Description
|
|
-----------
|
|
|
|
GPIO 1-wire bus master driver. The driver uses the GPIO API to control the
|
|
wire and the GPIO pin can be specified using platform data.
|
|
|
|
|
|
Example (mach-at91)
|
|
-------------------
|
|
|
|
#include <linux/w1-gpio.h>
|
|
|
|
static struct w1_gpio_platform_data foo_w1_gpio_pdata = {
|
|
.pin = AT91_PIN_PB20,
|
|
.is_open_drain = 1,
|
|
};
|
|
|
|
static struct platform_device foo_w1_device = {
|
|
.name = "w1-gpio",
|
|
.id = -1,
|
|
.dev.platform_data = &foo_w1_gpio_pdata,
|
|
};
|
|
|
|
...
|
|
at91_set_GPIO_periph(foo_w1_gpio_pdata.pin, 1);
|
|
at91_set_multi_drive(foo_w1_gpio_pdata.pin, 1);
|
|
platform_device_register(&foo_w1_device);
