- 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);
