[v3,6/9] arm64: dts: mediatek: Add MT8186 Krabby platform based Tentacruel / Tentacool

Commit Message

Chen-Yu Tsai Dec. 4, 2023, 8:40 a.m. UTC

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 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

While this makes things better, it's not correct. The i2c2 bus does not use the
trackpad pin. I would believe a better way is to have a node that holds both
trackpads and claims the pin for both at once. And that node not being the i2c bus
as there could be more devices on the bus and the pin would be taken regardless of
any trackpad probing , which is not right.
Another option is to disable parallel probing for the trackpads, such that when one
fails to probe, the pin is released and can be taken by the other one.

 From the newest DTS coding style document:

The following order of properties in device nodes is preferred:

1. compatible
2. reg
3. ranges
4. Standard/common properties (defined by common bindings, e.g. without
    vendor-prefixes)
5. Vendor-specific properties
6. status (if applicable)
7. Child nodes, where each node is preceded with a blank line

The "status" property is by default "okay", thus it can be omitted.

The above-described ordering follows this approach:

1. Most important properties start the node: compatible then bus addressing to
    match unit address.
2. Each node will have common properties in similar place.
3. Status is the last information to annotate that device node is or is not
    finished (board resources are needed).


#io-channel-cells goes after `reg` (same for the other instances) :-)

Why are you deleting the trackpad@15 node?

You can simply override the compatible, or actually omit the compatible string
in the *.dtsi file, and set just that in each board *.dts.

dtsi:
	trackpad_a: trackpad@15 {
		/* Compatible is set in each board dts */
		reg, interrupts, others
	}

dts:

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


other dts:

&trackpad_a {
	compatible = "hid-over-i2c";
};

Do you really need the phandle to bt-sco?

Also, this node describes a codec, so: "bt-sco-codec" please!

This phandle is unused...

This is a firmware issue: once the correct firmware is uploaded to linux-firmware
the dsp node can get enabled... so it we make sure that this happens before this
devicetree gets picked, we can avoid a second commit enabling audio.

After all, since we *want to* use the Xtensa DSP for audio, without it booted
sound won't work *anyway*.... so having the firmware in place can also be seen
as a direct dependency of the entire audio functionality.

P.S.: The FW that is distributed with ChromeOS works just fine!

There's no choice for now... even if this is not beautiful to see... but it's still
ok for me because we can revisit this later when the HW Prober mechanism will be
upstreamed.

Wishing for a checking tool now. :p

Ack (though it looks weird).

The original trackpad@15 comes from the base design and is used for all
models other than the ones with the conflicting component. Hence I believe
it should live in the base .dtsi.

The delete-node makes it much less likely to have any lingering properties.
These are not nodes that just differ in compatible strings like DSI panels.
They have incompatible bindings. For example, elan,ekth3000 uses "vcc-supply",
while "hid-over-i2c" uses "vdd-supply".

And going back to my previous argument, the base design used one specific
model which is carried over to all the other models.

Suppose I add a phandle to the original trackpad, and do

    /delete-node/ &trackpad;

Would that be better?

No. But the sound node probably should be referencing it and the dmic
node via DT instead of hardcoding the DAI and codec names in the machine
driver.

Anyway, will remove the label for now.

Looking at the machine driver code, it seems OK to remove them. So I
will.

Looks like this got handled directly in the machine driver.
Will remove.

That is still a workaround, and it also doesn't work because there are
no bindings nor code for the extra device node level.

We thought about this but this workaround would impact everyone else not
dealing with second source components.

Yes. I'll try that. Looking at the code it should work.

I have:

sof-audio-of-mt8186 10680000.adsp: Firmware info: version 2:0:0-5494c
sof-audio-of-mt8186 10680000.adsp: Firmware: ABI 3:22:1 Kernel ABI 3:23:0
sof-audio-of-mt8186 10680000.adsp: unknown sof_ext_man header type 3 size 0x30
sof-audio-of-mt8186 10680000.adsp: Firmware info: version 2:0:0-5494c

and it's still hanging.

And FTR, I think sound is also blocked on the it6505 audio support series.

Looks like I was still using the bad version due to module options...

After removing the options, I now have:

sof-audio-of-mt8186 10680000.adsp: DT DSP detected
sof-audio-of-mt8186 10680000.adsp: assigned reserved memory node memory@61000000
sof-audio-of-mt8186 10680000.adsp: Firmware info: version 2:0:0-714c6
sof-audio-of-mt8186 10680000.adsp: Firmware: ABI 3:22:1 Kernel ABI 3:23:0
sof-audio-of-mt8186 10680000.adsp: unknown sof_ext_man header type 3 size 0x30
sof-audio-of-mt8186 10680000.adsp: Firmware info: version 2:0:0-714c6
sof-audio-of-mt8186 10680000.adsp: Firmware: ABI 3:22:1 Kernel ABI 3:23:0

But sound is still deferring probe:

# cat /sys/kernel/debug/devices_deferred
sound    mt8186_mt6366_rt1019_rt5682s:
mt8186_mt6366_rt1019_rt5682s_dev_probe snd_soc_register_card fail

>>>>> The two devices both have two variants. The difference is a second

>>>>> The extra SKU IDs for the Tentacruel devices map to different sensor

>>>>> 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

Yes, this happens because of the missing IT6505 HDMI audio support - but it's not
giving any side effect anyway... in this case, as far as DT is concerned... there
will be no change, and no side effects on working parts of the system, so we can
(imo) upstream this even if the driver-code-only dependency is not there yet.

Cheers!
