Subject: [PATCH 5/9] arm64: dts: exynos: gs101: define USI12 with I2C configuration
Date: Sat, 27 Jan 2024 00:19:09 +0000	[thread overview]
Message-ID: <20240127001926.495769-6-andre.draszik@linaro.org> (raw)
In-Reply-To: <20240127001926.495769-1-andre.draszik@linaro.org>

On the gs101-oriole board, i2c bus 12 has various USB-related
controllers attached to it.

Note the selection of the USI protocol is intentionally left for the
board dts file.
