This patch marks all the reference to the legacy wakeup bindings and replaces them with the standard "wakeup-source" property. All these legacy property are also listed under a separate section in the generic wakeup-source binding document.

* Toshiba TC3589x multi-purpose expander
|
|
|
|
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:
|
|
|
|
- TC35890
|
|
- TC35892
|
|
- TC35893
|
|
- TC35894
|
|
- TC35895
|
|
- TC35896
|
|
|
|
Required properties:
|
|
- compatible : must be "toshiba,tc35890", "toshiba,tc35892", "toshiba,tc35893",
|
|
"toshiba,tc35894", "toshiba,tc35895" or "toshiba,tc35896"
|
|
- reg : I2C address of the device
|
|
- interrupt-parent : specifies which IRQ controller we're connected to
|
|
- 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")
