From 426f99fa98c3725fe0ca1eb8438d1215a2c6bd6b Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 24 Apr 2017 09:48:02 +0200 Subject: dm: core: Add DM_FLAG_OS_PREPARE flag This new flag can be added to DM device drivers, which need to do some final configuration before U-Boot exits and the OS (e.g. Linux) is started. The remove functions of those drivers will get called at this stage to do these last-stage configuration steps.
