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):
It's not missing, it's there, just not controlled by the ath9k driver.
There is no separated radio (just the built-in one) on this platform so
all GPIOs belong to the main SOC and can be controlled with ath79-gpio.

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
