Let's take imx6qdl-sabresd.dtsi for example:
&pcie {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_pcie>;
reset-gpio = <&gpio7 12 0>;
status = "okay";
};
It uses GPIO7_12 for PCI reset.
For sabreauto we just need to change to something like this format:
reset-gpio = <&max7310_b 2 0>;

Yes, the signal is connected to power-on and it can also be
independently controlled via MAX7310.
Anyway, no need to change this if you don't want. I can send a patch
adding the reset later :-)
