Hi all, The Allwinner A83T is an octacore A7 divided in two clusters of 4 A7, each cluster having its own regulator and clock. Let's add the OPPs for each cluster so that we can use cpufreq on this SoC. The operating points were found in Allwinner BSP and fex files and have been tested on a TBS A711 with cpuburn and cpufreq-ljt-stress-test. Note that there are a few OPPs that are missing: 1608000000Hz with 920000mV 1800000000Hz with 1000000mV 2016000000Hz with 1080000mV These OPPs are pretty unstable but it might be due to the SoC quickly overheating (till the board completely shuts down). It seems[1] impossible to reach those frequencies with none or passive cooling, so better leave them out by default. It's still possible to add those OPPs on a per-board basis though.
