From 38f4aa34a5f737ea8588dac320d884cc2e762c03 Mon Sep 17 00:00:00 2001 From: Justin Klaassen justin@tidylabs.net Date: Tue, 25 Feb 2025 17:03:58 +0000 Subject: [PATCH] arm64: dts: rockchip: fix u2phy1_host status for NanoPi R4S
The u2phy1_host should always have the same status as usb_host1_ehci and usb_host1_ohci, otherwise the EHCI and OHCI drivers may be initialized for a disabled usb port.
Per the NanoPi R4S schematic, the phy-supply for u2phy1_host is set to the vdd_5v regulator.
