[PATCH 0/4] Devicetree support for Voipac i.MX53 module

[PATCH 0/4] Devicetree support for Voipac i.MX53 module

[Rostislav Lisovy]

This patchset adds devicetree definition for Voipac X53-DMM-668 module
which uses i.MX53 CPU. More information about the module may be found at:
http://www.voipac.com/#X53-DMM-668
The support for the baseboard used with this module is also provided.
More information about the baseboard: http://www.voipac.com/#X25-BSB-000

Working peripherals are:
* UART0
* Ethernet
* Buttons (with keyboard controller)
* Sound (headphone output)
* SD-card
* LEDs (through GPIOs)

This looks wrong. Any unit-address should match the first reg entry, and I've
not seen memory nodes with unit addresses anywhere else.

Why not:

memory {
	device_type = "memory";
	reg = <0x70000000 0x20000000>,
	      <0xb0000000 0x20000000>;
};

Is there any reason for placing these under a simple-bus rather than under the
root?

Thanks,
Mark.

This has already been fixed in the newer version of the patch.

IMHO readability, if more fixed regulators are likely to be added.

However "coding style" is wrong here. It should be something like:


	regulators {
		compatible = "simple-bus";
		#address-cells = <1>;
		#size-cells = <0>;

		reg_3p3v: regulator@0 {
			compatible = "regulator-fixed";
			reg = <0>;
			regulator-name = "3P3V";
			regulator-min-microvolt = <3300000>;
			regulator-max-microvolt = <3300000>;
			regulator-always-on;
		};
	};

Note #*-cells and reg properties and child node naming (generic name + 
@unit-address suffix).

Best regards,
Tomasz

Your Cc list looks a bit sparse. You should at least add
linux-arm-kernel-IAPFreCvJWM7uuMidbF8XUB+6BGkLq7r@public.gmane.org and Shawn Guo <shawn.guo-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>.

(Side note: You could use these devicetree files to probe from
devicetree for your barebox port.)

[PATCH 0/4] Devicetree description for Voipac i.MX53 module

[Rostislav Lisovy]

This patchset adds devicetree description for Voipac X53-DMM-668 module
which uses i.MX53 CPU. More information about the module may be found at:
http://www.voipac.com/#X53-DMM-668
The support for the baseboard used with this module is also provided.
More information about the baseboard: http://www.voipac.com/#X25-BSB-000

Working peripherals are:
* UART0
* Ethernet
* Buttons (with keyboard controller)
* Sound (headphone output)
* SD-card
* LEDs (through GPIOs)

The 'num' in memory@num should match the first number in 'reg' property,
so they should looks like:

	memory@70000000 {
		device_type = "memory";
		reg = <0x70000000 0x20000000>;
	}

	memory@b0000000 {
		device_type = "memory";
		reg = <0xb0000000 0x20000000>;
	}

Drop these blank lines.  We generally only have blank lines between

Please sort these nodes alphabetically in label name, so that new node

Dear Shawn;
Thank you for your comments.
Should I also add Voipac to
Documentation/devicetree/bindings/vendor-prefixes.txt?

Best regards;

I would agree with that, but why is your chosen prefix "vp" instead of
"voipac" anyway?

I saw that most of the vendor prefixes are somehow shortened (e.g.
Freescale -- fsl, etc.).

The 'fsl' is the stock symbol of Freescale.  If that's not the case for
voipac, I think 'voipac' is more appropriate.
