Subject: [PATCH v1 1/2] memory: tegra20: Correct comment to MC_STAT registers writes
Date: Wed, 24 Mar 2021 00:04:45 +0300 [thread overview]
Message-ID: <20210323210446.24867-1-digetx@gmail.com> (raw)
The code was changed multiple times and the comment to MC_STAT
registers writes became slightly outdated. The MC_STAT programming
now isn't hardcoded to the "bandwidth" mode, let's clarify this in
the comment.
