Synaptic touch driver about pmos-oneplus6 HOT 1 CLOSED

Hey, that's quite an interesting find. I've noticed that sometimes when turning on the display it can take quite some time for the touch screen to start working, I'm not exactly sure why this is but I suspect it's just the TS taking some time to wake up.

Dmesg confirms this:

[    5.166483] rmi4_f01 rmi4-00.fn01: found RMI device, manufacturer: Synaptics, product: S3706B, fw id: 2827775
[    5.185231] input: Synaptics S3706B as /devices/rmi4-00/input/input2

There are potentially several explanation here:

• OnePlus reused the same driver for the OnePlus 6 as previous phones, what the mainline drivers reports is actually correct, and the S3320 driver used downstream only has that name for legacy reasons
• The mainline (RMI4) driver reports the wrong model.

I would be more inclined to trust the upstream driver, however I suspect the best option would be to locate some datasheet and manually verifying these claims.

I don't suspect that this issue would affect Gnome 40, I've used quite a few varied DEs on the device, they do not care what model your touch screen is, it either reports touches as intended, or it does not. In this case it does, I see no reason why that would change on Gnome 40.

I'll close this as there doesn't seem to be any issue here.
