  Tentacruel and Tentacool are MT8186 based Chromebooks based on the
Krabby design.

Tentacruel, also known as the ASUS Chromebook CM14 Flip CM1402F, is a
convertible device with touchscreen and stylus.

Tentacool, also known as the ASUS Chromebook CM14 CM1402C, is a laptop
device. It does not have a touchscreen or stylus.

The two devices both have two variants. The difference is a second
source touchpad controller that shares the same address as the original,
but is incompatible.

The extra SKU IDs for the Tentacruel devices map to different sensor
components attached to the Embedded Controller. These are not visible
to the main processor.

Changes since v3:
- Reorder some properties to conform better to the newly proposed DT
  style guidelines
- Drop unused labels
- Rename bt-sco node name to bt-sco-codec
- Drop i2s*-share properties from afe node
- Drop aud_gpio_tdm_{on,off} pinctrl nodes
- Replace interrupts with interrupts-extended in tpm node
- Enable adsp device

Changes since v2:
- Picked up Conor's ack
- Rename touchpad to trackpad
- Drop pinctrl properties from trackpad in tentacruel/tentacool second
  source trackpad

Changes since v1:
- Reorder SKU numbers in descending order.
- Fixed pinconfig node names
- Moved pinctrl-* properties after interrupts-*
- Switched to interrupts-extended for external components
- Marked ADSP as explicitly disabled, with a comment explaining that it
  stalls the system
- Renamed "touchpad" to "trackpad"
- Dropped bogus "no-laneswap" property from it6505 node
- Moved "realtek,jd-src" property to after all the regulator supplies
- Switched to macros for MT6366 regulator "regulator-allowed-modes"
- Renamed "vgpu" regulator name to allow coupling, with a comment
  containing the name used in the design
- Renamed "cr50" node name to "tpm"
- Moved trackpad_pins reference up to i2c2; workaround for second source
  component resource sharing.
- Fix copyright year
- Fixed touchscreen supply name

You forgot to change this one.

Remove compatible from this node and stop using /delete-node/ in device specific
devicetrees.

corsola.dtsi (here):

&i2c2 {
	pinctrl-names = "default";
	/*
	 * Trackpad pin put here to work around second source components
	 * sharing the pinmux in steelix designs.
	 */
	pinctrl-0 = <&i2c2_pins>, <&trackpad_pin>;
	clock-frequency = <400000>;
	i2c-scl-internal-delay-ns = <10000>;
	status = "okay";

	trackpad_i2c2_15: trackpad@15 {
		/*
		 * Those are common properties for i2c2 trackpad on Corsola boards.
		 * The compatible string is declared in device specific devicetrees
		 */
		reg = <0x15>;
		interrupts-extended = <&pio 11 IRQ_TYPE_LEVEL_LOW>;
		vcc-supply = <&pp3300_s3>;
		wakeup-source;
		status = "disabled";
	};
};

corsola-some-device.dts:

&trackpad_i2c2_15 {
	compatible = "hid-over-i2c";
	hid-descr-addr = <0x0001>;
	status = "okay";
};

corsola-some-other-device.dts:

&trackpad_i2c2_15 {
	compatible = "elan,ekth3000";
	status = "okay";
};

....everything else looks good.

Cheers,

One nit since you need to resend this anyway...

I believe I already replied to the previous version why we can't and shouldn't
do that.

"elan,ekth3000" and "hid-over-i2c" have incompatible bindings, specifically
the former uses "vcc-supply" while the latter uses "vdd-supply".

One has to track down if a property is a "sharable" property or not,
then put it in the correct place, otherwise getting DT binding validation
errors.

To me it seems cleaner to just delete the node wholesale to not have any
remnants of the original node, i.e. start from a clean slate. Trying to
"share" common properties is asking for a headache.

This feels more like a preference thing. I also asked if deleting the node
through the label would be cleaner, but you didn't reply.

Also, "elan,ekth3000" is the one that was designed and tested on the Corsola
reference design, so I think it rightfully belongs there. The Tentacruel
SKU replaced it with another part, so the original part should be disabled,
or in this case, deleted, because otherwise there would be a conflict.

Hello Chen-Yu,

There is still some nonconformity with the bindings, please see below:

Will add a patch to update the bindings.

Not sure why this is happening. Maybe because the sub-schema validation
failed?

In any case, I will drop the whole ports section. This can be re-added once
all the type-C mux stuff has been sorted out.

Thanks for the review. Since the merge window is just around the corner,
I will send a new version later this month.

I am truly sorry for not replying to that - and for replying to this one very late.

Ok, in that case, I still don't really like seeing /delete-node/ statements... and
unless there is a truly valid reason to have those, can we please just get each
node to each *.dts?

Just to clarify, a valid scenario to have a /delete-node/ statement there would be
the following:
  - Same platform, like Corsola in this case
  - Four devices
    - Three have one trackpad (better if expected more with the same TP)
    - One has the other trackpad

Even though I am flexible with that, I just don't see the value in deleting the
trackpad because we've got a 50-50 situation here!

At this point IMO it's worth defining the trackpad twice + twice instead... but
if you expect to have more devices, conforming to the valid scenario that I have
described above, then okay - keep going with /delete-node/.

If you really want to document the fact that the Corsola Reference Design
suggests to use a Elan eKTH3000 part, you can always leave a comment in the
dtsi, though, that's interesting mostly only to OEMs... but anyway I'm not
against having a comment, at all.

Angelo

It's not 50-50, because all the other MT8186 devices inherit the original
trackpad in mt8186-corsola.dtsi. So for those devices it either means
pushing it down to the next level in mt8186-corsola-steelix.dtsi, or
down to the individual .dts files, of which we already have six within
this series, and another two for the Voltorb devices. So that's 10 vs 2.

I think that makes a very valid case for using /delete-node/ and not
duplicating the device node everywhere?

Maybe we'll be able to clean this mess up a bit with overlays and FIT
images, but the FIT image stuff is still under discussion.
