Subject: [PATCH v2 2/2] i2c: imx: Retry failed transfers 3 times
Date: Fri, 24 Apr 2026 13:36:47 +0100 [thread overview]
Message-ID: <20260424-i2c-imx-fixes-v2-2-34fb9504aaeb@ideasonboard.com> (raw)
In-Reply-To: <20260424-i2c-imx-fixes-v2-0-34fb9504aaeb@ideasonboard.com>
Set the retries member of the i2c_adapter to 3, which will cause the
i2c-core code to retry transfers that lose arbitration 3 times before
giving up.
