GPIO Lookup Macros
^^^^^^^^^^^^^^^^^^
Some UART ports have dedicated IO_MUX pins to which they are connected directly. These can be useful if you need very high UART baud rates, which means you will have to use IO_MUX pins only. In other cases, any GPIO pin can be used for UART communication by routing the signals through the GPIO matrix. If the UART port has dedicated IO_MUX pins, :c:macro:`UART_NUM_x_TXD_DIRECT_GPIO_NUM` and :c:macro:`UART_NUM_x_RXD_DIRECT_GPIO_NUM` can be used to find the corresponding IO_MUX pin numbers.

The callback function, e.g., :cpp:member:`uhci_event_callbacks_t::on_tx_trans_done`, :cpp:member:`uhci_event_callbacks_t::on_rx_trans_event` and the functions invoked by itself should also reside in IRAM, users need to take care of this by themselves.

UART
----
``UART_FIFO_LEN`` macro has been removed. Please use ``UART_HW_FIFO_LEN`` instead.
- ``UART_FIFO_LEN`` macro has been removed. Please use ``UART_HW_FIFO_LEN`` instead.
- ``soc/uart_channel.h`` header file has been removed. All UART GPIO lookup macros can be found in ``soc/uart_pins.h``. For example, ``UART_NUM_0_TXD_DIRECT_GPIO_NUM`` is equivalent to ``U0TXD_GPIO_NUM``.
