Subject: [PATCH v4 6/6] arm64: dts: rockchip: Add naneng-combphy for RK3528
Date: Tue, 24 Jun 2025 03:37:33 +0000	[thread overview]
Message-ID: <20250624033733.50197-7-ziyao@disroot.org> (raw)
In-Reply-To: <20250624033733.50197-1-ziyao@disroot.org>

Rockchip RK3528 ships a naneng-combphy that is shared by PCIe and USB
3.0 controllers. Describe it and the pipe-phy grf which it depends on.
