From f5c67ea036be174f75cb48b8f91894bc710811dd Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 30 Jul 2015 13:40:39 -0600 Subject: dm: core: Add a way to set a device name Some devices are bound entirely by probing and do not have the benefit of a device tree to give them a name. This is very common with PCI and USB. In most cases this is fine, but we should add an official way to set a device name. This should be called in the device's bind() method.
