Subject: [PATCH 2/6] wifi: ath11k: add hw params for QCN6122
From: George Moussalem <george.moussalem@...look.com>
Add QCN6122 platform support.
QCN6122 is a PCIe based solution that is attached to and enumerated
by the WPSS (Wireless Processor SubSystem) Q6 processor.
Though it is a PCIe device, since it is not attached to APSS processor
(Application Processor SubSystem), APSS will be unaware of such a decice
so it is registered to the APSS processor as a platform device (AHB).
Because of this hybrid nature, it is called as a hybrid bus device.
QCN6122 is similar to WCN6750 and follows the same codepath as for
WCN6750 though it does not support shadow regs.
