Subject: [PATCH v1 2/3] arm64: dts: rockchip: rk3588-rock-5b-5bp-5t: Fix USB host phy-supply on Rock 5b-5bp-5t SbC
Date: Sat,  3 Jan 2026 14:01:18 +0530	[thread overview]
Message-ID: <20260103083232.9510-3-linux.amoon@gmail.com> (raw)
In-Reply-To: <20260103083232.9510-1-linux.amoon@gmail.com>

The USB host USB2 and USB3 on the Rock 5B, 5BP, and 5T is powered by the
USB_HOST_PWREN_H gpio pin which is used to enable vcc5v0_host host
regulator which ensures proper power sequencing and management for onboard
Double-USB-HOST.

Update the u2phy2_host node to reference the correct phy-supply.
