-* Freescale i.MX Keypad Port(KPP) device tree bindings
-
-The KPP is designed to interface with a keypad matrix with 2-point contact
-or 3-point contact keys. The KPP is designed to simplify the software task
-of scanning a keypad matrix. The KPP is capable of detecting, debouncing,
-and decoding one or multiple keys pressed simultaneously on a keypad.
-
-Required SoC Specific Properties:
-- compatible: Should be "fsl,<soc>-kpp".
-
-- reg: Physical base address of the KPP and length of memory mapped
- region.
-
-- interrupts: The KPP interrupt number to the CPU(s).
-
-- clocks: The clock provided by the SoC to the KPP. Some SoCs use dummy
-clock(The clock for the KPP is provided by the SoCs automatically).
-
-Required Board Specific Properties:
-- pinctrl-names: The definition can be found at
-pinctrl/pinctrl-bindings.txt.
-
-- pinctrl-0: The definition can be found at

Can you please convert matrix-keymap.txt to a schema first and then
include in here.
