[PATCH 2/2] arm64: dts: imx93-phyboard-segin: Add peb-av-02 overlay
Posted by Marco Felsch 2 months, 1 week ago
From: Andrej Picej <andrej.picej@norik.com>

Add overlay for Audio-Video module PEB-AV-02. Add support for panel
display, capacitive touchscreen and backlight.

For now the backlight is configured as a GPIO, brightness of the display
can not be set. When the FLEXIO PWM driver is available this should be
switched to PWM backlight driver.

Here you need to rebase since new commits on linux-next.

I just checked the schematics.

Can we rename this to reg_vcc_3v3_con in v2 maybe?

> +		compatible = "regulator-fixed";

And this to "VCC3V3_CON"?

The reasoning behind is that "X71-VCC3V3" voltage doesn't exist on the
schematics, while there is actually "VCC3V3_CON" voltage supplying the
display panel.

Please add "wakeup-source" property here like in the downstream commit.

With this in place, panel touch can be used to wake up the board from sleep.

Last but not least, can you add the vcc and iovcc supply regulators here
like in the downstream commit:

vcc-supply = <&reg_vcc_3v3_con>;
iovcc-supply = <&reg_vcc_3v3_con>;

to get rid of the following warnings:

edt_ft5x06 1-0038: supply vcc not found, using dummy regulator
edt_ft5x06 1-0038: supply iovcc not found, using dummy regulator

Anyway, I tested the display on the segin board with latest linux-next
and your patches. Can report display, touch and backlight work as expected.

Thank you!

I know that "X71-VCC3V3" doesn't exist, I also thought about
"X71:VCC3V3" to make it clear. Why I mentioned the X71 in the first
place was to not cause any naming conflict. I would like to keep the X71
naming since "VCC3V3_CON" really is the "X71-VCC3V3" with some filters
applied. Anyway, I can change this of course.

Is this a required feature? Touchscreens with no certain
low-power mode handlig (e.g. reduced scanning time) can draw much power
in suspend.

I can add it if Phytec is aware of this fact and still wants to have
thsi feature.

Will do.

Yes, please add this "wakeup-source" property again. This feature 
shall work on our platform by default. And one who wants to avoid
touchscreen as wakeup-source can modify the device-tree or disable 
it for wakeup via policy/sysfs.
