Subject: [PATCH 2/3] arm64: dts: allwinner: sun55i-a523: Add pinmux for spi0 on PJ pins
Date: Sat, 28 Feb 2026 01:51:54 +0800 [thread overview]
Message-ID: <20260227175157.2339758-3-wens@kernel.org> (raw)
In-Reply-To: <20260227175157.2339758-1-wens@kernel.org>
The Avaota A1 board uses spi0 on the PJ pins to connect a SPI NAND
chip.
Add the full set of pins. Even though this board doesn't use CS1, other
boards may do so in the future.
Signed-off-by: Chen-Yu Tsai <wens@kernel.org>
