This is third iteration of my patch series adding ASV (Adaptive Supply Voltage) support for Exynos SoCs. The previous one can be found at: https://lore.kernel.org/lkml/20190718143044.25066-1-s.nawrocki@xxxxxxxxxxx There is no major changes in this series comparing to v2, only minor corrections addressing review comments. I was not sure it was a good idea to try to extend the OPP binding so as to include the ASV data tables in DT, so the tables are left in the driver. This patch set includes Exynos CHIPID driver posted by Pankaj Dubey and futher improved by Bartłomiej Żołnierkiewicz [1]. Tested on Odroid XU3, XU3 Lite, XU4. One of the things on TODO list is support for the Adaptive Body Bias. This will require modifications on the cpufreq driver side in order to support multiple voltage regulators and changes in the OPP framework to support adding OPPs with multiple voltages.
