Subject: [PATCH v2 1/3] dt-bindings: i2c: spacemit: add optional resets
Date: Fri, 19 Dec 2025 15:42:20 +0800 [thread overview]
Message-ID: <20251219-i2c-reset-v2-1-ad201a602e74@gmail.com> (raw)
In-Reply-To: <20251219-i2c-reset-v2-0-ad201a602e74@gmail.com>
The I2C controller requires a reset to ensure it starts from a clean state.
Add the 'resets' property to support this hardware requirement.
