[PATCH 1/2] ARM: dts: Add devicetree for Eckelmann CI4x10

[PATCH 1/2] ARM: dts: Add devicetree for Eckelmann CI4x10

[Uwe Kleine-König]

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.

As you dropped patch 1 the commit log of this patch is wrong. There is
no board that makes use of siox without the first patch. If you consider
it important enough to care, we can reword to:

	To increase compile coverage enable SIOX bus which is used on a
	not-yet-mainlined i.MX6 machine.

Uwe

Right, it's only the CPU that is produced by Freescale. So the implicit
associativity is: (Freescale i.MX6 DualLite) Eckelmann CI 4X10 Board :-)
I will make this "Eckelmann CI 4X10 Board".

Where is this supposed to be documented? I found
Documentation/devicetree/bindings/arm/fsl.txt but that only seems to
list Freescale reference boards and e.g. wand,imx6q-wandboard isn't
there (or anywhere else).

Documentation/devicetree/bindings/mtd/jedec,spi-nor.txt documents:

	compatible : May include a device-specific string consisting of the
	             manufacturer and name of the chip. A list of supported chip
		     names follows.

"everspin" is a documented manufacturer and "mr25h256" is included in
the referenced list. So it's unclear to me what is missing here.

Best regards
Uwe

[PATCH v2] ARM: dts: Add devicetree for Eckelmann CI4x10

[Uwe Kleine-König]

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.

Okay, I dropped this one from my tree.

You need to patch Documentation/devicetree/bindings/arm/fsl.yaml on my
imx/bindings (merged into for-next) branch.  Reminder - please keep
bindings change as a separate patch.

Just spot it - please use a generic node name.

Ah, okay.  It will make my searching of compatible much harder then.

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

Thanks for catching these.
