Subject: [PATCH v6 1/4] wifi: ath12k: add TAS capability for WCN7850
Date:   Wed, 11 Oct 2023 01:00:01 -0400
Message-ID: <20231011050004.423413-2-quic_lingbok@quicinc.com>
In-Reply-To: <20231011050004.423413-1-quic_lingbok@quicinc.com>

Currently, ath12k does not support Time-Average-SAR(TAS) for WCN7850. In
order to enable Time-Average-SAR(TAS) for WCN7850, ath12k defines
ath12k_get_acpi_all_data() function to get TAS configuration and SAR power
table, then sets pdev_id, param_type_id, and finally sends the TAS
configuration, SAR power table and WMI_PDEV_SET_BIOS_INTERFACE_CMDID
command to firmware to implement TAS during the initialization phase.
Besides, ath12k registers an ACPI event callback so that ACPI can notify
ath12k to get the updated SAR power table and sends it to firmware when the
device state is changed.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
