From bb44ebdd0f3eccece2081ec51cf3b3554dafd801 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 3 Oct 2020 11:31:39 -0600 Subject: [PATCH] x86: apl: Take advantage of the of-platdata parent support Now that parent devices are supported with of-platadata, we don't need the messy code to fix up the parent pointers and allocations on Apollo Lake. Put the code behind a condition.
