Detailed Description

Driver for the Freescale Semiconductor MXC keypad port.

The keypad driver is designed as a standard Input driver which interacts with low level keypad port hardware. Upon opening, the Keypad driver initializes the keypad port. When the keypad interrupt happens the driver calles keypad polling timer and scans the keypad matrix for key press/release. If all key press/release happened it comes out of timer and waits for key press interrupt. The scancode for key press and release events are passed to Input subsytem.
