316 * stm32f4_i2c_write_byte() - Write a byte in the data register
317 * @i2c_dev: Controller's private data
326 * stm32f4_i2c_write_msg() - Fill the data register in write mode
327 * @i2c_dev: Controller's private data
329 * This function fills the data register with I2C transfer buffer
367 * @i2c_dev: Controller's private data
390 * @i2c_dev: Controller's private data
392 * This function is called when a new data is received in data register
407 * for N-byte reception with N > 3, we do not have to read the data
409 * transferred finished event before reading data.
418 * For N byte reception with N > 3 we directly read data register
419 * until N-2 data.

431 * This function is called when a new data is received in the shift register
432 * but data register has not been read yet.
446 * before reading the last two bytes (data N-1 and N).
469 * received data byte, we have to enable NACK before reading N-2
