Subject: [PATCH v1 5/5] clk: tegra: divider: Mark Memory Controller clock as read-only
Date: Fri, 12 Apr 2019 01:02:30 +0300 [thread overview]
Message-ID: <20190411220230.21726-6-digetx@gmail.com> (raw)
In-Reply-To: <20190411220230.21726-1-digetx@gmail.com>
The Memory Controller clock rate can't be simply changed and nothing in
kernel need to change the rate, hence let's make the clock read-only.
