Synchronize the ath11k backports with the current ath-next tree. This backports several memory leak issues, PCI IRQ fixup, peer add locking fix as well as IPQ5018 support, though IPQ5018 support is unused for now. This allows to easily backport further fixes as cherry picking them has started requiring manual conflict resolution. Signed-off-by: Robert Marko <robimarko@gmail.com>

Subject: [PATCH] ath11k: support setting FW memory mode via DT
|
|
|
|
ath11k is really memory intensive for devices with less that 1GB of RAM,
|
|
so lets allow saving a significant amount of memory by setting the FW to
|
|
Mode-1 via DTS for devices that need it.
|
|
|
|
However the drawback is reduced number of VDEV-s and peers which is a
|
|
reasonable tradeoff.
|
|
|
|
Mode-2 allows for further reduction, but it has further restrictions.
|
|
|
|
While we are here, lets add a print to be able to easily determine what
|
|
FW memory mode is being used.
