[PATCH 0/9] arm64: dts: mediatek: Add MT8186 Corsola Chromebooks

[Chen-Yu Tsai]

Hi everyone,

This series adds device trees for the various MT8186 Chromebooks that
were initially released. These are the Tentacruel / Tentacool devices
released by ASUS, and the Steelix / Rusty / Magneton devices released
by Lenovo. The device trees are taken from the downstream ChromeOS v5.15
kernel, ported to mainline and cleaned up.

Corsola is the Google codename given to the MT8186 platform. This
platform has two reference designs, Krabby and Kingler. Kingler was not
used in any actual product, and is therefor not included. Steelix is
an alternative design put forward and is effectively a mix-and-match of
the two reference designs.

Most of the core design is shared between the variants. The differences
are on which external components, such as the display bridges, are used.

Patch 1 cleans up the current list of MediaTek boards. The entries are
reordered by SoC model first, then by board name.

Patch 2 through 5 add DT binding entries for the Tentacruel/Tentacool,
Steelix, Rusty, and Magneton Chromebooks.

Patch 6 through 9 add board device tree files for these devices. Patch 6
also adds the corsola dtsi file for the commonalities between the designs,
as well as a dtsi file for the krabby reference design.

Currently external display support is missing. Audio is not working, as
enabling the audio DSP causes my test systems to hang.

Please have a look and test if possible.


Regards
ChenYu

[PATCH 1/9] dt-bindings: arm: mediatek: Sort entries by SoC then board compatibles

[Chen-Yu Tsai]

Some of the new MediaTek board entries were inserted in a chronological
order, or just randomly. This makes it harder to search for an entry.

Sort the entries by first grouping by SoC, then sorting by board
compatible strings. Also add a comment at the top asking people to do
the same.

[PATCH 2/9] dt-bindings: arm: mediatek: Add MT8186 Tentacruel / Tentacool Chromebooks

[Chen-Yu Tsai]

Add entries for MT8186 based Tentacruel / Tentacool Chromebooks. The two
are based on the same board design: the former is a convertible device
with a touchscreen, stylus, and some extra buttons; the latter is a
clamshell device and lacks these additional features.

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.

Wha? Given your ordering, is a "google,tentacruel-sku262144" a super-set
of "google,tentacruel-sku262145"? If not, this compatible ordering
doesn't make sense. I can't tell from your description, and the
absence of a
items:
	  - const: google,tentacruel-sku262145
	  - const: google,tentacruel-sku262146
	  - const: google,tentacruel-sku262147
	  - const: google,tentacruel
	  - const: mediatek,mt8186
suggests that there is no google,tentacruel-sku262145
device?

Cheers,
Conor.

AFAIK all four SKUs exist. And as far as the main processor is concerned,
they look completely identical, so they should share the same device tree.
As mentioned in the commit message, the differences are only visible to
the embedded controller, which fuses the sensor inputs.

Writing it this way avoids having four identical device tree files.

We also do this for many other device families, though those cover
different revisions, such as:

      - description: Google Hana (Lenovo Chromebook N23 Yoga, C330, 300e,...)
        items:
          - const: google,hana-rev6
          - const: google,hana-rev5
          - const: google,hana-rev4
          - const: google,hana-rev3
          - const: google,hana
          - const: mediatek,mt8173

Then it makes very little sense to write a binding like this.
If this was just for the 252144 SKU, this would be fine.
For the other SKUs, there is no way to uniquely identify them, as
all four of google,tentacruel-sku262144, google,tentacruel-sku262145,
google,tentacruel-sku262146 and google,tentacruel-sku262147 must be
present.
Given that, why even bother including the SKUs in the first place,
since no information can be derived from them that cannot be derived
from google,tentacruel?
There's something that I am clearly missing here...

Also, why is the order inverted, with the lower SKUs being super-sets of
the higher ones? The Hana one you show below makes a little more sense
in that regard.

There are incompatible variants of google,tentacruel. This is why this
patch has four google,tentacruel based entries. Of them, two are Tentacool,
which are clamshell laptops, and two of them are Tentacruel, which are
convertibles.

Within each group there are two variants: the second variant swaps out
the I2C touchpad controller. These two controllers use the same I2C
address but use different compatible strings, so it's not possible to
have them coexist within the same device tree file like we do for many
other second source components.

So the relationship looks like the following:

google,tentacruel --- Tentacruel --- google,tentacruel-sku26214[4567]
                   |              |
                   |              -- google,tentacruel-sku2621{48,49,50,51}
                   |
                   -- Tentacool ---- google,tentacruel-sku327681
                                 |
                                 --- google,tentacruel-sku327683

Also, the devices themselves only know their own SKU ID. The firmware
will generate a list of compatible strings like:

  google,tentacruel-rev4-sku262144
  google,tentacruel-rev4
  google,tentacruel-sku262144
  google,tentacruel

and try to find a match in the kernel FIT image. The method we currently
use is to include all the applicable board compatible strings.

Either way works. The SKU IDs have no particular order. Nor do the
individual bits in the SKU ID have meaning. They are just arbitrarily
assigned by the manufacturer. They just have to all be present so any
of the SKUs will match.

Hope that explains things better.

Then it seems like what you need is something like
oneOf:
  - items:
      - const: google,tentacruel-sku262144
      - const: google,tentacruel
      - const: mediatek,mt8186
  - items:
      - enum:
          - google,tentacruel-sku262145
          - google,tentacruel-sku262146
          - google,tentacruel-sku262147
      - const: google,tentacruel-sku262144
      - const: google,tentacruel
      - const: mediatek,mt8186

What you have at the moment just seems like a hack because you want to
stuff all of these compatible strings into a single dts.

It is. And it works OK downstream. The reason we want to stuff them in
one dts is because the firmware will not generate the fallback to
sku262144 as the scheme above suggests.

Having three or four identical device trees just with different board
compatible string sequences to me seems a bit redundant, and it does
end up bloating our FIT image a bit, which impacts boot time.

I'm not going to ack the hack that you have here, sorry. Maybe Rob or
Krzysztof will. The list your firmware generates above doesn't even
match the contents of this patch, with the extra "rev-4" compatibles.

I'm not aware of the capabilities of your bootloader when it comes to
setting properties before passing them to the kernel, but that is what I
would be doing to cut down on having 4 different dtbs.

No Acks from me either... Chromebooks board compatibles are a long
standing confusion for me and every time I forget why this is so
counter-intuitively. My comments for changing this were rather receiving
feedback "but our firmware likes it that way".
OTOH, board compatibles just have to be unique, so we could accept some
weird, counter-intuitive combinations... but it does not mean I should
be happy with them.

Best regards,
Krzysztof

The firmware generates a list of compatibles that it will go through and
try to find a matching compatible with. I believe the intent was not to
use it as "a list of compatibles" in the usual sense. The kernel image
comes bundled with a whole bunch of device trees, and the firmware just
tries to find the best or most specific match. The firmware only knows
about itself, and does not know about adjacent or similar SKUs or
revisions.

The process is described in detail in the kernel tree in

    Documentation/arch/arm/google/chromebook-boot-flow.rst

or https://docs.kernel.org/arch/arm/google/chromebook-boot-flow.html

That could be a solution for future devices, but the devices this series
covers are already on the market. The firmware on these devices is very
hard to update, and there is no guarantee that the device ever gets
updated. Sometimes these extra SKUs or component changes happen after
the device is in production, due to inventory issues or EOL of components.
This is what happened here.

Then there's sometimes the problem where we are originally shipping with
downstream patches / bindings that may change as they are upstreamed.
This is something we are trying to fix by having our vendors upstream
earlier, but sometimes we do end up carrying some stuff downstream
regardless.

Also, doing the customization in firmware would be somewhat fragile as
we end up trying to keep two separate software packages in sync.


I talked to Doug Anderson about this, and his "of: device: Support 2nd
sources of probeable but undiscoverable devices" proposal (specifically,
the second proposal [1] after Rob nacked the first one) could help solve
this as well. Part of what we have with the Tentacruel series is second
source drop-in components, which is the same issue that the proposal
wants to solve.

Specifically, instead of the firmware solution you proposed, there would
be a hardware prober driver running early in the kernel that deals with
the board specifics, either by checking the SKU ID passed in by the
firmware (in inserted device tree nodes), or by manually probing the
hardware in some board specific way and tweaking the device tree to
match. It would know what needs to be handled for each device series.

With this scheme, we would be able to merge some of the device trees
together, though I'm not sure we would want to merge all of
"google,tentacruel", as that would also cover variants of different
form factors. I guess it depends on how much editing or probing we
want to allow in the board manager.

I had a chat with Doug at Plumbers about the limitations of your
firmware. As a result, I am fine with acking this if you switch the
order of the sku compatibles to be in descending order.
The firmware can handle that, right?

Cheers,
Conor.

Thank you for taking the effort to understand our weird firmware
implementation. And a thank you to Doug for discussing this. I'll
send out the next version shortly.

> The firmware can handle that, right?

Yes. The firmware basically takes a list of machine compatibles, and
runs them against all the DTs it has with of_machine_is_compatible().

This one makes sense though, because both of the SKUs are in an enum.

[PATCH 5/9] dt-bindings: arm: mediatek: Add MT8186 Magneton Chromebooks

[Chen-Yu Tsai]

Add entries for the MT8186 based Chromebooks, also collectively known
as the Lenovo IdeaPad Slim 3 Chromebook (14M868). It is also based on
the "Steelix" design. Being a laptop instead of a convertible device,
there is no touchscreen or stylus, which is similar to Rusty. However
Magneton does not have ports on the right side of the device.

Three variants are listed separately. These use different touchscreen
controllers, or lack a touchscreen altogether.

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

[Chen-Yu Tsai]

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 :-)

> +		compatible = "elan,ekth3000";

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 */
	reg = <0x15>;
	interrupts-extended = <&pio 11 IRQ_TYPE_LEVEL_LOW>;
	pinctrl-names = "default";
	pinctrl-0 = <&trackpad_pin>;
	vcc-supply = <&pp3300_s3>;
	wakeup-source;
}


In tentacruel-sku262144.dts:

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


In tentacool-sku327683.dts:

&trackpad {
	compatible = "elan,ekth3000";
};

pinctrl-names, pinctrl-0 here

> +		no-laneswap;

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.

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

Couple this regulator with VSRAM, max spread 100000.

Couple with VGPU, same max spread.

Do we really need a phandle on cr50?

Also, I'd say tpm@0 instead.

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
sense.

This probably needs to be figured out with all the type-C muxing stuff.
I'll drop it.

I can see some sense in that. Moved.

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?

I believe you meant "disp-pwm-pins"?

First level node requires "-pins$", not "^pins".

Looks like I need to update this to use the macros from the header file.

and add a comment for it.

Dropped label and renamed node to tpm.


Thanks for the review. I think at some point I messed up my files and
that resulted in a bunch of things that I fixed up getting reverted.

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.

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

[Chen-Yu Tsai]

The MT8186 Steelix, also known as the Lenovo 300e Yoga Chromebook Gen 4,
is a convertible device based on a common design of the same name. The
device comes in different variants. Of them, whether a world facing
camera is integrated is the only differentiating factor between the
two device trees added. The different SKU IDs describe this alone.

The other device difference is the touchpad component used. This is
simply handled by having both possible components described in the
device tree, and letting the implementation figure out which one is
actually available. The system bootloader / firmware does not
differentiate this in that they share the same SKU IDs.

Hi Chen-Yu,

This is not okay, the `trackpad_pin` is shared with touchpad@15 , and if 
drivers are probed in parallel , this can lead to a conflict on this pin 
(GPIO11)

You're right. I've moved it under i2c2 for now, as we do for other platforms
with second source components.

This should hopefully be cleaned up once we have a hardware prober.

[PATCH 8/9] arm64: dts: mediatek: Add MT8186 Steelix platform based Rusty

[Chen-Yu Tsai]

MT8186 Rusty, otherwise known as the Lenovo 100e Chromebook Gen 4, is an
MT8186 based laptop. It is based on the "Steelix" design. Being a laptop
instead of a convertible device, there is no touchscreen or stylus.

[PATCH 9/9] arm64: dts: mediatek: Add MT8186 Magneton Chromebooks

[Chen-Yu Tsai]

Add entries for the MT8186 based Chromebooks, also collectively known
as the Lenovo IdeaPad Slim 3 Chromebook (14M868). It is also based on
the "Steelix" design. Being a laptop instead of a convertible device,
there is no touchscreen or stylus, which is similar to Rusty. However
Magneton does not have ports on the right side of the device.

Three variants are listed separately. These use different touchscreen
controllers, or lack a touchscreen altogether.
