One thing that cross my mind when writing the TrimSlice support and I
forgot to mention: Should these files be named ${soc}-${board}.dts or
${vendor}-${board}.dts (tegra-paz00.dts or toshiba-paz00.dts or
compal-paz00.dts). I'm OK either way; just want to follow any outside
expectations.

The other boards just have "memory" here; which is wrong?

That's a pretty odd I2C frequency...

I also don't know. I prefer compal for paz00 because Toshiba's code name was 
procyon (I think) and I don't want to change all the naming. Also Toshiba 
showed no interest in helping us, so I don't see why they should get the fame.

I just copy-pasted from harmony, I guess it doesn't matter.

no, 80000 is even ;-) Seriously, it just reflects the fact that the embedded 
controller bus runs at 80kHz. Even more seriously, reading "booting-without-
of.txt" in the Documentation/devicetree dir,

      | o PowerPC,970 at 0
      |   |- name = "PowerPC,970"
      |   |- device_type = "cpu"
      |   |- reg = <0>
      |   |- clock-frequency = <5f5e1000>
      |   |- 64-bit
      |   |- linux,phandle = <2>

 it looks like all clock-frequency values are hexadecimal. In this case even 
<400000> would be wrong (or the docu is --- ok, the docu is wrong).

Well, it's more about correctly defining what the HW is than advertising,
fame, or support!

define "what the HW is". Warning: the following list is purely fictitious. Any 
similarities between the companies or products mentiond, real or imaginary, 
are coincidental.

	- company A creates a cpu (only the IP) and license it to company N.
	- company N adds some more stuff around it (interfaces, gpu, ...) and 
creates real cpu hw.
	- company T likes the cpu and asks company C to build a computer around it
	- company C takes the evaluation board from company N, modifies it a bit, 
and builds a whole netbook around it
	- company T gets the netbook from company C and adds a operating system 
which will displeased their customers

So how would you define that hw? Or the real question, who made it? And please 
don't take my second argument too serious. I just expressed my anger in an 
improper way at an improper place. Sorry for that.

Both... I believe it should be "memory@<base address>".

Tegra20's memory base address is 0, so I assume the quoted example above
is correct then.

[PATCH v3 0/3] paz00 updates for 3.3

[Marc Dietrich]

Hi,

the following three patches are intended for the 3.3 merge window and are based
on linux-next.

The first one adds wakeup support similar to seaboard, but with the difference
that the wakeup gpio is connected to the embedded controller instead of a real
gpio key.

The second patch adds device tree support for the nvec driver. This way we can
make use of it without adding more platform devices to the board files (and it
is also modern to do so).

The final one adds device tree support for paz00. The way the nvec it is
initialized will probably change in the future, but we like to include it for
now as it makes debugging easier.

The patches are against linux-next from Oct 25th.

Thanks

Marc

Changes since v2
    - remove the mem= from the bootargs, this is handled by the memory property
      already
    - change the root device until the sdhci init order can be changed
    - do not init unused serial ports
    - add dt documentation for nvec
    - remove CONFIG_OF #ifdefs from nvec.c
    - exchange the order of patch 2 and 3
Changes since v1
    - replace addition of the embedded controller to the board file by a device-tree
      based implementation.

[PATCH 3/3] arm/dt: tegra: add dts file for paz00

[Marc Dietrich]

This adds a dts file for paz00. As a side effect, this also enables
the embedded controller which controls the keyboard, touchpad, power,
leds, and some other functions.

Don't you also want to disable serial at 70006400, or set a clock rate for
it?

I just didn't noticed its existance because I configured a maximum of four 
serial ports only, so it didn't showed up in the boot log.

[PATCH 3/3] arm/dt: tegra: add dts file for paz00

[Marc Dietrich]

This adds a dts file for paz00. As a side effect, this also enables
the embedded controller which controls the keyboard, touchpad, power,
leds, and some other functions.
