With the current implementation of wmi init command,
there is no provision for the host driver to provide mem
chunks addresses with more than 32-bit, to the firmware.
WCN3990 is a 35-bit target and can accept mem chunks addresses
which are above 32-bit.
If firmware supports address range more than 32 bit, it
advertises the support by setting the WMI_SERVICE_EXTEND_ADDRESS
service. Based on this service fill the upper bits of paddr while
providing the mem chunks in the wmi init command.

PMIC XO is the clock source for wifi rf clock in integrated wifi
chipset ex: WCN3990. Due to board layout errors XO frequency drifts
can cause wifi rf clock inaccuracy.
XO calibration test tree in Factory Test Mode is used to find the
best frequency offset(for example +/-2KHz )by programming XO trim
register. This ensure system clock stays within required 20 ppm
WLAN rf clock.
Retrieve the xo trim offset via system firmware (e.g., device tree),
especially in the case where the device doesn't have a useful EEPROM
on which to store the calibrated XO offset (e.g., for integrated Wifi).
Calibrated XO offset is sent to fw, which compensate the clock drift
by programing the XO trim register.

The regulator_get_optional() exists for cases where the driver needs do
behave differently depending on some regulator supply being present or
not, as we don't use this we can use the standard regulator_get() and
rely on its handling of unspecified regulators.
While the driver currently doesn't specify any loads the regulator
framework was updated last year to only account for load of enabled
regulators, so should the need appear it's better to apply load numbers
during initialization that dynamically.
With this the regulator wrappers have been reduced the become identical

The introduction of 768ec4c012 ("ath10k: update HOST capability QMI
message") served the purpose of supporting the new and extended HOST
capability QMI message.
But while the new message adds a slew of optional members it changes the
data type of the "daemon_support" member, which means that older
versions of the firmware will fail to decode the incoming request
message.
There is no way to detect this breakage from Linux and there's no way to
recover from sending the wrong message (i.e. we can't just try one
format and then fallback to the other), so a quirk is introduced in
DeviceTree to indicate to the driver that the firmware requires the 8bit
version of this message.

A Mediatek based smartphone owner reports problems with USB
tethering in Linux. The verbose USB listing shows a rndis_host
interface pair (e0/01/03 + 10/00/00), but the driver fails to
bind with
[ 355.960428] usb 1-4: bad CDC descriptors
The problem is a failsafe test intended to filter out ACM serial
functions using the same 02/02/ff class/subclass/protocol as RNDIS.
The serial functions are recognized by their non-zero bmCapabilities.
No RNDIS function with non-zero bmCapabilities were known at the time
this failsafe was added. But it turns out that some Wireless class
RNDIS functions are using the bmCapabilities field. These functions
are uniquely identified as RNDIS by their class/subclass/protocol, so
the failing test can safely be disabled. The same applies to the two
types of Misc class RNDIS functions.
Applying the failsafe to Communication class functions only retains
the original functionality, and fixes the problem for the Mediatek based
smartphone.
Tow examples of CDC functional descriptors with non-zero bmCapabilities
from Wireless class RNDIS functions are:
0e8d:000a Mediatek Crosscall Spider X5 3G Phone
CDC Header:
bcdCDC 1.10
CDC ACM:

Power amplifiers are not linear components, and require DPK to
reduce its nonlinearity. DPK is called Digital Pre-distortion
Calibration, can be used to compensate the output of power.
DPK tracking is in charge of tracking the thermal changes. And
it then shifts the power curve accordingly, which makes the
power output remains linear even if the PA works in different
temperature.
To perform DPK, the parameter table should also be updated.
And the table will be applied when device is powered on.
Then DPK will reference the values to calibrate.

Add support for doing IQK in firmware
Ideally the RF component's I/Q vectors should be orthogonal,
but usually they are not. So we need to calibrate for the RF
components, ex. PA/LNA, ADC/DAC.
And if the I/Q vectors are more orthogonal, the mixed signal
will have less deviation. This helps with those rates with
higher modulation (MCS8-9), because they have more strict
EVM/SNR requirement. Also the better of the quality of the
signal, the longer it can propagate, and the better throughput
performance we can get.

As a first step in the conversion, the macros that set the RX and TX

That will be changed in the next patch.
