+description: |
+  GPIO driven mt matrix keypad is used to interface a SoC with a mt matrix
+  keypad. The mt matrix keypad supports multiple gpio line, all gpio line act
+  as row as wel as column lines, a key can be placed at each intersection
+  of a unique row number not equal to a unique column and they are diagonally
+  symmetric.
+
+  Example- For 5 gpio lines, possible matrix is 5x5 and maximum possible
+        keys are 10.
+
+        Sample matrix table for 7 button and 5 gpio line
+
+        ------------------------------------------------------
+        |Row\Col |GPIO 0 | GPIO 1 | GPIO 2 | GPIO 3 | GPIO 4 |
+        ------------------------------------------------------
+        | GPIO 0 |  X    | KEY_9  | KEY_2  |   X    | KEY_1  |
+        ------------------------------------------------------
+        | GPIO 1 | KEY_9 |  X     | KEY_6  |   X    |  X     |
+        ------------------------------------------------------
+        | GPIO 2 | KEY_2 | KEY_6  |  X     | KEY_4  | KEY_7  |
+        ------------------------------------------------------
+        | GPIO 3 |  X    |  X     | KEY_4  |  X     | KEY_8  |
+        ------------------------------------------------------
+        | GPIO 4 | KEY_1 |  X     | KEY_7  | KEY_8  |  X     |
+        ------------------------------------------------------
+        X - invalid key
+        KEY_x - preferred key code
+
+  The mt matrix keypad can sense a key-press and key-release by means of GPIO
+  lines and report the event using GPIO interrupts to the cpu.
