    iwlwifi: mvm: add GEO_TX_POWER_LIMIT cmd for geographic tx power table · a6bff3cb
    Haim Dreyfuss authored
    To utilize the maximum allowed tx power, an additional table was added
    to the BIOS. The table consists of up to seven different regions
    (currently only three are in use). Each region contains per band:
    1. Maximum allowed tx power on the band.
    2. Tx power offset for chain A.
    3. Tx power offset for chain B.
    On init flow driver reads this table by means of ACPI and
    passes it to the firmware with GEO_TX_POWER_LIMIT cmd.
    The firmware will use this table to enhance tx power with
    the offset in the relevant table as well as verifying it does not
    violate the maximum allowed tx power.
