Subject: [PATCH net 3/3] riscv: dts: thead: Add APB clocks for TH1520 GMACs
Date: Tue, 29 Jul 2025 09:37:34 +0000 [thread overview]
Message-ID: <20250729093734.40132-4-ziyao@disroot.org> (raw)
In-Reply-To: <20250729093734.40132-1-ziyao@disroot.org>
Describe perisys-apb4-hclk as the APB clock for TH1520 SoC, which is
essential for accessing GMAC glue registers.
Fixes: 7e756671a664 ("riscv: dts: thead: Add TH1520 ethernet nodes")
