Subject: [PATCH v3 5/5] riscv: dts: thead: Add reset controllers of more subsystems for TH1520
Date: Tue, 14 Oct 2025 13:10:32 +0000	[thread overview]
Message-ID: <20251014131032.49616-6-ziyao@disroot.org> (raw)
In-Reply-To: <20251014131032.49616-1-ziyao@disroot.org>

Describe reset controllers for VI, MISC, AP, DSP and AO subsystems. The
one for AO subsystem is marked as reserved, since it may be used by AON
firmware.
