Hello!
Please look at this code from drivers/i2c/i2c-gpio.c:
static int i2c_gpio_of_to_plat(struct udevice *dev)
{
struct i2c_gpio_bus *bus = dev_get_priv(dev);
int ret;
/* "gpios" is deprecated and replaced by "sda-gpios" + "scl-gpios". */
ret = gpio_request_list_by_name(dev, "gpios", bus->gpios,
ARRAY_SIZE(bus->gpios), 0);
if (ret == -ENOENT) {
The condition is always false because in
gpio_request_list_by_name_nodev(), if entry is not found, this code
will work:
if (ret == -ENOENT)
break;
and then
return count;
return zero.
