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");
