Subject: [PATCH 2/3] arm64: dts: agilex5: define the i2c0 pins for pinctrl
Date: Thu, 29 Oct 2026 16:32:00 -0500	[thread overview]
Message-ID: <20261029213201.718625-2-dinguyen@kernel.org> (raw)
In-Reply-To: <20261029213201.718625-1-dinguyen@kernel.org>

Add the I2C pins definition to the Agilex5 SoCDK NAND daughter card. This
allows the I2C driver to use pinctrl on the pins to perform I2C recovery.
