[PATCH 0/6] ARM: dts: imx27 Phytec PhyCARD-S

[Markus Pargmann]

Hi,

This series adds some device nodes for imx27 and a board file for Phytec
PhyCARD-S. It is based on shawn's branch "imx/dt".

Regards,

Markus

Clock is not used in the gpio driver, so I doubt the usefulness of this patch.

I think you meant "this hunk", right?

My original patch did not have this part. It was added by Markus as
mentioned in the commit log, and I agree we should go with the
original version that did not add the gpio clock.

I somehow missed that your patch was applied in march. gpio clocks are
not mentioned in the binding documentation, so I drop this one
completely.

I somehow missed that your patch was applied in march. gpio clocks are
not mentioned in the binding documentation, so I drop this one
completely.

Thanks,

[PATCH 2/6] ARM: imx27: Use 'AITC' for the interrupt controller name

[Markus Pargmann]

From: Fabio Estevam <festevam@gmail.com>

On the MX27 Reference Manual the interrupt controller is named AITC:
ARM926EJ-S Interrupt Controller

So use the AITC term instead of AVIC.

I think you should use "fsl,imx27-owire", "fsl,imx21-owire" here.

[PATCH 5/6] ARM: dts: imx27 cpufreq-cpu0 frequencies

[Markus Pargmann]

Set operating-points for imx27. There is no regulator support, so the
voltages are 0. The frequencies should be the same for all imx27 boards,
so it is defined here and can be overwritten if necessary.

>From what Documentation/devicetree/bindings/arm/cpus.txt tells, it
should be "arm,arm926".  Also, why do you put "fsl,imx27" there?
"imx27" is a SoC name not cpu core.

"imx27" is a SoC name not cpu core.

I think Markus take this ARM property from one of existing DTS.

shc at shc /home/git/linux-mx27/arch/arm/boot/dts $ grep arm926 *.dtsi
at91sam9260.dtsi:                       compatible = "arm,arm926ejs";
at91sam9263.dtsi:                       compatible = "arm,arm926ejs";
at91sam9g45.dtsi:                       compatible = "arm,arm926ejs";
at91sam9n12.dtsi:                       compatible = "arm,arm926ejs";
at91sam9x5.dtsi:                        compatible = "arm,arm926ejs";
imx23.dtsi:                     compatible = "arm,arm926ejs";
imx28.dtsi:                     compatible = "arm,arm926ejs";
lpc32xx.dtsi:                   compatible = "arm,arm926ejs";
s3c2416.dtsi:                   compatible = "arm,arm926ejs";
spear3xx.dtsi:                  compatible = "arm,arm926ejs";
spear600.dtsi:                  compatible = "arm,arm926ejs";
wm8505.dtsi:                    compatible = "arm,arm926ejs";

So, documentation need to be updated or these values should be fixed.
Another solution  is specify compatible string as:
compatible = "arm,arm926ejs", "arm,arm926";
What you think about this?

I assume that the compatible string in the binding doc has been reviewed
and agreed by people, so we should fix the existing users before kernel
starts using it to for matching something.

I patched them all and changes are queued through arm-soc, according to the
latest bindings that should get merged this cycle and are available here:

git://linux-arm.org/linux-2.6-lp.git dt-cpus-bindings

If you are queuing dts updates please follow rules in there, waiting for
that document to get merged.

It's been covered by skeleton.dtsi.

They are only needed if there are child nodes with "reg" property.

Are these documented/accepted bindings?

People are against the idea of putting partition layout in device tree.
