The t7xx device contains two Cross Layer DMA (CLDMA) interfaces to
communicate with AP and Modem processors respectively. So far only
MD-CLDMA was being used, this patch enables AP-CLDMA and the GNSS
port which requires such channel.
GNSS AT control port allows Modem Manager to control GPS for:
- Start/Stop GNSS sessions,
- Configuration commands to support Assisted GNSS positioning
- Crash & reboot (notifications when resetting device (AP) & host)
- Settings to Enable/Disable GNSS solution
- Geofencing
Change log in v2:
- Add to commit message renaming sAP to AP
- Add to commit message GNSS AT port info
- Lowercase X in constant prefix
- Add GNSS AT comment in static port file

The WD22TB4 Thunderbolt dock at least will revert its DP_MAX_LINK_RATE
from HBR3 to HBR2 after system suspend/resume if the DP_DP13_DPCD_REV
registers are not read subsequently also as required.
Fix this by reading DP_DP13_DPCD_REV registers as well, matching what is
done during connector detection. While at it also fix up the same call
in drm_dp_mst_dump_topology().
In order to not add fancy protection for drv_priv we can move
htc_handle->drv_priv initialization at the end of the
ath9k_htc_probe_device() and add helper macro to make
all *_STAT_* macros NULL safe, since syzbot has reported related NULL
deref in that macros [1]
Due to AP stop improperly, mt7921 driver would face random command timeout
by chip fw problem. Migrate AP start/stop process to .start_ap/.stop_ap and
congiure BSS network settings in both hooks.
The new flow is shown below.
* AP start
.start_ap()
configure BSS network resource
set BSS to connected state
.bss_info_changed()
enable fw beacon offload
* AP stop
.bss_info_changed()
disable fw beacon offload (skip this command)
.stop_ap()
set BSS to disconnected state (beacon offload disabled automatically)
destroy BSS network resource

Additional VMD bridge IDs needed for new Alder Lake platforms, but
actually there is no a complete list for them. Here we match bridge
devices if they're directly attached to a VMD controller instead.

New Intel laptops with VMD cannot reach deeper power saving state,
renders very short battery time.
As BIOS may not be able to program the config space for devices under
VMD domain, ASPM needs to be programmed manually by software. This is
also the case under Windows.
The VMD controller itself is a root complex integrated endpoint that
doesn't have ASPM capability, so we can't propagate the ASPM settings to
devices under it. Hence, simply apply ASPM_STATE_ALL to the links under
VMD domain, unsupported states will be cleared out anyway.
