* Broadcom Keypad Controller device tree bindings
2+
3+
Broadcom Keypad controller is used to interface a SoC with a matrix-type
4+
keypad device. The keypad controller supports multiple row and column lines.
5+
A key can be placed at each intersection of a unique row and a unique column.
6+
The keypad controller can sense a key-press and key-release and report the
7+
event using a interrupt to the cpu.
8+
9+
This binding is based on the matrix-keymap binding with the following
10+
changes:
11+
12+
keypad,num-rows and keypad,num-columns are required.
13+
14+
Required SoC Specific Properties:
15+
- compatible: should be "brcm,bcm-keypad"
16+
17+
- reg: physical base address of the controller and length of memory mapped
18+
region.
19+
20+
- interrupts: The interrupt number to the cpu.
21+
22+
Board Specific Properties:
23+
- keypad,num-rows: Number of row lines connected to the keypad
24+
controller.
25+
26+
- keypad,num-columns: Number of column lines connected to the
27+
keypad controller.
28+
29+
- col-debounce-filter-period: The debounce period for the Column filter.

- row-output-enabled: An optional property indicating whether the row or
52+
column is being used as output. If specified the row is being used
53+
as the output. Else defaults to column.
54+
55+
- pull-up-enabled: An optional property indicating the Keypad scan mode.
56+
If specified implies the keypad scan pull-up has been enabled.
57+
58+
- autorepeat: Boolean, Enable auto repeat feature of Linux input
59+
subsystem (optional).
60+
61+
- linux,keymap: The keymap for keys as described in the binding document
62+
