Subject: [PATCH v5 0/8] Add EMC scaling support for Tegra210
Date: Tue, 10 Mar 2020 16:19:55 +0100 [thread overview]
Message-ID: <20200310152003.2945170-1-thierry.reding@gmail.com> (raw)
From: Thierry Reding <treding@nvidia.com>
This series introduces the EMC clock scaling support for Tegra210. The
EMC table of supported frequencies is passed to the kernel via a device
tree reserved memory region.
Joseph posted the v4 of this series[0] about a year ago. I've dusted it
off a bit and tried to address all of the comments that Dmitry had made
in response to v4.
Changes in v4:
- major rework to split this into a clk driver and an EMC driver
- refactored some code to remove duplication and improve readability
- removed some unused code and variables
