1
-A simple common binding for matrix-connected key boards. Currently targeted at
2
-defining the keys in the scope of linux key codes since that is a stable and
3
-standardized interface at this time.
4
-
5
-Required properties:
6
-- linux,keymap: an array of packed 1-cell entries containing the equivalent
7
- of row, column and linux key-code. The 32-bit big endian cell is packed
8
- as:
9
- row << 24 | column << 16 | key-code
10
-
11
-Optional properties:
12
-Properties for the number of rows and columns are optional because some
13
-drivers will use fixed values for these.
14
-- keypad,num-rows: Number of row lines connected to the keypad controller.
15
-- keypad,num-columns: Number of column lines connected to the keypad
16
- controller.

18
-Some users of this binding might choose to specify secondary keymaps for
19
-cases where there is a modifier key such as a Fn key. Proposed names
20
-for said properties are "linux,fn-keymap" or with another descriptive
21
-word for the modifier other from "Fn".

23
-Example:
24
- linux,keymap = < 0x00030012
25
- 0x0102003a >;
26
- keypad,num-rows = <2>;
27
- keypad,num-columns = <8>;
