* Tegra keyboard controller
The key controller has maximum 24 pins to make matrix keypad. Any pin
can be configured as row or column. The maximum column pin can be 8
and maximum row pins can be 16 for Tegra20/Tegra30.
Required properties:
- compatible: "nvidia,tegra20-kbc"
- reg: Register base address of KBC.
- interrupts: Interrupt number for the KBC.
- nvidia,kbc-row-pins: The KBC pins which are configured as row. This is an
array of pin numbers which is used as rows.
- nvidia,kbc-col-pins: The KBC pins which are configured as column. This is an
array of pin numbers which is used as column.
- linux,keymap: The keymap for keys as described in the binding document
devicetree/bindings/input/matrix-keymap.txt.
- clocks: Must contain one entry, for the module clock.
See ../clocks/clock-bindings.txt for details.
- resets: Must contain an entry for each entry in reset-names.
See ../reset/reset.txt for details.
- reset-names: Must include the following entries:
- kbc
Optional properties, in addition to those specified by the shared
matrix-keyboard bindings:
- linux,fn-keymap: a second keymap, same specification as the
matrix-keyboard-controller spec but to be used when the KEY_FN modifier
key is pressed.
- nvidia,debounce-delay-ms: delay in milliseconds per row scan for debouncing
- nvidia,repeat-delay-ms: delay in milliseconds before repeat starts
- nvidia,ghost-filter: enable ghost filtering for this device
- nvidia,wakeup-source: configure keyboard as a wakeup source for suspend/resume
Example:
keyboard: keyboard {
compatible = "nvidia,tegra20-kbc";
reg = <0x7000e200 0x100>;
interrupts = <0 85 0x04>;
clocks = <&tegra_car 36>;
resets = <&tegra_car 36>;
reset-names = "kbc";
nvidia,ghost-filter;
nvidia,debounce-delay-ms = <640>;
nvidia,kbc-row-pins = <0 1 2>; /* pin 0, 1, 2 as rows */
nvidia,kbc-col-pins = <11 12 13>; /* pin 11, 12, 13 as columns */
linux,keymap = <0x00000074
0x00010067
0x00020066
0x01010068
0x02000069
0x02010070
0x02020071>;
