You should include asm/prom.h to use the flattened device tree function.

Is this bus interface really board specific?  I would have thought the
localbus bridge would have been part of the SoC in which case the
compatible string should mention the 823 rather than the dbox.

> +		#address-cells = <1>;

It's also usual for these localbus things, to have #address-cells of
2, with the chipselect explicitly present as the first cell.

What are these mysterious enx, gtx, etc. devices?  Some comments might
be nice.

compatible strings should be listed with most specific first, most
general last.  That would put "cfi-flash" after the dbox2 specific
string, I believe.

Is this representing an LCD controller, or the display itself.  Either
way I'm surprised there's something here in the SoC that has a
compatible string that's not "fsl,something"

The setup of the localbus is already done in the boot loader. However, i'll
recode this to reflect the mapping of addresses to chipselects.

Those are mostly devices for video processing (MPEG demux, on screen display, MPEG decoder, etc).
Drivers (for ARCH=ppc) are available on cvs.tuxbox.org with GPL license. A work in progress port
to ARCH=powerpc is at git://git.bocc.de/dbox2.git.

It's a LCD controller wired to PortD. PortD is used for four 1bit lines
and one 8bit bus.

Would something like this be better?

CPM1_PIO: pio@970 {
	compatible = "fsl,cpm1-pario";
	reg = <970 180>;
	num-ports = <4>;
	#gpio-cells = <2>;
};

lcd@0 {
	compatible = "samsung,ks0713";
	gpio-parent = <&CPM1_PIO>;
	gpio-port = 3;
}

And then run gpio_request() for all lines on this port in the driver?

Thanks,
Jochen

is this really needed?  if so why.  we should work towards not having  
to do this going forward.

(I cant believe its needed since dbox2.h doesn't seem to have anything  
defined we'd need anywhere else).

Sure, that's normal.  But to the greatest extent possible, the device
tree should describe the hardware, not the configuration that's been
set up by the firmware/bootloader.  It's usually not possible to get
all the way there, but encoding the chipselect information this way
gets you closer.  It means that if you later need to adapt the device
tree to the same board with a firmware that does things differently,
only the "ranges" property should need changing.  Or, if you later
need a kernel port to a version with no-firmware or minimal firmware
that doesn't configure the bus, the necessary information is in the
tree to configure the bridge.

Ok.  Again, some comments so a casual read of the tree tells you
roughly what they are would be nice.

I'm still kind of confused here.  Does the pio@970 node above
represent the PortD controller?  If the LCD controller is accessed
solely through PortD, then it should be a child of the PortD node.

At present, pio and lcd have overlapping reg resources which is
certainly wrong.

pio@970 represent 4 ports (A-D). Ports A-C are used as GPIO lines. Port D
is exclusively used for the LCD, but it needs an 8bit accessor. Unfortunately,
the GPIO API doesn't have such an accessor, so the LCD driver needs to access
Port D itself and needs to make sure no other driver can access Port D via the
GPIO API. The representation as child of pio seems reasonable.

Thanks,

These unit addresses look wrong.

Maybe gpios should have a length field?  Or maybe we should just
phandle to a separate node under the gpio controller node.  What happens if
a device sits on two different gpio-parents?

Should have compatible of fsl,cpm-muram on the muram node as well, even
though the current code doesn't use it.

Why are we doing things differently just because all of the pins on this
port happen to be directed to one device?  If it's because the Linux GPIO
API sucks, then either fix the API, or work around the suckage in software,
not the device tree.

So some driver that matches on samsung,ks0713 has to know the details of the
mpc8xx GPIO registers?

Honestly, you're claiming derived-work status by calling a function that

I'd use separate device trees (I only did this kind of thing in mpc885ads
because it's dip-switchable), but whatever...

Hi Scott,

> These unit addresses look wrong.

I know. These have (hopefully) been fixed in v3.

> What does dbox2-config mean?

I used it to search for the vendor info byte in the flash. It has been moved to the boot wrapper in v3.
Later this should all be moved to u-boot, IMHO.

Overlay partition. Is there a better way to specify this?

The GPIO API only has an accessor for 1bit I/O. The LCD, however has for 1bit
control lines and an 8bit port. The GPIO API currently is unable to handle this.

In the meantime, i use the i2c patches from Jon Smirl and have added
these parameters.

Nope. It was a big fat hint not to use this value :). It has been moved to the
device tree in the mean time.

I don't really like having to use different images on different DBoxes. It's
already too much to have two images (there are two different flash layouts).
People tend to brick their box by flashing the wrong image.

Already gone in v3.

> What happens if a device sits on two different gpio-parents?

On the dbox2, there are even stranger devices. One is using iomaped address spaces, GPIO and an i2c control interface.
Another one uses GPIO and an i2c control interface. For now, they appear twice in the device tree (once under i2c and 
once under localbus or pio). Is there a better way to do this?

localbus@8000000 {
	cam@3,0 {
		compatible = "betaresearch,dbox2-cam";
		reg = <3 0 20000 6 0 20000>;
		interrupts = <6 2>;
		interrupt-parent = <&PIC>;
		gpios = <1 1c 1 1d 1 1e 1 1f>;
		gpio-parent = <&CPM1_PIO>;
	};
};
soc@ff000000 {
	cpm@9c0 {
		CPM1_PIO: pio@950 {
			fp@0,0 {
				compatible = "betaresearch,dbox2-fp";
				interrupts = <4 2>;
				interrupt-parent = <&PIC>;
				gpios = <0 e>;
				gpio-parent = <&CPM1_PIO>;
			};
		};
		i2c@860 {

				reg = <30>;
			};
			cam@37 {

	};
};

Right, but we shouldn't weird up the device tree because of Linux's 
weaknesses.  Ideally, the GPIO API should support wider I/O; in the 
meantime, there should be something in the board file that tells the 
ks0713 driver what to do.

I'd make the compatible name specific to the interface (e.g. 
"betaresearch,dbox2-cam-mmio", "betaresearch,dbox2-fp-i2c"), use reg 
rather than gpios/gpio-parent, and use phandle linkage between the 
different inteferfaces of a device.  But yes, multiple nodes is the 
sanest way to do it.
