Subject: [PATCH v3 2/2] arm64: dts: amlogic: Adjust USB PHY power supply references
Date: Thu, 22 May 2025 22:55:32 +0530	[thread overview]
Message-ID: <20250522172535.302064-2-linux.amoon@gmail.com> (raw)
In-Reply-To: <20250522172535.302064-1-linux.amoon@gmail.com>

According to the Odroid-N2 schematics, the micro-USB phy is powered
via a gpio-controlled regulator PWREN, updates the phy-supply to
correctly assign the power supply for usb2_phy.

Additionally, the USB3 combo port, which connects to the onboard
4-port USB hub, is powered by the main VCC_5V rail. Updated the
phy-supply to correctly assign vcc_5v for the USB controller node.

These changes ensure accurate power supply configuration for
USB components, improving hardware compatibility and power management.
