[PATCH v2 0/3] Add panels used by Asus Zenbook A14

[Aleksandrs Vinarskis]

Add x3 panels used by the abovementined device. The laptop comes in
two variants

* UX3407RA, higher end, FHD+ OLED or WOXGA+ OLED panels
* UX3407QA, lower end, FHD+ OLED or FHD+ LCD panels

At last all three variants were succeffully tested. Device-tree change
to take advantage of Samsung driver for OLED panels [1] will come later
via separate series once this one lands to linux-next.
