Subject: [PATCH 4/6] arm64: dts: qcom: qcs6490-radxa-dragon-q6a: Add regulator supplies and disable EUD
Date: Fri, 22 May 2026 18:06:43 +1200	[thread overview]
Message-ID: <20260522060645.4399-5-graham.oconnor@gmail.com> (raw)
In-Reply-To: <20260522060645.4399-1-graham.oconnor@gmail.com>

Add missing regulator supplies for qfprom and the PCIe controllers.
The qfprom node requires vcc-supply for correct eFuse reading. The
PCIe controllers require vdda and vddpe-3v3 supplies for the PHY and
connector power rails.

Disable the Embedded USB Debugger (EUD) as it conflicts with normal
USB operation on this board.

Tested on Radxa Dragon Q6A (QCS6490)
