davids5 opened a new pull request, #8456:
URL: https://github.com/apache/nuttx/pull/8456
## Summary
Allows creation simple of the GPIO devices by pin name
For Example:
```
/****************************************************************************
* Private Types
****************************************************************************/
struct myboard_gpio_dev_s {
struct gpio_dev_s dev;
uint32_t pincfg;
pin_interrupt_t callback;
};
...
/****************************************************************************
* Name: myboard_gpio_register
*
* Description:
* Initialize GPIO driver for input pin.
*
* Input Parameters:
* pincfg - The pin configuration mask for the IO pin.
* pintype - The pin type
* devname - The name of the GPIO device path to register the IO pin as.
*
****************************************************************************/
int myboard_gpio_register(uint32_t pincfg, enum gpio_pintype_e pintype,
const char *devname)
{
FAR struct myboard_gpio_dev_s *priv;
priv = (myboard_gpio_dev_s *) kmm_zalloc(sizeof(struct
myboard_gpio_dev_s));
if (priv == NULL) {
gpioerr("Failed to allocate myboard_gpio_dev_s struct ERRNO:
%d\n", errno);
return -1;
}
priv->dev.gp_pintype = pintype;
priv->dev.gp_ops = &myboard_gpio_ops;
priv->pincfg = pincfg;
return gpio_pin_register_byname(&priv->dev, devname);
}
/****************************************************************************
* Public Functions
****************************************************************************/
void myboard_gpio_init(void)
{
(void)myboard_gpio_register(GPIO_nLED_RED, GPIO_OUTPUT_PIN,
"nLED_RED");
(void)myboard_gpio_register(GPIO_nLED_GREEN, GPIO_OUTPUT_PIN,
"nLED_GREEN");
(void)myboard_gpio_register(GPIO_nLED_BLUE, GPIO_OUTPUT_PIN,
"nLED_BLUE");
}
```
## Impact
None - New Method
