Hello, Couple years ago the Tegra20 EMC driver was removed from the kernel due to incompatible changes in the Tegra's clock driver. This patchset introduces a modernized EMC driver. Currently the sole purpose of the driver is to initialize DRAM frequency to maximum rate during of the kernels boot-up. Later we may consider implementing dynamic memory frequency scaling, utilizing functionality provided by this driver.
