Changes in v2:
- clarify exact Apalis iMX6Q/D SoM type in cover letter
- clarify exact Apalis iMX6Q/D module type and Ixora carrier board in model
  node
- got rid of obsolete mmc aliases
- working SGTL5000 audio/sound integration
- working STMPE811 touch screen controller integration
- integrated review feedback from Lucas
- left and even added some more comments as I don't see why putting any
  explanatory comments in dts' should be such a bad thing to do
- completely got rid of the memory node as that is something typically filled
  in by the boot loader e.g. U-Boot
- without the regulators simple-bus it no longer boots
- even though we supposedly shipped a few hundred V1.0a modules drop DCE UART
  support for now and simplify file layout
- replaced obsolete no-1-8-v by mainline supported voltage-ranges = <3300 3300>
  usdhc property and yes card detects are indeed active low (;-p)
- integrated review feedback from Stefan
- fixed Ethernet PHY reset & interrupt (requires Micrel PHY driver to be
  enabled)
- fixed HDMI DDC (requires GPIO-based bitbanging I2C to be enabled)
- fixed SPDIF

Hi Marcel,

thanks for taking care of this, I'm quite busy with other tasks :(

> - integrated review feedback from Lucas

You've probably missed few of them :) See my nitpicks bellow.

You've marked this as v2 so I think, that you should only work on the
feedback. Ideally you shouldn't add any new stuff if it wasn't requested
otherwise you're wasting reviewer time.

If I'm not mistaken, it wasn't requested by the reviewer.

It works for me on 4.4.0-rc3 with following DTS[1]. BTW, this DTS is my
preparation for v2 patch series.

Hope you've some kind of ACK from FSL and Linaro :)

I'm not sure, but it seems to me, that we should move this regulator into the
carrier board DTS. On our custom carrier board we've this regulator always on
and we use this GPIO for heartbeat LED, so I've this in our carrier board
DTS[2]:

	reg_usb_otg_vbus: usb_otg_vbus {
		/* Regulator is always on, and we use GPIO for heartbeat LED */
		pinctrl-0 = <>;
		gpio = <>;

		compatible = "regulator-fixed";
		regulator-name = "usb_otg_vbus";
		regulator-min-microvolt = <5000000>;
		regulator-max-microvolt = <5000000>;
		regulator-always-on;
	};

	...

	usbotg {
		/* GPIO3_IO22 is Heartbeat LED */
		pinctrl_regulator_usbotg_pwr: gpio_regulator_usbotg_pwr {
		};
	};

This was requested to be reworked. I've simply replaced all the macros with
hex values.

As per review comments, all hex values should be lowercase.

You're welcome. I know that feeling.

I don't think so but we don't necessarily agree with all of Lucas'
findings plus the discussion about some of the stuff hasn't really
concluded.

Well, as Stefan pointed out we at Toradex are/were working on this as
well and we discussed whether we should just ignore whatever you have
done or not done and post our own stuff but decided to rather join
efforts now as you already jumped ahead.

I don't think so. What is important is that any changes are clearly
declared which we did.

Lucas was actually nitpicking about the location thereof and rather
than moving it we decided to just get rid of it as it does not only not
add any value but is simply wrong on most of the modules featuring
different amount of memory.

I only tried with -next stuff so it might be something is just broken
there I guess.

Yeah, that one took us a day to figure it all out. At the end we
actually stumbled over your PCIe reset patch inverting the meaning of
active-low vs. active-high (;-p).

Well, all new DTS' are now dual-licensed including several i.MX 6
related ones so we are not doing anything special there really.

Yes, you are absolutely right and e.g. on Apalis T30 [1] that is
exactly how we did it.

I don't think the reviewers really concluded on the action to be taken
on here and just using hex values is probably the most stupid solution.

Yes, we probably missed that one.

Nit: The device tree bindings mention two more properties as required
properties:
micbias-resistor-k-ohms
micbias-voltage-m-volts

However, both have "If this node is not mentioned", hence I guess they
are actually optional, but maybe we want to set an explicit value here?

I think it is a convention to move iomuxc at the very end for better
readability of the rest. At least the Vybrid dts and the more recently
added imx7d-sdb.dts follow this rule.

The 80 character limit normally is not enforced for device trees, hence
I would remove that line break here...

I do not have a strong opinion on comments, but if they are pure
duplication of what is already there, I kind of prefer to not add
them...

...and this seem not to be specified upstream? (at least not in
Documentation/devicetree/bindings/mmc/mmc.txt?)
Not sure about this... Or is label a common convention and hence
available for all nodes?

They are accessible on the i.MX6 SoC.. but maybe "on Apalis iMX6Q/D". Or
just remove the comment, since that is kind of what disabled says?

Yes, that comment seems bogus and will be dropped.

And what about usdhc? It leads to the same overrides in the carrier board
file:

&iomuxc {
	usdhc {
		/* GPIO4_IO20 is LVDS */
		pinctrl_mmc_cd: gpio_mmc_cd {
		};

		/* Used as misc GPIOs */
		pinctrl_usdhc1: usdhc1grp {
		};
	};
};

It's simple, if you just leave it as it is, then it will never get merged.
That's how kernel development works :) We've at least two options here:

1. Follow the old path and just convert those macros to hex values
2. Rework it - move those macros to some header file etc.

According to one of the comments, it should be changed to the following:

		sda-gpios = <&gpio3 16 GPIO_ACTIVE_HIGH>;
		scl-gpios = <&gpio2 30 GPIO_ACTIVE_HIGH>;

Yes, the same applies here.

Thanks but I don't think you need to explain us how any of this works
(;-p).

Yes, stupid.

As mentioned before I don't think any agreement has been reached.

No, I believe you mixed the i2c-imx binding with the i2c-gpio one [2].
