The Nova is a QCS8550 like the Retroid Pocket 6. ROCKNIX 20260901 already
carries its DTS (the RP6 one with an IL97680A 1280x960 landscape panel,
1280x960 touch and inverted sticks) and panel driver, so the kernel only
needs the DTB appended. Its compatible is retroidpocket,rpnova alone, so
every RP6 check gets a Nova entry: steamos-manager device file, the
InputPlumber keyboard target rule, update-package device sets, the power
plugin's name. Desktop Mode seeds no rotation and a 1280x960 mode for it.

Untested on hardware.
