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.
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
9 row << 24 | column << 16 | key-code
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
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".
24 linux,keymap = < 0x00030012
25 0x0102003a >;
26 keypad,num-rows = <2>;
27 keypad,num-columns = <8>;
