Subject: [PATCH v2 15/22] memory: tegra20-emc: Create tegra20-devfreq device
Date: Mon, 30 Mar 2020 04:08:57 +0300 [thread overview]
Message-ID: <20200330010904.27643-16-digetx@gmail.com> (raw)
In-Reply-To: <20200330010904.27643-1-digetx@gmail.com>
The tegra20-devfreq driver provides memory frequency scaling functionality
and it uses EMC clock for the scaling. Since tegra20-devfreq is a software
driver, the device for the driver needs to be created manually. Let's do
it from EMC driver since it provides the clk rate-change functionality.
