[PATCH v3 0/5] ARM: dts: imx27 Phytec phyCARD-S

[PATCH v3 0/5] ARM: dts: imx27 Phytec phyCARD-S

[Markus Pargmann]

Hi,

This series adds some device nodes for imx27 and board files for Phytec
phyCARD-S SOM and RDK. It is based on shawn's branch "imx/dt".

Regards,

Markus

Changes in v3:
 - Removed unnecessary clock-names from owire node
 - Update memory offset

Changes in v2:
 - Removed already accepted clocks patch
   "ARM: mx27: Replace clk_register_clkdev with clock DT lookup"
 - pca100 board file was splitted into two parts SOM and RDK
 - other changes described in patch notes

[PATCH v3 1/5] 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.

If it can be fixed while applying, it would be right to use just "fb" here.
We now use a lot of devices without "imx"-prefix, so I do not see any need to use it here.

I actually prefer to use the block name if it's not a thing defined by
ePAPR.  In this case, it's "lcdc".  But since "fb" is already used in
compatible.  Okay, I fixed it up by dropping "imx" prefix.

Applied the whole series, thanks.

[PATCH v3 4/5] 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.

Really two identical RTC on I2C1 & I2C2 or it is typo?

The commit ID is not stable.  I just dropped it and applied the patch.

There are a couple of comments on this file.

I think that the OWIRE should be moved to the RDK.

ioexpander must contain "gpio-controller" at least, and for use it further,
it is necessary to define the label for this node.

Thanks.

I moved OWIRE and i2c1 to RDK. Both are not used on the SOM.

I checked all I2C devices in the board schematics. There is actually no
ioexpander. I don't know why it was added. I will send some I2C patches
later.

Perhaps the chip is mounted on the camera module.
A similar IC is exist on PCM-970 camera addon device.
If so, the device should also be moved to RDK.

Yes that's possible. But in that case I think the ioexpander should be
removed from both dts files because the Phytec phyCARD-S RDK does not
include a camera module.
