WebThe driver itself chooses what devices it supports. It does this programmatically, i.e. by checking the device's vendor and product ID, or, if those aren't available (e.g. an old device), performing some auto-detection heuristics and sanity checks. Once the driver is confident it's found a device it supports, it attaches itself to it. Webstruct i2c_driver *i2cdrv the I2C driver to register Description This function registers both i2cdev and i3cdev, and fails if one of these registrations fails. This is mainly useful for devices that support both I2C and I3C modes. Note that when CONFIG_I3C is not enabled, this function only registers the I2C driver. Return
