CNSS driver controls the power on/off wlan device. because on CPE
platform the link/power status of RC<->USP may be still on when wlan
device is turning on/off, this may cause uncorrectable AER error on
DSP side, to avoid this issue DSP's downstream link should be
disabled before power on/off wlan device, and re-enabled after wlan
power on, and also wait for link training of DSP<->WLAN to complete.
To be compitable with non PCIE switch platform, add a new config
CONFIG_PCIE_SWITCH_SUPPORT to enable/disable this function

The Mbox interface requires structure 'qmp_pkt' which is defined
only when kernel config CONFIG_MSM_QMP is enabled, so add
conditional compilation for these interfaces (controlled by
config CONFIG_MSM_QMP).
While at the same time, qmp_get/qmp_put/qmp_send are controlled
by kernel config CONFIG_QCOM_AOSS_QMP, but they are defined
even when CONFIG_QCOM_AOSS_QMP is disabled, so conditional
compilation is not needed.

Fix misfiring of DEV SOL interrupt during enable_irq().
Ignore DEV SOL interrupt in case of device power off
as it is expected as part of off sequence.
In case of HOST triggered recovery, CNSS driver
tries to put device to RDDM first using MHI_SYS_ERR
and HOST_RESET_REQUEST if MHI_SYS_ERR fails. With
SOL enable, replace HOST_RESET_REQUEST with HOST_SOL.

SW_CTRL_WLAN GPIO so that, when these GPIOs goes high,
PDC get interrupted and TCS sequence(which enables RF_CLK)
can be started.

Converge dt nodes for wlan chips that share the same PCI slot
into one node.
The items in this node are split into 2 parts: common and chip
specific.
The common part will be parsed during cnss probe, such as basic
power related configuration and bus type, to power on the device
and trigger pci probe;
Chip specific part will be parsed during bus specific probe, this
part includes chip specific power and feature related
configurations.
With this change, cnss2 can support different chips on one pci
slot with the same image.

If Device boots up in secure mode, CNSS defers PCI enumeration,
calibration and host driver registration. When secure mode exits
host driver gets notified from CTRL_PARAM and calls PLD API to
perform previously deferred operations and enable WLAN HW. This
can take some seconds and by the time again Secure mode can enter,
disable WLAN and access controlled by TZ.
Now Calibration completes and CNSS receives CAL_DONE indication.
As part of CAL_DONE when CNSS try to power off WLAN access WLAN_EN
it results in NOC error.
One more scenario, where CNSS can access WLAN_EN when WLAN HW
is disabled by TZ, could be when QMI message times out. Consider
secure mode is entering as part of CNSS will to IDLE shutdown.
During IDLE shutdown while sending MODE_OFF QMI message to FW
it might wait for 10 seconds if FW does not respond. But TZ has
timeout of 5 sec if framework does not respond in 5 Sec TZ will
disable WLAN_EN and access control it. Now when after QMI timedout
when try to access WLAN_EN it results in NOC error.
Check secure peripheral state before updating WLAN_EN and maintain
correct driver state in such scenario.

To enable support for qca6390 on hana-au:
1) Return 0, instead of an error code, when 'qcom,icc-path-count'
isn't present in the device tree, given some chipsets like
qca6390 don't need this parameter to get probed successfully;
2) Add one more vreg config, 'vdd-wlan-rfa3', into the vreg list
as it's required for qca6390 to get probed;
3) Add one more dts parameter, 'qcom,multi-wlan-exchg' into the
wlan device tree node on auto platforms, to reflect the fact
that multiple wlan chipsets can be plugged, while only one of
them exists at a time.
Also, reorder the parameters passed for debug printing in function
cnss_plat_ipc_init_fn(), given the original ordering is not
matching with the debug message literally.

The side-band SOL (Sign-Of-Life) GPIOs are introduced to help make
RDDM more reliable so that device dump can be copied correctly. When
device SOL GPIO is triggered from device, it means there is watchdog
reset happened in device and driver should expect RDDM to happen.
When host SOL GPIO is triggered from host, it will result watchdog
reset as well as PCIe controller reset in device which should try to
enter RDDM always. This commit also adds debug hooks for the GPIOs.
