Subject: [PATCH v3 1/2] arm64: dts: amlogic: Update USB hub power and reset properties
Date: Thu, 22 May 2025 22:55:31 +0530	[thread overview]
Message-ID: <20250522172535.302064-1-linux.amoon@gmail.com> (raw)

Add missing reset-gpios property to the USB 2.0 hub node to
ensure proper reset handling. Also update the vdd-supply for
both USB 2.0 and 3.0 hubs to use the shared hub_5v regulator
for consistent power management.

Fixes: ccff36934137 ("arm64: dts: amlogic: Used onboard usb hub reset on odroid n2")
Signed-off-by: Anand Moon <linux.amoon@gmail.com>
---
v3: dropped remove of usb2_phy1.
v2: remove usb2_phy1 phy-supply since now it's managed by
the hub reset control.
