Subject: [PATCH v5 5/6] riscv: dts: spacemit: Add K3 I2C6 pinctrl state
Date: Mon, 14 Sep 2026 16:18:05 +0800	[thread overview]
Message-ID: <20260914-ctl2301-v5-5-522def70acb4@linux.dev> (raw)
In-Reply-To: <20260914-ctl2301-v5-0-b44b81cd2c3c@linux.dev>

Add the K3 I2C6 pinctrl state used by boards that route I2C6 to pads 7
and 8. Use a 25 mA drive strength, which is supported for both K3 IO
voltage domains, and leave board-specific IO voltage selection to board
files.
