From bb58503d80808b973950ca425c7fb0bc6172a2bd Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 23 Jul 2014 06:55:23 -0600 Subject: dm: Add dm_scan_other() to locate board-specific devices Some boards will have devices which are not in the device tree and do not have platform data. They may be programnatically created, for example. Add a hook which boards can use to bind those devices early in boot.
