From ea14778d0680f8a3f262a06ceb52ea17deb6a104 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 25 Sep 2019 08:55:53 -0600 Subject: [PATCH] dm: core: Call ofdata_to_platdata() with of-platdata At present this function is never called when of-platdata is enabled since we never have a device tree. However, this function is responsible for copying over the of-platdata, so we must call it. Otherwise the probe() method would have to be used. Correct this and fix the sandbox serial driver to not read from the device tree and try to write to what is read-only platdata on some platforms.
