When registering, you probably need to set the i2c + struct i2c_algorithm. When registering, you probably need to set the I2C slave address and enable slave specific interrupts. If you use runtime pm, you should use pm_runtime_get_sync() because your device usually needs to be powered on always to be able to detect its slave address. When unregistering, |
