[6/9] arm64: dts: mediatek: Add MT8186 Krabby platform based Tentacruel / Tentacool
Commit Message
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.

Hello Chen-Yu,
Thanks for the patch! However, there are a few things to improve...
the general shape of this looks mostly fine, but there's some comment, check below.

You don't need to delete the touchscreen node if you're disabling i2c1 entirely.
Besides, I'd rather see TS disabled by default, then enabled on a per-board-basis
as I think that this clarifies that "board X" has touchscreen, but "board Y" does
not, because it's "enabled" only on "board X".

All of them do have a WoWLAN event pin, but not all of them have got a pen
insertion pin... okay.
So, you should either set status = "disabled" to both and then enable them
in each board dts file, or you should merge them and delete the pen insertion
node wherever not present.
Using /delete-node/ is not wrong, of course, but I don't really like seeing
that... it's probably just boiling down to a personal preference, so, unless
you have strong opinions against that, I'd like to see the first suggestion
applied (status = disabled on all, enable on a per-board basis).

The adsp is default disabled, you don't need to set it to "fail", as this is
designed to work, not to fail, and this can be fixed.
When things cannot be "really" fixed, then I agree on setting status = "fail",
but again, this is not the case.

A "touchpad" is not an input device, it is a product name... so, this
is a "trackpad" instead :-)

Though, this compatible name is getting overridden in multiple cases, even if
the majority of the properties are effectively the same, as in, the interrupts
are the same, i2c addr is the same, power supplies are the same, pinctrl....
...what I would do here (even though it's a bit strange to see somehow) is...
trackpad: trackpad@15 {
/* Compatible string is be filled in board specific dts files */

pinctrl-0 = <&trackpad_pin>;
vcc-supply = <&pp3300_s3>;
wakeup-source;
}
In tentacruel-sku262144.dts:
&trackpad {

hid-descr-addr = <0x0001>;

pinctrl-names, pinctrl-0 here

The driver has this property, that's true, but I can't find that in the bindings.
Also, are you sure that we really need this?
Checking the it6505 driver, the lane swap could also be set/unset with
EXTCON_PROP_USB_TYPEC_POLARITY, check it6505_get_extcon_property()...
...but if we really need that property here, the bindings must have it.

Same question here.
P.S.: if yes, pins-cs-mosi-clk, pins-miso; if not, pins-bus.

Can we please rename this to "ppvar_dvdd_vgpu"?
The regulator coupler driver parses "vgpu"... :-)

Couple this regulator with VSRAM, max spread 100000.

Do we really need a phandle on cr50?
Also, I'd say tpm@0 instead.

Hi Chen-Yu,
The Krabby design has the touchscreen ? if the touchscreen is for
Tentacruel ,then the touchscreen should be described in the tentacruel
dtsi, not in the Krabby and then deleted for tentacool.
Or is there any reason for describing the touchscreen for Krabby ?
One additional way to solve this is to have the touchsreen as separate
dtsi and only include it for the boards that have it, e.g. tentacruel .

Yes. The Krabby design is the reference design and has all the bells and
whistles. Vendors can choose to drop features for their market segmenting
purposes.
In essence the vendors are taking a Google design and tweaking it to suite
their needs. Sometimes things get deleted. Deleting the node seems like
a proper way to describe it.

that they were "deleted" from the end product, so deleting the nodes also
makes sense.

The pin insertion "gpio-keys" node is a separate instance. So I assume
your comment applies to that one and not this one?
Merging them and then deleting the pin-insert node also requires overriding
the pinctrl property. Seems more work than necessary.
What you prefer here seems to be the opposite of what we have for the
touchscreen.

Actually I don't know what the general preference is, or what makes more

This probably needs to be figured out with all the type-C muxing stuff.

I'd just stick to gsc. The actual model used on these platforms is Ti50
anyway, which is the newer model. Either way they are called the Google
Security Chip, or GSC for short.
gsc_ap_int_odl is also what the line is called in the schematic.
For now I have:
gsc_int: gsc-int-pins {
pins-gsc-ap-int-odl {
What do you think?

OK... This is what the name is on the schematic. I'll fix the name

Hi Chen-Yu,
These two aud_gpio_tdm empty entries cause this message to be printed:

I guess we need to teach the sound driver to ignore empty pinmux states?

...and we need to teach to the bindings that the aud_gpio_tdm_{off,on} are
optional states and can be omitted.

Hello Angelo,
The binding does not appear to specify any required states. Am I getting this
wrong? Hence, we can just remove these states from the DT node.
Hello Chen-Yu,
The error message comes from the pinctrl, from dt_to_map_one_config() .
I believe we can safely just remove these two if corsola device does not use TDM.
From my perspective it is pointless to have two empty pinctrl states just for the
sake of it if there are no pins involved.
Please correct me if you have more knowledge about it.
Thanks,
Eugen
