Subject: [PATCH 4/4] riscv: dts: thead: Add reset controllers of more subsystems for TH1520
Date: Mon, 1 Sep 2025 04:23:20 +0000 [thread overview]
Message-ID: <20250901042320.22865-5-ziyao@disroot.org> (raw)
In-Reply-To: <20250901042320.22865-1-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.
