Subject: [PATCH 03/11] dt-bindings: usb: Add binding for Cypress cypd4226 I2C driver
Date: Mon, 24 Oct 2022 15:41:20 +0800 [thread overview]
Message-ID: <20221024074128.1113554-4-waynec@nvidia.com> (raw)
In-Reply-To: <20221024074128.1113554-1-waynec@nvidia.com>
add device-tree binding documentation for Cypress cypd4226 type-C
controller's I2C interface. It is a standard i2c slave with GPIO
input as IRQ interface.
