| 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); |
