I'm a bit confused about all this versions. Do you want to keep them for
internal use, as I suppose only rev6 is available to the general public,
correct? I'm fine with keeping the old revisions if that's of use for you,
otherwise I'd prefer to delete them.
Model name could be more verbose.

In v1 you mentioned:
"Partners wants to increase touchpad and touchscreen source (they choose
synaptics) for hana 300e, and synaptics uses hid-over-i2c driver."
So the partner uses the same compatible (google,hana-rev6?) for both devices?

Hm, only defined for "realtek,rt5663", I suppose that's an inconsistency in the

no interrupts? binding description have this stated as required. what happens

According to internal feedback system, at least rev3, rev6, rev7 are
in general public. I can delete rev0~rev2, since they are earlier
version device.

As second source trackpad device and original device shares same
compatible string (rev id), we need to add 2nd trackpad node here.
According to previous log (since I don't have a second source trackpad
device to test), adding pinctrl in each trackpad node, there would be
error:

If we can't make this more verbose, at least delete rev0, that's confusing.
Should the name not be "Google Hana"?

If you don't plan to use the rev0 to rev2 in-house, then we can delete them.

We should create independent dts for the different boards. Like it is done for
gru-scarlett. Doesn't the FW provide the sku number in the compatible string?

Since I don't have a second source device to verify, I checked with
SIE, and he said the sku number(board id) are same for device using
original trackpad and second source trackpad in hana's case. So I
don't think we can split them to independent dts.

Here's a similar syscon node that is in a binding document's example:
syscfg_pctl_a: syscfg-pctl-a@10005000 {
compatible = "mediatek,mt8135-pctl-a-syscfg", "syscon";
reg = <0 0x10005000 0 0x1000>;
};

Yes I know, that's why I said that my first comment was not correct. Just leave
it in.

Hi Hsin-Yi,
Apart from the maintainer comments, a few more comments ...
cc'ing Matthias and Doug who I know played a bit with the pwm-backlight for the
uprev of the veyron devices, and you might be interested in his feedback in general.

That still looks weird to me. I don't have the touchscreen working yet so I can
really comment though.

The same for trackpads, still not working for me. There is no different
compatible to distinguish between the boards that have one or the other trackpad?

I think this should be in mt8173.dtsi?

nit: Not sure if you need to change or not, but this node is usually called
backlight: backlight without the _lcd. Note that this imply a userspace change
but /sys/class/backlight/backlight is more aligned with other boards (I guess)
when you have only one backlight. See for example:
git grep backlight arch/arm64/boot/*

The reason you see the display too dark is because userspace sets and remembers
the default value you have using the above configuration which is only 16
levels. So after removing the two above properties you should set a new
brightness from userspace.
AFAIK 16 levels is not enough to have fancy backlight effects on Chrome OS
userspace, at least is not enough for Rockchip devices so I suppose is the same
for Mediatek.
You have to options here.
A) Remove brightness-levels and default-brightness-level. This will end with a
non-linear brightness curve for the backlight up to 4095 levels.
# cat max_brightness
4095
B) Use the num-interpolated-steps and default-brightness-level properties. This
will end with a linear curve brightness. Similar to what is done for veyron
devices but in this case with more levels because the PWM to control the
backlight is 16-bits instead of 8-bits for veyron devices.

My guess is that you're interested on option B here to be coherent with other
Chromebooks.

You probably want stdout-path = "serial0:115200n8";
That way you'll get serial without needing to specify the console in the kernel
command line. Otherwise doesn't work because baudrate is missing.

Is this really a GPIO_ACTIVE_HIGH?
I still have problems with this, I need to comment this line and add
non-removable as a workaround in order to boot from the SD-card.
I think that the problem is that is GPIO_ACTIVE_LOW (it works for me, but I
don't have the schematics to confirm)

You could evaluate either way. One of the reasons to chose the interpolated-steps
for veyron was that some veyron panels require a minimum backlight level to
work properly. This can be easily configured with the linear curve, but
currently not with the non-linear one. Another reason was to keep the backlight
curve of a released device unaltered, though I think that's not strictly
required as long as the behavior with the non-linear curve is close/good enough.
Chrome OS user space supports both types of curves, for a new device I would
probably start with a non-linear curve, and only change that if the resulting
behavior doesn't meet expectations for some reason.
