From 9bd5773e02d174dfab3c336fc43d18ec15afc5a3 Mon Sep 17 00:00:00 2001 From: Dmitry Osipenko Date: Thu, 3 Dec 2020 22:24:30 +0300 Subject: dt-bindings: memory: tegra20-emc: Document opp-supported-hw property Document opp-supported-hw property, which is not strictly necessary to have on Tegra20, but it's very convenient to have because all other SoC core devices will use hardware versioning, and thus, it's good to maintain the consistency.
