Subject: Re: [PATCH v2 2/2] arm64: dts: mediatek: add mt8173 elm and hana
board
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)
