[ath9k-devel] AR9287; mapping between GPIOs and COEX pins

[sandeep suresh <sandeep.suresh@yahoo.co.in>]

Hello Mr.Adrian,
????The card manufacturer like Compex systems for AR9287 has these pins available on PCIe interface. But my query is AR9287 specific. AR9287 is a 76 pin IC. GPIO4 is Pin22, GPIO5 is Pin23, GPIO6 is Pin 24 and so on. The question is if I need to access COEX signals (WL_ACTIVE, BT_ACTIVE, BT_PRIORITY, BT_FREQUENCY), on which of these 76 pins can I access them? Please help.
?
Regards
Sandeep.

It depends on what the card manufacturer has done.
