Get GPIO pin overview (pinout)

On Banana Pi you can call:

$> gpio readall

This should give you an pinout like that:

+----------+-Rev2-+------+--------+------+-------+
| wiringPi | GPIO | Phys | Name   | Mode | Value |
+----------+------+------+--------+------+-------+
|      0   |  17  |  11  | GPIO 0 | OUT  | High  |
|      1   |  18  |  12  | GPIO 1 | ALT0 | High  |
|      2   |  27  |  13  | GPIO 2 | ALT4 | Low   |
|      3   |  22  |  15  | GPIO 3 | ALT4 | Low   |
|      4   |  23  |  16  | GPIO 4 | OUT  | High  |
|      5   |  24  |  18  | GPIO 5 | OUT  | Low   |
|      6   |  25  |  22  | GPIO 6 | ALT4 | Low   |
|      7   |   4  |   7  | GPIO 7 | IN   | Low   |
|      8   |   2  |   3  | SDA    | ALT5 | Low   |
|      9   |   3  |   5  | SCL    | ALT5 | Low   |
|     10   |   8  |  24  | CE0    | IN   | Low   |
|     11   |   7  |  26  | CE1    | IN   | Low   |
|     12   |  10  |  19  | MOSI   | IN   | Low   |
|     13   |   9  |  21  | MISO   | IN   | Low   |
|     14   |  11  |  23  | SCLK   | IN   | Low   |
|     15   |  14  |   8  | TxD    | ALT0 | High  |
|     16   |  15  |  10  | RxD    | ALT0 | High  |
|     17   |  28  |   3  | GPIO 8 | IN   | Low   |
|     18   |  29  |   4  | GPIO 9 | IN   | Low   |
|     19   |  30  |   5  | GPIO10 | OUT  | High  |
|     20   |  31  |   6  | GPIO11 | IN   | Low   |
+----------+------+------+--------+------+-------+

As you can see you also will see the current value of the pins.

If BCM (@see http://raspberrypi.stackexchange.com/questions/12966/what-is-the-difference-between-board-and-bcm-for-gpio-pin-numbering) is activated it should look like that (Banana Pi Pro):
