Subject: [PATCH v6 12/12] ARM: dts: aspeed: anacapa: Add SPI flash VCC supply
Date: Tue, 25 Aug 2026 18:47:53 +0800	[thread overview]
Message-ID: <20260825-anacapa-devlop-phase-devicetree-v6-12-9059a2a279ce@gmail.com> (raw)
In-Reply-To: <20260825-anacapa-devlop-phase-devicetree-v6-0-9059a2a279ce@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.
