Subject: [PATCH v7 11/11] ARM: dts: aspeed: anacapa: Add SPI flash VCC supply
Date: Tue, 01 Sep 2026 20:15:26 +0800 [thread overview]
Message-ID: <20260901-anacapa-devlop-phase-devicetree-v7-11-0bd71d2e0105@gmail.com> (raw)
In-Reply-To: <20260901-anacapa-devlop-phase-devicetree-v7-0-0bd71d2e0105@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.
