Hi Fabio,

I agree with reverting this - this patch does break PCI for all the
Gateworks Ventana boards.

It's Gateworks 'Ventana' here that uses IMX6 PCI, not Laguna so your
comment is wrong. Also, Ventana boards 'do' have their PCI reset
properly defined as active-low so we probably shouldn't refer to
Gateworks Ventana having gpio polarity not specified in the
device-tree.

It is the fact that the gpio polarity has the wrong logic level in
that patch which breaks things. I think your second point is really
the problem that needs to be mentioned for the reason of the revert.

Other than that you can add a 'Tested-by: Tim Harvey
<tharvey@xxxxxxxxxxxxx>' in reference to Gateworks Ventana PCI.

Thanks,

Tim
