[PATCH v1 1/6] dt-bindings: memory: tegra20: emc: Replace core regulator with power domain

From: Dmitry Osipenko
Date: Mon Mar 29 2021 - 15:47:48 EST


Power domain fits much better than a voltage regulator in regards to
a proper hardware description and from a software perspective as well.
Hence replace the core regulator with the power domain. Note that this
doesn't affect any existing DTBs because we haven't started to use the
regulator yet, and thus, it's okay to change it.
