[PATCH v5 12/15] ARM: dts: aspeed: anacapa: Add SPI flash VCC supply

From: Colin Huang via B4 Relay

Date: Thu Aug 13 2026 - 08:06:08 EST


From: Rex Fu <rex.fu.amd@xxxxxxxxx>

Specify the 3.3 V auxiliary rail as the SPI flash VCC supply to
avoid using the dummy regulator during device initialization.
