drm_i2c_encoder_destroy - Unregister the I2C device backing an encoder : Encoder to be unregistered.

This should be called from the method of an I2C slave encoder driver once I2C access is no longer needed.

int drm_i2c_encoder_init	(	struct drm_device *	dev,
		struct drm_encoder_slave *	encoder,
		struct i2c_adapter *	adap,
		const struct i2c_board_info *	info
	)

drm_i2c_encoder_init - Initialize an I2C slave encoder : DRM device. : Encoder to be attached to the I2C device. You aren't required to have called drm_encoder_init() before. : I2C adapter that will be used to communicate with the device. : Information that will be used to create the I2C device. Required fields are and .

Create an I2C device on the specified bus (the module containing its driver is transparently loaded) and attach it to the specified &drm_encoder_slave. The field will be initialized with the hooks provided by the slave driver.

If ->platform_data is non-NULL it will be used as the initial slave config.

Returns 0 on success or a negative errno on failure, in particular, -ENODEV is returned when no matching driver is found.
