1 * Toshiba TC3589x multi-purpose expander
3 The Toshiba TC3589x series are I2C-based MFD devices which may expose the
4 following built-in devices: gpio, keypad, rotator (vibrator), PWM (for
5 e.g. LEDs or vibrators) The included models are:
15 - compatible : must be "toshiba,tc35890", "toshiba,tc35892", "toshiba,tc35893",
16 "toshiba,tc35894", "toshiba,tc35895" or "toshiba,tc35896"
17 - reg : I2C address of the device
18 - interrupts : the interrupt on the parent the controller is connected to
19 - interrupt-controller : marks the device node as an interrupt controller
20 - #interrupt-cells : should be <1>, the first cell is the IRQ offset on this
21 TC3589x interrupt controller.
26 This GPIO module inside the TC3589x has 24 (TC35890, TC35892) or 20
27 (other models) GPIO lines.
28 - compatible : must be "toshiba,tc3589x-gpio"
29 - interrupts : interrupt on the parent, which must be the tc3589x MFD device
30 - interrupt-controller : marks the device node as an interrupt controller
31 - #interrupt-cells : should be <2>, the first cell is the IRQ offset on this
32 TC3589x GPIO interrupt controller, the second cell is the interrupt flags
33 in accordance with <dt-bindings/interrupt-controller/irq.h>. The following
37 - IRQ_TYPE_EDGE_RISING
38 - IRQ_TYPE_EDGE_FALLING
40 - gpio-controller : marks the device node as a GPIO controller
41 - #gpio-cells : should be <2>, the first cell is the GPIO offset on this
42 GPIO controller, the second cell is the flags.
45 This keypad is the same on all variants, supporting up to 96 different
46 keys. The linux-specific properties are modeled on those already existing
47 in other input drivers.
48 - compatible : must be "toshiba,tc3589x-keypad"
49 - debounce-delay-ms : debounce interval in milliseconds
50 - keypad,num-rows : number of rows in the matrix, see
51 bindings/input/matrix-keymap.txt
52 - keypad,num-columns : number of columns in the matrix, see
53 bindings/input/matrix-keymap.txt
54 - linux,keymap: the definition can be found in
55 bindings/input/matrix-keymap.txt
56 - linux,no-autorepeat: do no enable autorepeat feature.
57 - wakeup-source: use any event on keypad as wakeup event.
