* @param rx_buffer_size UART RX ring buffer size, rx_buffer_size should be greater than UART_FIFO_LEN.
* @param tx_buffer_size UART TX ring buffer size.
* If set to zero, driver will not use TX buffer, TX function will block task until all data have been sent out..
* @note tx_buffer_size should be greater than UART_FIFO_LEN.
*
* @param queue_size UART event queue size/depth.
* @param uart_queue UART event queue handle (out param). On success, a new queue handle is written here to provide
* access to UART events. If set to NULL, driver will not use an event queue.
