This driver is intended to control matrix keypads connected to i.MXL GPIOs (on [[APF9328]]). For [[APF27]] please use the i.MX27 internal keypad controller.

			The default keypad driver configuration supports 16 keys connected to the i.MXL CSI bus. The current development state of the driver is unfinished and not fully generic but you can easily extend the driver to support keypads up to 36 keys using the whole CSI bus.

==Introduction==
This driver is intented to control matrix keypads connected to i.MX GPIOs

==Installation==
If not already done in standard Armadeus rootfs:
$ make linux-menuconfig
Device Drivers ---> Input device support ---> [*] Keyboards ---> <*> AT keyboard
then
Device Drivers ---> Armadeus specific drivers ---> <M> Armadeus Keypad driver

Reflash rootfs then:
# modprobe imxkeypad
Initializing Armadeus keypad driver
input: imxkeypad as /class/input/input0

==Test==
* If you have a graphical LCD connected to your board (= virtual terminal), then you should see what you type.
* If you don't have any virtual terminal, but only the serial console:
# cat /sys/class/input/input0/event0/dev
13:64
If corresponding device node in /dev/input/ is not existing, then:
# mkdir -p /dev/input
# mknod /dev/input/event0 c 13 64

# cat /dev/input/event0
Then you should see weirds characters when pressing keyboard keys:
�,~~_�,}�}�3T,QToT6,TT�,�;��, � �
