Subject: [PATCH 1/3] dt-bindings: i2c: spacemit: add optional resets
Date: Tue, 30 Dec 2025 23:06:51 +0800 [thread overview]
Message-ID: <20251230150653.42097-1-jyc0019@gmail.com> (raw)
In-Reply-To: <20251230-i2c-reset-v3-0-7500eb93b06e@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.
