Currently, ath12k does not support BIOS SAR for WCN7850. In order to enable BIOS SAR for WCN7850, ath12k gets BIOS SAR table and GEO offset table in ath12k_acpi_dsm_get_data() function, then sets pdev_id, length of data, and finally sends these data and WMI_PDEV_SET_BIOS_SAR_TABLE_CMDID and WMI_PDEV_SET_BIOS_GEO_TABLE_CMDID to firmware to implement BIOS SAR during the initialization phase. Besides, ath12k registers an ACPI event callback so that ACPI can notify ath12k to get the updated BIOS SAR table and sends it to firmware when the device state is changed.
