531 * ath9k_hw_decrease_chain_power()
532 *
533 * @ah: atheros hardware structure
534 * @chan:
535 *
536 * Only used on the AR5416 and AR5418 with the external AR2133/AR5133 radios.
537 *
538 * Sets a chain internal RF path to the lowest output power. Any
539 * further writes to bank6 after this setting will override these
540 * changes. Thus this function must be the last function in the
541 * sequence to modify bank 6.
542 *
543 * This function must be called after ar5416SetRfRegs() which is
544 * called from ath9k_hw_process_ini() due to swizzling of bank 6.
545 * Depends on ah->analogBank6Data being initialized by
546 * ath9k_hw_set_rf_regs()
547 *
548 * Additional additive reduction in power -
549 * change chain's switch table so chain's tx state is actually the rx
550 * state value. May produce different results in 2GHz/5GHz as well as
551 * board to board but in general should be a reduction.
552 *
553 * Activated by #ifdef ALTER_SWITCH. Not tried yet. If so, must be
554 * called after ah->eep_ops->set_board_values() due to RMW of
555 * PHY_SWITCH_CHAIN_0.
