Subject: [PATCH 7/8] arm64: dts: allwinner: orangepi-zero2: Describe the SPI NOR supply
Date: Tue, 10 Nov 2026 05:37:01 +0000 [thread overview]
Message-ID: <20261110-h616-zero2-dt-v1-7-05506d760f21@gmail.com> (raw)
In-Reply-To: <20261110-h616-zero2-dt-v1-0-05506d760f21@gmail.com>
From: Arun Iyengar <aiyengar1990@gmail.com>
The SPI NOR core requests a "vcc" supply for the flash. It is not
described for the Orange Pi Zero2, so the core falls back to a dummy
regulator and logs at boot:
spi-nor spi0.0: supply vcc not found, using dummy regulator
Per the Orange Pi Zero2 v1.3 schematic, the 2 MiB SPI NOR flash on SPI0
(port PC) is powered from the 3.3 V VCC-IO rail generated by ALDO1,
which already supplies port PC here. Describe it.
