24 * I tried to document those registers by looking at ar5k code, some

129 * As i can see in ar5k_ar5210_tx_start Reyk uses some of the values of BCR
130 * for this register, so i guess TQ1V,TQ1FV and BDMAE have the same meaning
131 * here and SNP/SNAP means "snapshot" (so this register gets synced with BCR).
132 * So SNAPPEDBCRVALID sould also stand for "snapped BCR -values- valid", so i
133 * renamed it to SNAPSHOTSVALID to make more sense. I realy have no idea what
134 * else can it be. I also renamed SNPBCMD to SNPADHOC to match BCR.

647 * with pending frames. Intra-frame lockout means we wait until
648 * the queue's current frame transmits (with post frame backoff and bursting)
649 * before we transmit anything else and global lockout means we
650 * wait for the whole queue to finish before higher priority queues
651 * can transmit (this is used on beacon and CAB queues).
652 * No lockout means there is no special handling.

816 * "General Purpose Input/Output" (GPIO) control register
818 * I'm not sure about this but after looking at the code
819 * for all chipsets here is what i got.
821 * We have 6 GPIOs (pins), each GPIO has 4 modes (2 bits)
822 * Mode 0 -> always input
823 * Mode 1 -> output when GPIODO for this GPIO is set to 0
824 * Mode 2 -> output when GPIODO for this GPIO is set to 1
825 * Mode 3 -> always output
827 * For more infos check out get_gpio/set_gpio and
828 * set_gpio_input/set_gpio_output functs.
829 * For more infos on gpio interrupt check out set_gpio_intr.

873 * status register is at 0x6c00. There is also
874 * no eeprom command register on 5210 and the

877 * To read eeprom data for a specific offset:
878 * 5210 - enable eeprom access (AR5K_PCICFG_EEAE)
879 * read AR5K_EEPROM_BASE +(4 * offset)
880 * check the eeprom status register
881 * and read eeprom data register.
883 * 5211 - write offset to AR5K_EEPROM_BASE
884 * 5212 write AR5K_EEPROM_CMD_READ on AR5K_EEPROM_CMD
885 * check the eeprom status register
886 * and read eeprom data register.
888 * To write eeprom data for a specific offset:

1735 * RF Buffer register
1737 * There are some special control registers on the RF chip
1738 * that hold various operation settings related mostly to
1739 * the analog parts (channel, gain adjustment etc).
1741 * We don't write on those registers directly but
1742 * we send a data packet on the buffer register and
1743 * then write on another special register to notify hw
1744 * to apply the settings. This is done so that control registers
1745 * can be dynamicaly programmed during operation and the settings
1746 * are applied faster on the hw.
1748 * We sent such data packets during rf initialization and channel change
1749 * through ath5k_hw_rf*_rfregs and ath5k_hw_rf*_channel functions.
1751 * The data packets we send during initializadion are inside ath5k_ini_rf
1752 * struct (see ath5k_hw.h) and each one is related to an "rf register bank".
1753 * We use *rfregs functions to modify them acording to current operation
1754 * mode and eeprom values and pass them all together to the chip.
1756 * It's obvious from the code that 0x989c is the buffer register but
1757 * for the other special registers that we write to after sending each
1758 * packet, i have no idea. So i'll name them BUFFER_CONTROL_X registers
1759 * for now. It's interesting that they are also used for some other operations.
1761 * Also check out hw.h and U.S. Patent 6677779 B1 (about buffer
1762 * registers and control registers):
