From 0118ce79577f9b0881f99a6e4f8a79cd5014cb87 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 25 Jan 2015 08:27:03 -0700 Subject: dm: core: Add a post_bind method for parents Allow parent drivers to be called when a new child is bound to them. This allows a bus to set up information it needs for that child.
