I have done this:
struct device_node *node = dev->of_node;
struct device_node *node2;
node2 = of_get_child_by_name(node, "multi");
printk("node2 %pOF %pfw %x\n", node2, node2->fwnode, node2->fwnode.flags);
node2->fwnode.flags |= FWNODE_FLAG_NOT_DEVICE;
of_node_put(node2);
This doesn't do anything, but this does:
struct device_node *node = dev->of_node;
struct device_node *node2;
node2 = of_get_child_by_name(node, "multi");
fw_devlink_purge_absent_suppliers(&node2->fwnode);
printk("node2 %pOF %pfw %x\n", node2, node2->fwnode, node2->fwnode.flags);
of_node_put(node2);
Should I be using fw_devlink_purge_absent_suppliers?
