Plus, quoting SubmittingPatches " When you submit or resubmit a patch or patch series, include the complete patch description and justification for it. Don't just say that this is version N of the patch (series). Don't expect the subsystem maintainer to refer back to earlier patch versions or referenced URLs to find the patch description and put that into the patch. I.e., the patch (series) and its description should be self-contained. " If the patch description is self-contained, there's no need for a URL. And I really don't care about the board description being comprehensive either, so there's nothing to edit. > > > +&i2c1 { > > > + pinctrl-names = "default"; > > > + pinctrl-0 = <&i2c1_pins_a>; > > > + status = "okay"; > > > + > > > + ctp at 5d { > > > + pinctrl-names = "default"; > > > + pinctrl-0 = <>911_int_primo81>; > > > + compatible = "goodix,gt911"; > > > + reg = <0x5d>; > > > + interrupt-parent = <&pio>; > > > + interrupts = <0 3 IRQ_TYPE_LEVEL_HIGH>; /* PA3 */ > > > + /* > > > + * The default 0,0 coordinate is at the corner closest to > > > + * the headphone jack.

I guess I'm not a human then, but a DT is definitely not the place I would look at for such information, and I'm not sure a user that didn't even build his kernel will either. However, I'm pretty sure that if it was in a wiki page, any search engine would return exactly the info I need, far more reliably than if it was in the kernel source.
