This PR adds a sample for the touch controller. The sample is supposed to help examine issues when working with touchscreens. It draws a plus in the last touched position.

Can be tested natively with:

west build -p -b native_posix/native/64 samples/drivers/touch -t run

Thanks for the PR @fkokosinski!
FYI we already have a similar pending PR #67508 - while LVGL is slightly more heavyweight, it probably makes sense to converge to having only one sample?

@kartben I would go for the LVGL one and try to debulk it some more to make it easier for lower end targets.

Hey @kartben @faxe1008, thanks for your comments.

Ideally, we'd like this demo to work on smaller targets as well, where e.g. there's not enough space for LVGL. Plus, we think that having a kind of "minimal" demo with no additional library overhead can be beneficial when working on a new input driver, or debugging an old one. So we'd opt for keeping this demo separate from the one you've linked.

Let me know what you guys think. Thanks

Hey @kartben, let me know if there's something blocking us from moving forward with this PR. Thanks!

the first is already in boards/native/native_sim/native_sim.dts, it should not be needed here, the second should probably go in the board file, @kartben what do you think?

Looks very good. Only thing from my side: iirc there is a doc file which explains the different chosen nodes used in zephyr upstream. An entry there would be also good.

Great work, thanks!
@fkokosinski in the future please refrain from marking comments as resolved yourself - it's rather inconvenient to have to go through all closed conversations to check and, more importantly, it's up to the original reviewer to confirm their recommendations have been properly addressed. https://docs.zephyrproject.org/latest/contribute/contributor_expectations.html#workflow-suggestions-that-help-reviewers

Right, sorry about that. I'll keep this in mind in the future :)

The CI failure seems to be unrelated. On 8fda052 (main) I seem to be getting the exact same error when running west build -p -b esp32s3_touch_lcd_1_28/esp32s3/appcpu tests/lib/c_lib/common -T libraries.libc.common.
