From 83c7e434c9dd3ca81f8b763e23c1881b973bcf2f Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 25 Jan 2015 08:27:10 -0700 Subject: dm: core: Allow uclass to set up a device's child before it is probed Some buses need to set up their devices before they can be used. This setup may well be common to all buses in a particular uclass. Support a common pre-probe method for the uclass, called before any bus devices are probed.
