Subject: [PATCH v2 07/19] ath11k: Add bus params for WCN6750
Date: Sun, 16 Jan 2022 18:17:03 +0530	[thread overview]
Message-ID: <1642337235-8618-8-git-send-email-quic_mpubbise@quicinc.com> (raw)
In-Reply-To: <1642337235-8618-1-git-send-email-quic_mpubbise@quicinc.com>

WCN6750 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
and hence 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.

A new variable is defined in bus params to indicate the hybrid nature.
Add bus params for WCN6750.

Tested-on: WCN6750 hw1.0 AHB WLAN.MSL.1.0.1-00573-QCAMSLSWPLZ-1
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.5.0.1-01100-QCAHKSWPL_SILICONZ-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-00192-QCAHKSWPL_SILICONZ-1
