'disable-gpio' is not a valid property according to Documentation/devicetree/bindings/pci/fsl,imx6q-pcie.txt. Remove the unsupported property. Signed-off-by: Fabio Estevam <festevam@gmail.com>
Reviewed-by: Matthias Schiffer <redacted> This is a remnant of linux-imx, which supports the property. On the MBa7x (and likely other boards in linux-imx that use this), the GPIO is connected to mPCIe pin 20 (wireless_disable#). Is there an intended way to control this pin, or should it just be left unconfigured or hogged? power-on-gpio seems to be obsolete too, I can't even find it in current linux-imx, except for one other i.MX7D-based DTS. I can send a patch to remove that as well, but it might take a while until I get to it.
