Subject: [PATCH v3 01/11] dt-bindings: i2c: nomadik: add mobileye,eyeq5-i2c bindings and example
Date: Wed, 06 Mar 2024 18:59:21 +0100 [thread overview]
Message-ID: <20240306-mbly-i2c-v3-1-605f866aa4ec@bootlin.com> (raw)
In-Reply-To: <20240306-mbly-i2c-v3-0-605f866aa4ec@bootlin.com>
Add EyeQ5 bindings to the existing Nomadik I2C dt-bindings. Add the
EyeQ5-specific property behind a conditional. Add an example for this
compatible.
