From c238eeebc91f60e0240f9ab7dff245a4621c5d7a Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 22 Dec 2020 19:30:25 -0700 Subject: [PATCH] x86: apl: Drop support for !OF_PLATDATA_PARENT This code was kept around after of-platdata started supporting parent devices. That feature seems stable now, so let's drop it.
