A follow up to the display discussion thread [1] - Peter de Kraker has
tested these changes on his OLED setup, a few findings:
* OLED panel works out of the box, with `edp-panel`  compatible. Turns
on, turns Off on suspend, turns On on resume. Will update description
when respinning to reflect this.
* As per Bjorn Andersson's correction, the touchscreen was tested and
confirmed to be working with 0x10 address. No other i2c devices are
detected on that bus. Will update description when respinning to
reflect this.
* SKU/HWIDs of OLED and non-touch IPS models are 1:1 the same
* For reference, non-touch IPS panel is 'LQ134N1' according to EDID
