Subject: [PATCH 3/3] arm64: dts: allwinner: sun55i-t527: avaota-a1: Add SPI NAND
Date: Sat, 28 Feb 2026 01:51:55 +0800	[thread overview]
Message-ID: <20260227175157.2339758-4-wens@kernel.org> (raw)
In-Reply-To: <20260227175157.2339758-1-wens@kernel.org>

The Avaota A1 board has a SPI NAND chip connected to spi0 on the PJ
pins with support for QSPI.

Enable spi0 and add a device node for the SPI NAND chip.
