Subject: [PATCH v4 12/12] ARM: dts: aspeed: anacapa: Add SPI flash VCC supply
Date: Wed, 05 Aug 2026 21:02:40 +0800 [thread overview]
Message-ID: <20260805-anacapa-devlop-phase-devicetree-v4-12-5d67e0efa6c5@gmail.com> (raw)
In-Reply-To: <20260805-anacapa-devlop-phase-devicetree-v4-0-5d67e0efa6c5@gmail.com>
From: Rex Fu <rex.fu.amd@gmail.com>
Specify the 3.3 V auxiliary rail as the SPI flash VCC supply to
avoid using the dummy regulator during device initialization.
