We can simplify the runtime resume ELP path by always setting and
clearing the completion in runtime resume. This way we can test for
WL1271_FLAG_IRQ_RUNNING after the resume write to see if we need
completion at all.
And in wlcore_irq(), we need to take spinlock for running the
completion and for the pm_wakeup_event(). Spinlock is not needed
around the bitops flags check for WL1271_FLAG_SUSPENDED so the
spinlocked sections get shorter.

Some platforms cannot read the DBI register successfully for the
ASPM settings. After the read failed, the bus could be unstable,
and the device just became unavailable [1]. For those platforms,
the ASPM should be disabled. But as the ASPM can help the driver
to save the power consumption in power save mode, the ASPM is still
needed. So, add a module parameter for them to disable it, then
the device can still work, while others can benefit from the less
power consumption that brings by ASPM enabled.

The TX power requires to be adjusted based on the thermal value.
The actual power will decrease if the thermal value raised, and
will increase if the thermal value lowered. Driver comapres the
thermal value, as moving averages. If it changes over a limit,
driver will modify the TX power index to compensate.

The code in the BRCM80211 BRCMSMAC driver is using the legacy
GPIO API to to a complex check of the validity of the base of
the GPIO chip and whether it is present at all and then adding
an offset to the base of the chip.
Use the existing function to obtain a GPIO line internally
from a GPIO chip so we can use the offset directly and
modernize the code to use GPIO descriptors instead of integers
from the global GPIO numberspace.

The driver relies on the compatible string from DT to determine which
FW configuration file it should load. The DTS spec allows for '/' as
part of the compatible string. We change this to '-' so that we will
still be able to load the config file, even when the compatible has a
'/'. This fixes explicitly the firmware loading for
"solidrun,cubox-i/q".

When USB or SDIO device got abnormal bus disconnection, host driver
tried to clean up the skbs in PSQ and TXQ (The skb's pointer in hanger
slot linked to PSQ and TSQ), so we should set the state of skb hanger slot
to BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing skb.
In brcmf_fws_bus_txq_cleanup it already sets
BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing skb, therefore we add the
same thing in brcmf_fws_psq_flush to avoid following warning message.

It is observed that sometimes when sdiod is low in tx credits in low
rssi scenarios, the data path consumes all sdiod rx all credits and
there is no sdiod rx credit available for control path causing host
and card to go out of sync resulting in link loss between host and
card. So in order to prevent it some credits are reserved for control
path.
Note that TXCTL_CREDITS can't be larger than the firmware default
credit update threshold 2; otherwise there will be a deadlock for both
side waiting for each other.

The firmware state machines are not fully suitable for concurrent
station interface support, it may hit unexpected error if we have 2
different SSIDs and the roaming scenarios concurrently.
To avoid the bad user-experience if this is not fully validated, we
dis-allow user to create two concurrent station interfaces.

brcmfmac host driver makes SDIO bus sleep and stops SDIO watchdog if no
pending event or data. As a result, host driver does not poll firmware
console buffer before buffer overflow, which leads to missing firmware
logs. We should not stop SDIO watchdog if console_interval is non-zero
in debug build.

When host driver retrieves mac addresses from dongle, driver copies memory
from drvr->mac to perm_addr. But at the moment, drvr->mac is all zero
array which causes permanent MAC address in wiphy is all zero as well.
To fix this, we set drvr->mac before setting perm_addr.

To truncate the additional bytes, if extra bytes have been received.
Current code only have a warning and proceed without handling it.
But in one of the crash reported by DVT, these causes the
crash intermittently. So the processing is limit to the skb->len.

Some thermal zone devices never change their state, so they should be

Organize driver documentation by device type. Most documents
have fairly verbose yet uninformative names, so let users
first select a well defined device type, and then search for
a particular driver.
While at it rename the section from Vendor drivers to
Hardware drivers. This seems more accurate, besides people
sometimes refer to out-of-tree drivers as vendor drivers.

WILC1000 is an IEEE 802.11 b/g/n IoT link controller module. The
WILC1000 connects to Microchip AVR/SMART MCUs, SMART MPUs, and other
processors with minimal resource requirements with a simple
SPI/SDIO-to-Wi-Fi interface.
WILC1000 driver has been part of staging for few years. With
contributions from the community, it has improved significantly. Full
driver review has helped in achieving the current state.
The details for those reviews are captured in 1 & 2.

The napi_gro_receive function no longer returns GRO_DROP ever, making
handling GRO_DROP dead code. This commit removes that dead code.
Further, it's not even clear that device drivers have any business in
taking action after passing off received packets; that's arguably out of
their hands. In this case, too, the non-gro path didn't bother checking
the return value. Plus, this had some clunky debugging functions that
duplicated code from elsewhere and was generally pretty messy. So, this
commit cleans that all up too.
