uclass name is used by dev_read_alias_seq which return seq number when aliases are used.
Code fragment: 168 int dev_read_alias_seq(struct udevice *dev, int *devnump) 169 { 170 ofnode node = dev_ofnode(dev); 171 const char *uc_name = dev->uclass->uc_drv->name; 172 int ret; 173 174 if (ofnode_is_np(node)) { 175 ret = of_alias_get_id(ofnode_to_np(node), uc_name);
Also this patch enables DM_UC_FLAG_SEQ_ALIAS to be in sync with Linux which is also using watchdog name for watchdog aliases.
drivers/watchdog/watchdog_core.c:215: ret = of_alias_get_id(wdd->parent->of_node, "watchdog");
