Subject: [PATCH 2/2] dt-bindings: riscv: Add Xuantie C906/C908/C910/C920 compatibles
Date: Sat, 15 Aug 2026 01:57:22 +0000 [thread overview]
Message-ID: <20260815015722.1736831-3-guoren@kernel.org> (raw)
In-Reply-To: <20260815015722.1736831-1-guoren@kernel.org>
From: "GUO Ren (XuanTie)" <guoren@kernel.org>
The RISC-V CPU bindings currently use the historical thead vendor
prefix for the XuanTie C906, C908, C910 and C920 processors.
Add equivalent compatibles using the newly defined xuantie vendor
prefix. Keep the existing thead compatibles to preserve compatibility
with existing device trees.
