Adds a number of missing device tree properties for twl4030/gpio, and update bindings: - "ti,use-leds" -> .use_leds - "ti,debounce" -> .debounce - "ti,mmc-cd" -> .mmc_cd - "ti,pullups" -> .pullups - "ti,pulldowns" -> .pulldowns Signed-off-by: Florian Vaussard <florian.vaussard@epfl.ch> Acked-by: Linus Walleij <linus.walleij@linaro.org> Acked-by: Vaibhav Hiremath <hvaibhav@ti.com> [b-cousson@ti.com: Fix some checkpatch CHECK issues] Signed-off-by: Benoit Cousson <b-cousson@ti.com>

twl4030 GPIO controller bindings
|
|
|
|
Required properties:
|
|
- compatible:
|
|
- "ti,twl4030-gpio" for twl4030 GPIO controller
|
|
- #gpio-cells : Should be two.
|
|
- first cell is the pin number
|
|
- second cell is used to specify optional parameters (unused)
|
|
- gpio-controller : Marks the device node as a GPIO controller.
|
|
- #interrupt-cells : Should be 2.
|
|
- interrupt-controller: Mark the device node as an interrupt controller
|
|
The first cell is the GPIO number.
|
|
The second cell is not used.
|
|
- ti,use-leds : Enables LEDA and LEDB outputs if set
|
|
- ti,debounce : if n-th bit is set, debounces GPIO-n
|
|
- ti,mmc-cd : if n-th bit is set, GPIO-n controls VMMC(n+1)
|
|
- ti,pullups : if n-th bit is set, set a pullup on GPIO-n
|
|
- ti,pulldowns : if n-th bit is set, set a pulldown on GPIO-n
|
|
|
|
Example:
|
|
|
|
twl_gpio: gpio {
|
|
compatible = "ti,twl4030-gpio";
|
|
#gpio-cells = <2>;
|
|
gpio-controller;
|
|
#interrupt-cells = <2>;
|
|
interrupt-controller;
|
|
ti,use-leds;
|
|
};
