From 282ed24fb3ca8ddb37e9fb465452267e6a658233 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Mon, 16 Sep 2019 18:41:42 +0200 Subject: [PATCH] dm: MIGRATION: Add migration plan for CONFIG_DM For many sub-systems we already require the driver model to be used. Yet there is still a handful of boards that do not have CONFIG_DM enabled. We should make CONFIG_DM compulsory with release v2020.01 Conversion dates for CONFIG_DM_SPL and CONFIG_DM_TPL are yet to be defined.
