O error is therefore not
printed. Fix that.

Add device specific data for max baudrate in autobaud mode. This allows the
host to use a baudrate higher than "init speed" when loading FW in autobaud
mode.
The device specific max baudrate in autobaud mode for CYW55572 is set to
921600 bps. Devices without device specific max baudrate in autobaud mode
will use init speed as before. If no device specific init speed has been
specified, it will default to the bcm_proto default 115200 bps.
The increased baud rate improves FW load time. The exact load time will
depend on the specific system and FW being used. As a rough indication,
the FW load time dropped from ~9s @ 115.2kbps to ~1.7s @ 921.6kbps in one
test.

Bluetooth HCI devices indicate if they are able to wakeup in the wakeup
callback since 'commit 4539ca67fe8e ("Bluetooth: Rename driver
.prevent_wake to .wakeup")'. This patch adds a default wakeup callback
for Bluetooth HCI UAR devices. It assumes Bluetooth HCI UART devices are
wakeable for backward compatibility. For those who need a customized
behavior, one can override it before calling hci_uart_register_device().

Commit ce64b3e94919 ("Bluetooth: mt7921s: Support wake on bluetooth")
adds the wake on bluethooth via a dedicated GPIO.
Extend the wake-on-bluetooth to use the SDIO DAT1 pin (in-band wakeup),
when supported by the SDIO host driver.

The BCM4349B1, aka CYW/BCM89359, is a WiFi+BT chip and its Bluetooth
portion can be controlled over serial.
Two subversions are added for the chip, because ROM firmware reports
002.002.013 (at least for the chips I have here), while depending on
patchram firmware revision, either 002.002.013 or 002.002.014 is
reported.

Use the presence of a DT property, "brcm,requires-autobaud-mode", to enable
startup in autobaud mode. If the property is present, the device is started
in autobaud mode by asserting RTS (BT_UART_CTS_N) prior to powering on the
device.
Also prevent the use of unsupported commands for devices started in
autobaud mode. Only a limited subset of HCI commands are supported in
autobaud mode.
Some devices (e.g. CYW5557x) require autobaud mode to enable FW loading.
Autobaud mode can also be required on some boards where the controller
device is using a non-standard baud rate in normal mode when first powered
on.

Defer allocating the gendisk and request_queue until UBLK_CMD_START_DEV
is called. This avoids funky life times where a disk is allocated
and then can be added and removed multiple times, which has never been
supported by the block layer.

Looking at the hctxs and cpumap is not safe without at very last a RCU
reference. It also requires the queue to be set up before starting the
device, which leads to rather awkward life time rules.
Instead rewrite ublk_ctrl_get_queue_affinity to just build the cpumask
directly from the mq_map in the tag set, similar to hctx->cpumask is
built.

Move all per-command work into the per-command ublk_ctrl_* helpers
instead of being split over those, ublk_ctrl_cmd_validate, and the main
ublk_ctrl_uring_cmd handler. To facilitate that, the old
ublk_ctrl_stop_dev function that just contained two function calls is
folded into both callers.

fops->open and fops->release are always paired. Use simple atomic bit
ops ot indicate if the device is opened instead of a count that can
only be 0 and 1 and a useless cmpxchg loop in ublk_ch_release.
Also don't bother clearing file->private_data is the file is about to
be freed anyway.
