Subject: [PATCH v5 6/6] riscv: dts: spacemit: Add CTF2301 on K3 CoM260
Date: Mon, 14 Sep 2026 16:18:06 +0800	[thread overview]
Message-ID: <20260914-ctl2301-v5-6-522def70acb4@linux.dev> (raw)
In-Reply-To: <20260914-ctl2301-v5-0-b44b81cd2c3c@linux.dev>

Enable I2C6 on the K3 CoM260 module and describe the Sensylink
CTF2301 temperature sensor and fan controller at address 0x4c.

Override the I2C6 pin power source at board level because the IO rail
voltage is board-specific.
