Subject: [PATCH 04/11] riscv: dts: sophgo: sg2044: Add I2C device
Date: Mon,  9 Jun 2025 07:28:28 +0800	[thread overview]
Message-ID: <20250608232836.784737-5-inochiama@gmail.com> (raw)
In-Reply-To: <20250608232836.784737-1-inochiama@gmail.com>

The I2C controller of SG2044 is a standard Synopsys IP, with one
the ref clock is need.

Add I2C DT node for SG2044 SoC.
