Cze??,

I wonder if all boards (except maybe that Toradex set) use an active-low
PCIe reset and are now broken. Perhaps Toradex uses active-high and thus
works.

I'm really puzzled by this :-) With your patch applied I get following on
Toradex Apalis modules:

 DTS:         reset-gpio = <&gpio1 28 GPIO_ACTIVE_LOW>;
 dmesg:       imx6q-pcie 1ffc000.pcie: phy link never came up
 gpio:        gpio-28  (                    |reset               ) out hi
 pin voltage: 0V

 DTS:         reset-gpio = <&gpio1 28 GPIO_ACTIVE_HIGH>;
 dmesg:       ath9k 0000:01:00.0: enabling device (0140 -> 0142)
 gpio:        gpio-28  (                    |reset               ) out lo
 pin voltage: 3V3

So Toradex Apalis is actually active-high? Thanks.
