Subject: [PATCH v1 0/4] Tegra20 External Memory Controller driver
Date: Wed, 30 May 2018 18:06:42 +0300 [thread overview]
Message-ID: <20180530150646.19030-1-digetx@gmail.com> (raw)
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.
Dmitry Osipenko (4):
dt: bindings: tegra20-emc: Document interrupt property
ARM: dts: tegra20: Add interrupt to External Memory Controller
clk: tegra20: Turn EMC clock gate into divider
memory: tegra: Introduce Tegra20 EMC driver
