Subject: [PATCH v8 11/11] ARM: dts: aspeed: anacapa: Add SPI flash VCC supply
Date: Wed, 2 Sep 2026 18:21:23 +0800 [thread overview]
Message-ID: <20260902-anacapa-devlop-phase-devicetree-v8-11-69c8eb2a7cda@gmail.com> (raw)
In-Reply-To: <20260902-anacapa-devlop-phase-devicetree-v8-0-69c8eb2a7cda@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.
