[OpenWrt-Devel] ath79/qca9533rev2: Help needed on missing GPIO on ath9k-phy0

[Adrian Schmutzler]

Hi,

we are still working on broken WiFi on CPE210v2/v3 (ath79, QCA9533 rev. 2) and have found that on ath79 a GPIO is missing compared to ar71xx (where WIFI is working):

GPIO Config on the ar71xx:

gpiochip0: GPIOs 0-31, parent: platform/ath79-gpio, ath79-gpio:
 gpio-11  (                    |tp-link:green:lan0  ) out hi    
 gpio-13  (                    |tp-link:green:link1 ) out hi    
 gpio-14  (                    |tp-link:green:link2 ) out hi    
 gpio-15  (                    |tp-link:green:link3 ) out hi    
 gpio-16  (                    |tp-link:green:link4 ) out hi    
 gpio-17  (                    |Reset button        ) in  hi    

gpiochip1: GPIOs 494-511, ath9k-phy0:
 gpio-495 (                    |ath9k-phy0          ) in  lo 


On the ath79:

 gpio-11  (                    |tp-link:green:lan   ) out lo    
 gpio-13  (                    |tp-link:green:link1 ) out hi    
 gpio-14  (                    |tp-link:green:link2 ) out hi    
 gpio-15  (                    |tp-link:green:link3 ) out hi    
 gpio-16  (                    |tp-link:green:link4 ) out hi    
 gpio-17  (                    |Reset button        ) in  hi


Can somebody point out how we can introduce the ath9k gpio? Or may this be already the result of something broken at an earlier step?

Best

Adrian
