The Toshiba TC3589x series are I2C-based MFD devices which may expose the
following built-in devices: gpio, keypad, rotator (vibrator), PWM (for
e.g. LEDs or vibrators) The included models are:
Required properties:
- compatible : must be "toshiba,tc35890", "toshiba,tc35892", "toshiba,tc35893",
"toshiba,tc35894", "toshiba,tc35895" or "toshiba,tc35896"
- reg : I2C address of the device
- interrupts : the interrupt on the parent the controller is connected to
- interrupt-controller : marks the device node as an interrupt controller
- #interrupt-cells : should be <1>, the first cell is the IRQ offset on this
TC3589x interrupt controller.
Optional nodes:
- GPIO
This GPIO module inside the TC3589x has 24 (TC35890, TC35892) or 20
(other models) GPIO lines.
- compatible : must be "toshiba,tc3589x-gpio"
- interrupts : interrupt on the parent, which must be the tc3589x MFD device
- interrupt-controller : marks the device node as an interrupt controller
- #interrupt-cells : should be <2>, the first cell is the IRQ offset on this
TC3589x GPIO interrupt controller, the second cell is the interrupt flags
in accordance with <dt-bindings/interrupt-controller/irq.h>. The following
flags are valid:
- IRQ_TYPE_LEVEL_LOW
- IRQ_TYPE_LEVEL_HIGH
- IRQ_TYPE_EDGE_RISING
- IRQ_TYPE_EDGE_FALLING
- IRQ_TYPE_EDGE_BOTH
- gpio-controller : marks the device node as a GPIO controller
- #gpio-cells : should be <2>, the first cell is the GPIO offset on this
GPIO controller, the second cell is the flags.
- Keypad
This keypad is the same on all variants, supporting up to 96 different
keys. The linux-specific properties are modeled on those already existing
in other input drivers.
- compatible : must be "toshiba,tc3589x-keypad"
- debounce-delay-ms : debounce interval in milliseconds
- keypad,num-rows : number of rows in the matrix, see
bindings/input/matrix-keymap.txt
- keypad,num-columns : number of columns in the matrix, see
bindings/input/matrix-keymap.txt
- linux,keymap: the definition can be found in
bindings/input/matrix-keymap.txt
- linux,no-autorepeat: do no enable autorepeat feature.
- wakeup-source: use any event on keypad as wakeup event.
(Legacy property supported: "linux,wakeup")
