In order to support multi-link operation with multiple links,
start adding some APIs. The notable addition here is to have
the link ID in a new nl80211 attribute, that will be used to
differentiate the links in many nl80211 operations.
So far, this patch adds the netlink NL80211_ATTR_MLO_LINK_ID
attribute (as well as the NL80211_ATTR_MLO_LINKS attribute)
and plugs it through the system in some places, checking the
validity etc. along with other infrastructure needed for it.
For now, I've decided to include only the over-the-air link
ID in the API. I know we discussed that we eventually need to
have to have other ways of identifying a link, but for local
AP mode and auth/assoc commands as well as set_key etc. we'll
use the OTA ID.
Also included in this patch is some refactoring of the data
structures in struct wireless_dev, splitting for the first
time the data into type dependent pieces, to make reasoning
about these things easier.

The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

For the SDIO driver, the RESET/ENABLE pins of WILC1000 are controlled
through the SDIO power sequence driver. This commit adds analogous
support for the SPI driver. Specifically, during initialization, the
chip will be ENABLEd and taken out of RESET and during
deinitialization, the chip will be placed back into RESET and disabled
(both to reduce power consumption and to ensure the WiFi radio is
off).
Both RESET and ENABLE GPIOs are optional. However, if the ENABLE GPIO
is specified, then the RESET GPIO should normally also be specified as
otherwise there is no way to ensure proper timing of the ENABLE/RESET
sequence.

This follows normal Linux convention and is more useful since the new
name will make it apparent which network device the work-queue is for
(e.g., the name will be "wlan0-wq" for network device "wlan0").
hif_workqueue allocation has to move from
cfg80211.c:wilc_cfg80211_init() to netdev.c:wilc_netdev_ifc_init()
because the network device name is not known until after the netdev is
registered. The move also makes sense because netdev.c is already

When deinitializing the driver, one or more "FW not responding" error
appears on the console. This appears to be due to wilc_wlan_stop()
disabling host/WILC1000 communication, but then right afterwards, it

enabling the chip-sleep cannot success once host/WILC1000

The USE_SPI_DMA macro name suggests that it could be set to 1 to
control whether or not SPI DMA should be used. However, that's not
what it does. If set to 1, it'll set the SPI messages'
"is_dma_mapped" flag to true, even though the tx/rx buffers aren't
actually DMA mapped by the driver. In other words, setting this flag
to 1 will break the driver.
Best to clean up this confusion by removing the macro altogether.
There is no need to explicitly initialize "is_dma_mapped" because the
message is cleared to zero anyhow, so "is_dma_mapped" is set to false
by default.

Increase the WID config packet response timeout to have extra wait time for
host to receive the response message from firmware. Sometimes the WID
config response was timed out because of host interrupt latency.

Instead of using double read for the same register, use the write register
command after the read command.
The correct sequence is to use the read value in write command instead of
reading the same register again.

Add 'initialized' variable check before adding net/mgmt packet to TX queue
as safety check before passing the commands to the firmware.

Add the chip reset command to initialize the WILC chip before downloading
the firmware. Also, put the chip in wake-up mode so it is ready to receive
the firmware binary from the host.

During WILC chip wake-up sequence, the clockless status register sometimes
reports failure even when the actual status is successful. So, for the
clockless register, remove the incorrect error status reporting during the
read and write command API's.

For SPI bus, the register read fails after read/write to the clockless
register during chip wakeup sequence. Add workaround to send CMD_RESET
command during chip wake-up sequence to overcome the issue.

Add reset/terminate/repeat command for SPI module. In case of SPI commands
failure, the host should issue a RESET command to WILC chip to recover
from any temporary bus error.
For now, the new command support is added and later the SPI read/write
API's would be modified to make use of these commands for retry mechanism

Use the correct sequence to configure clockless registers for chip wake-up.
The following sequence is expected from WILC chip for wakeup:
- set wakeup bit in wakeup_reg register
- after setting the wakeup bit, read back the clock status bit for wakeup
complete.
For SDIO/SPI modules, the wakeup sequence is the same except uses different
register values so refactored the code to use common function for both
SDIO/SPI bus.

When the BSS reference holds a valid reference, it is not freed. The 'if'
condition is wrong. Instead of the 'if (bss)' check, the 'if (!bss)' check
is used.
The issue is solved by removing the unnecessary 'if' check because
cfg80211_put_bss() already performs the NULL validation.
Fixes: 6cd4fa5ab691 ("staging: wilc1000: make use of cfg80211_inform_bss_frame()")

locks. After the movement, the client count variable(client_count) which is
