64866e5da1 iwlwifi: move iwl_nvm_check_version() into dvm
This function is only half-used by mvm (i.e. only the nvm_version part
matters, since the calibration version is irrelevant), so it's
pointless to export it from iwlwifi.  If mvm uses this function, it
has the additional complexity of setting the calib version to a bogus
value on all cfg structs.

To avoid this, move the function to dvm and make a simple comparison
of the nvm_version in mvm instead.

the data and set it into our internal table.  We use the number of
profiles specified in ACPI without checking its validity, so if the
ACPI table is corrupted and the number is larger than our array size,
we will try to make an out-of-bounds access.

Fix this by making sure the value specified in the ACPI table is

Some devices use a shared clock which is very sensitive to variations

extra_phy_config_flags element to the device configuration and OR it
into the phy_cfg before sending it to the firmware.  And also create a
set of configurations for devices that use shared clocks and need this
extra bit to be set.

which everything continues as usual, only without
stopping the device after INIT, even if there is no FW
assert. On 22000 HW, for instance, this causes a

813df5cef3 iwlwifi: acpi: add common code to read from ACPI
There are many places where the same process of invoking a method from
ACPI is used, causing a lot of duplicate code.  To improve this,
introduce a new function to get an ACPI object by invoking an ACPI
method that can be reused.

Additionally, since this function needs to be called when we only have
the trans, the opmode or the device, introduce a new debug macro that
gets the device as a parameter so it can be used in the new function.

Stephen Rothwell reported quite a few conflicts in iwlwifi between
wireless-drivers and wireless-drivers-next. To avoid any problems later in
other trees merge w-d to w-d-next to fix those conflicts early.

5bd1d2c1ea iwlwifi: mvm: remove useless argument in iwl_nvm_init()
We always call iwl_nvm_init() with read_nvm_from_nic == true, so this
argument is useless.  Remove it.

We have some of the SAR dummy functions when ACPI is not set declared
in mvm.h and some declared in fw.c.  Group them all together in fw.c
for consistency and to avoid static/non-static issues.

00e0c6c8fe iwlwifi: mvm: consider RFKILL during INIT as success
There's no need to differentiate an INIT that ended early because of
RFKILL from one that succeded.  Additionally, if INIT fails later,
during calibration, due to RFKILL, we can just return success and
continue as if we were already in RFKILL to start with.

Remove this unnecessary differentiation and do some other small
clean-ups while at it.

7089ae634c iwlwifi: mvm: use firmware LED command where applicable
On devices starting from 8000 series, the host can no longer toggle
the LED through the CSR_LED_REG register, but must do it via the
firmware instead. Add support for this. Note that this means that
the LED cannot be turned on while the firmware is off, so using an
arbitrary LED trigger may not work as expected.

The first wireless-drivers-next pull request for 4.14. I'm submitting
 this unusally late in the cycle as my vacation postponed this. But
 even if this is late there's not still that much new features, mostly
 cleanup or fixes.
 
 Major changes:

 * preparation for wcn3990 support
 
 iwlwifi
 
 * Reorganization of the code into separate directories continues
 
 qtnfmac
 
 * regulatory support updates
 
 * add get_channel, dump_survey and channel_switch cfg80211 handlers

c8c017a6ff iwlwifi: mvm: check family instead of new TX API for workarounds
There are two workarounds because RSS is currently broken on A000
devices due to firmware issues, but checking for the new TX API
doesn't really make sense. Check the hardware family instead of
the new TX API - there's nothing better to check since it's just
a temporary workaround.
