In ACPI SAR enabled device, mt7921 should read power limit in ACPI config. The limit value would be applied to regular tx power settings in mt76. Two major functionalities added: 1. Get SAR power table through ACPI. 2. Read power in Dynamic/Geo SAR table for tx power limit. Table note MTDS: Dynamic SAR table MTGS: Geo SAR table MTCL: Country List table (for 6GHz support) Reviewed-by: Sean Wang <[email protected]> Co-developed-by: Quan Zhou <[email protected]> Signed-off-by: Quan Zhou <[email protected]> Co-developed-by: Ming Yen Hsieh <[email protected]> Signed-off-by: Ming Yen Hsieh <[email protected]> Signed-off-by: Deren Wu <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>
