Opi zero +2 H5 - pin 11 name?

[arjepsen]

Hey.

I'm working on setting up octoprint on my opi zero +2(H5), aiming at running octodash on a small 3.5" spi waveshare clone display.

So far I've got the display working fine, as in showing the console text, and also working in xorg.

However, I have a bit of trouble with the touch part.

 

I've combed through the forum and followed the guides I could find, and have a fairly good working DTS file, however, I can't seem to get pin number 11 to work.

In the overlay files, it seems to be named PA1, but I couldn't get that to work, and there were a bit of oddities with what pins seemed to be enabled, in relation to the various overlays.

However, I found different info here: https://linux-sunxi.org/Xunlong_Orange_Pi_Zero_Plus_2#Variants

suggesting that it's named PL0. Here, also pin 26 seems to be named PD14, which actually seems to be correct. But dmesg reports an error:

sun50i-h5-pinctrl 1c20800.pinctrl: unknown pin PL0
when I use that pin-name in the dts file.

 

Here's the DTS file I'm using:

 

/dts-v1/;
/plugin/;

Does anyone know the specific name to be used there?
