2.34.1
Currently, ath12k does not have the ability to set band edge channel power
for WCN7850. In order to support this, ath12k gets band edge channel power
table in ath12k_acpi_dsm_get_data() function and sets pdev_id and
param_type_id, then finally sends these data and
WMI_PDEV_SET_BIOS_INTERFACE_CMDID to firmware to set band edge channel
power.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4

Currently, ath12k does not have the ability to adjust CCA threshold values
to meet the regulatory requirements. In order to support this, ath12k gets
CCA threshold configuration in ath12k_acpi_dsm_get_data() function, then
sets pdev_id and param_type_id and finally sends these data to firmware to
implement the adjustment of the CCA threshold value.
