Subject: Revert "arm64: Layerscape: Survive LPI one-way reset workaround"
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=a84cea06bb8fff69810a890ac0e4b47ea5726512;p=u-boot.git

Revert "arm64: Layerscape: Survive LPI one-way reset workaround"

Ad-hoc bindings that are not part of the upstream device tree / bindings
are not allowed in-tree.  Only bindings that are in-progress with
upstream and then re-synced once agreed upon are.

This reverts commit af288cb291da3abef6be0875527729296f7de7a0.
