* Broadcom Keypad Controller device tree bindings
Broadcom Keypad controller is used to interface a SoC with a matrix-type
keypad device. The keypad controller supports multiple row and column lines.
A key can be placed at each intersection of a unique row and a unique column.
The keypad controller can sense a key-press and key-release and report the
event using a interrupt to the cpu.
This binding is based on the matrix-keymap binding with the following
changes:
keypad,num-rows and keypad,num-columns are required.
Required SoC Specific Properties:
- compatible: should be "brcm,bcm-keypad"
- reg: physical base address of the controller and length of memory mapped
region.
- interrupts: The interrupt number to the cpu.
Board Specific Properties:
- keypad,num-rows: Number of row lines connected to the keypad
controller.
- keypad,num-columns: Number of column lines connected to the
keypad controller.
- col-debounce-filter-period: The debounce period for the Column filter.
KEYPAD_DEBOUNCE_1_ms = 0
KEYPAD_DEBOUNCE_2_ms = 1
KEYPAD_DEBOUNCE_4_ms = 2
KEYPAD_DEBOUNCE_8_ms = 3
KEYPAD_DEBOUNCE_16_ms = 4
KEYPAD_DEBOUNCE_32_ms = 5
KEYPAD_DEBOUNCE_64_ms = 6
KEYPAD_DEBOUNCE_128_ms = 7
- status-debounce-filter-period: The debounce period for the Status filter.
KEYPAD_DEBOUNCE_1_ms = 0
KEYPAD_DEBOUNCE_2_ms = 1
KEYPAD_DEBOUNCE_4_ms = 2
KEYPAD_DEBOUNCE_8_ms = 3
KEYPAD_DEBOUNCE_16_ms = 4
KEYPAD_DEBOUNCE_32_ms = 5
KEYPAD_DEBOUNCE_64_ms = 6
KEYPAD_DEBOUNCE_128_ms = 7
- row-output-enabled: An optional property indicating whether the row or
column is being used as output. If specified the row is being used
as the output. Else defaults to column.
- pull-up-enabled: An optional property indicating the Keypad scan mode.
If specified implies the keypad scan pull-up has been enabled.
- autorepeat: Boolean, Enable auto repeat feature of Linux input
subsystem (optional).
- linux,keymap: The keymap for keys as described in the binding document
devicetree/bindings/input/matrix-keymap.txt.
