static struct pinctrl *create_pinctrl(struct device *dev)
{
struct pinctrl *p;
const char *devname;
struct pinctrl_maps *maps_node;
int i;
struct pinctrl_map const *map;
int ret;
/*
* create the state cookie holder struct pinctrl for each
* mapping, this is what consumers will get when requesting
* a pin control handle with pinctrl_get()
*/
p = kzalloc(sizeof(*p), GFP_KERNEL);
if (p == NULL) {
dev_err(dev, "failed to alloc struct pinctrl\n");
return ERR_PTR(-ENOMEM);
}
p->dev = dev;
INIT_LIST_HEAD(&p->states);
INIT_LIST_HEAD(&p->dt_maps);
printk("---->create_pinctrl:%s\n",dev_name(dev)); //add this
ret = pinctrl_dt_to_map(p);
if (ret < 0) {
kfree(p);
return ERR_PTR(ret);
}
