+ its prerequisite drivers.

+
+ Tag ath11k-qca6390-bringup-202011301608 from ath tree
+ (https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git) marks
+ first stable milestone on the platform/device under development since
+ v5.6-rc1. Most of the commits under this tag, ~350 commits, have been
+ in vanilla kernel v5.10-rc4 except those starting from commit
+ 065c9528cc50 ("ath11k: add 64bit check before reading msi high addr").
+
+ While ath11k depends on MHI bus, qrtr and qmi helpers, changes falling
+ in these components are also pulled.
+
+ Besides, tx encapsulation
+ https://lore.kernel.org/linux-wireless/[email protected]/
+ and a couple more inclusive of 6 GHz capability, BSS Color were also
+ pulled to satisfy API changes in mac80211/cfg80211.
+
+ [Test Case]
+
+ 1. Install firmwares & boot from patched kernel,
+ 2. ath11k should be now up and running. Check with
+ `sudo dmesg | grep ath11k`
+
+ While this is going to bring massive changes to the kernel, as well as
+ shared wireless stack that is not only used by ath11k but also many
+ others, prebuilt kernel/firmware packages were deployed on platforms
+ with and without ath11k for regression tests, and so far the results are
+ positive.
+
+ [Where problems could occur]
+
+ ath11k and its relying parts have never been enabled in oem-5.6, so
+ changes to them should have little effect on most platforms. For
+ platforms equip QCA6390, this will be the first time they're probed and
+ enabled, and as the driver is still under polishing, there can be
+ regressions, performance lost, power consumption increase at this
+ moment.
+
+ Changes to wireless stack could also be an issue as this introduces
+ interface changes to the API, so maybe DKMS packages in the wild will be
+ affected.

Qualcomm QCA6390 series not recognized due to the lack of ath11k driver.

[Fix]
25 additional fixes in ath tree
(https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git), tag
ath11k-qca6390-bringup-202011301608 to resolve issues on TGL platforms,
and firmware updates from mainline are required.
[Test Case]
1. Install firmwares & boot from patched kernel,
2. ath11k should be now up and running. Check with
`sudo dmesg | grep ath11k`
[Where problems could occur]
There has been a lot patches landed in kernel since 5.7 devel cycle. The
last bits here has merge base with mainline at v5.10-rc4, and since then
only patches for ath11k itself has been committed.
