Kernel driver w1-gpio | |
===================== | |
Author: Ville Syrjala <syrjala@sci.fi> | |
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); |
