bh_work() is in charge to schedule all HIF message from/to chip.
On normal operation, when an IRQ is received, driver can get size of
next message in control register. In order to save control register
access, when chip send a message, it also appends a copy of control
register after the message (this register is not accounted in message
length declared in message header, but must accounted in bus request).
This copy of control register is called "piggyback".
It also handles a power saving mechanism specific to WFxxx series. This
mechanism is based on a GPIO called "wakeup" GPIO. Obviously, this gpio
is not part of SPI/SDIO standard buses and must be declared
independently (this is the main reason for why SDIO mode try to get
parameters from DT).
When wakeup is enabled, host can communicate with chip only if it is
awake. To wake up chip, there are two cases:
- host receive an IRQ from chip (chip initiate communication): host
just have to set wakeup GPIO before reading data
- host want to send data to chip: host set wakeup GPIO, then wait
for an IRQ (in fact, wait for an empty message) and finally send data
bh_work() is also in charge to track usage of chip buffers. Normally
each request expect a confirmation. However, you can notice that special
"multi tx" confirmation can acknowledge multiple requests at time.
Finally, note that wfx_bh_request_rx() is not atomic (because of
control_reg_read()). So, in SPI mode, hard-irq handler only postpone all
processing to wfx_spi_request_rx().

These files are shared with firmware sources. Only a subset of these
definitions are used by driver but, for now, it is easier to import all.
API defines 3 kinds of messages:
- Requests (req) are sent from host to chip
- Confirmations (cnf) are sent by chip and are always in reply to a
request
- Indications (ind) are spontaneous message from chip to host
One request normally generate one confirmation. There are a few
exceptions to this rule:
- "shutdown" request is not acknowledged
- multiple tx request can be acknowledged a unique "multi-tx"
confirmation
In add, API defines MIB. They are sub-structures for write_mib and
read_mib API.
Note that all numbers in API have to be little endian when sent/received
from/to chip (I didn't declared them with __le32 because driver also use
them internally).

A firmware is necessary to run the chip. wfx_init_device() is in charge
of loading firmware on chip and doing low level initialization.
Firmwares for WF200 are available here:
https://github.com/SiliconLabs/wfx-firmware/
Note that firmware are encrypted. Driver checks that key used to encrypt
firmware match with key burned into chip.
Currently, "C0" key is used for production chips.

Instantiate build infrastructure WFx driver. This driver provides support
for Wifi chipset Silicon Labs WF200 and further:
https://www.silabs.com/documents/public/data-sheets/wf200-datasheet.pdf
This chip support SPI and SDIO bus.
SDIO interface has two particularities:
1. Some parameters may be useful for end user (I will talk about
gpio_wakeup later).
2. The SDIO VID and PID of WF200 are 0000:0001 which are too much
generic to rely on.
So, current code checks VID/PID and looks for a node in DT (since WF200
targets embedded platforms, I don't think it is a problem to rely on
DT). DT can also be used to define to parameters for driver. Currently,
if no node is found, a warning is emitted, but it could be changed in
error.

The majority of them were totally backwards. Change the logic
so that if DELAYED_SYNC *isn't* in the config, we actually flush to disk
before flagging the file system as clean.
That leaves two calls in the DELAYED_SYNC case. More detailed
analysis is needed to make sure that's what's really needed, or if other
call sites also need a fs_sync() call. This patch is at least "less wrong"
than the code was, but further changes should be another patch.

The update operation on 'vif' list is less compare to the read

The local variable 'bcmd_down' is always set to true almost immediately
before the do-while's condition is checked. As a result, !bcmd_down
evaluates to false which short circuits the logical AND operator meaning
that the second operand is never reached and is therefore dead code.
Furthermore, the do..while loop may be removed since it will always only
execute once because 'bcmd_down' is always set to true, so the
!bcmd_down evaluates to false and the loop exits immediately after the
first pass.
Fix this by removing the loop and its condition variables 'bcmd_down'
and 'retry_cnts'

Here is the big set of USB patches for 5.4-rc1.
Two major chunks of code are moving out of the tree and into the staging
directory, uwb and wusb (wireless USB support), because there are no
devices that actually use this protocol anymore, and what we have today
probably doesn't work at all given that the maintainers left many many
years ago. So move it to staging where it will be removed in a few
releases if no one screams.
Other than that, lots of little things. The usual gadget and xhci and
usb serial driver updates, along with a bunch of sysfs file cleanups due
to the driver core changes to support that. Nothing really major, just
constant forward progress.
All of these have been in linux-next for a while with no reported
issues.

Merge tag 'usb-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB updates from Greg KH:
"Here is the big set of USB patches for 5.4-rc1.
Two major chunks of code are moving out of the tree and into the
staging directory, uwb and wusb (wireless USB support), because there
are no devices that actually use this protocol anymore, and what we
have today probably doesn't work at all given that the maintainers
left many many years ago. So move it to staging where it will be
removed in a few releases if no one screams.

due to the driver core changes to support that. Nothing really major,
