Subject: [PATCH 1/2] dt-bindings: arm: rockchip: Asus Tinkerboard 3 and 3S

From: [email-masked]
Date: Tue, 11 Nov 2025 17:20:22 +0000 (UTC)

From: Michael Opdenacker <[email-masked]>

Document the compatible strings for Asus Tinkerboard 3 [1] and 3S [2],
which are SBCs based on the Rockchip 3566 SoC.

The "3S" version ("S" for "storage") just adds a 16 GB eMMC
and a "mask ROM" DIP switch to the "3" version.
