From d590025e9d57afd576dc34a89760017f152e0c59 Mon Sep 17 00:00:00 2001 From: Hendrik Hamerlinck Date: Wed, 13 Aug 2025 11:22:39 +0200 Subject: [PATCH 1/2] dt-bindings: riscv: spacemit: Add OrangePi RV2 board Document the compatible string for the OrangePi RV2 board [1]. The board is described as using the Ky X1 SoC, which, based on available downstream sources and testing, appears to be identical or very closely related to the SpacemiT K1 SoC [2].

The board is described as using the Ky X1 SoC, which, based on available downstream sources and testing, appears to be identical or very closely related to the SpacemiT K1 SoC [2]. The device tree is adapted from the OrangePi vendor tree [3], and similar integration can be found in the Banana Pi kernel tree [4], confirming SoC compatibility. The main difference with the current Banana Pi BPI-F3 tree is that status led is using GPIO_ACTIVE_LOW. This minimal device tree enables booting into a serial console with UART output and a blinking LED.
