Subject: [PATCH v1 0/3] memory: Introduce NVIDIA Tegra30 EMC driver
Date: Fri, 12 Apr 2019 02:02:18 +0300 [thread overview]
Message-ID: <20190411230221.31362-1-digetx@gmail.com> (raw)
Hello,
This patchset adds driver for the External Memory Controller of NVIDIA
Tegra30 SoC's. It performs memory hardware configuration that is required
for changing DRAM frequency, thus providing facility for the memory
frequency scaling on Tegra30. The memory scaling was tested using the
Tegra's devfreq driver which is available in upstream, it dynamically
changes memory clock rate based on memory clients activity.
