This is one of two boards that make use of the recently introduced SIOX
bus. Apart from the devices described in the dts it features a display
with touch that I didn't include here because it needs some non-mainline
change to operate correctly.

Hello,

this addresses all but the two issued raised by Shawn that I didn't
understand. I use this patch as a reminder that my questions regarding
these are still open. :-)

Best regards
Uwe

Please use GPIO_ACTIVE_HIGH label for better readability.

Same here.

No 0x80000000 please. Use the real IOMUX setting here so that we don't
rely on the bootloader.

I guess you meant GPIO_ACTIVE_LOW here instead?

The reset-gpio polarity is ignored by the imx6 PCI driver and assumed
to be active low unless the "reset-gpio-active-high" is present.

I improved my tooling to catch these two problems. I found quite some
offenders, will send fixes after lunch.

Thanks for catching these.
