The series enables DVFS for the CPU cores (aka cpufreq) on the Allwinner H5 SoC. The OPP table was taken from Armbian, with minor tweaks to the maximum voltage to account for slightly increased voltage on some of the boards. In this version, the OPP table and tie in to the CPU cores has been split out into a separate file, like what was done for the H6. The patches adding CPU regulator supplies for all the boards that I don't have have been removed. The series now only enables cpufreq for Libre Computer ALL-H3-CC and ALL-H5-CC, and Bananapi M2+ v1.2. For the original Bananapi M2+, if I add the fixed regulator with the enable pin, it ends up causing some sort of glitch or lock up on the v1.2, which includes the original dts file. Since I haven't been able to sort it out yet, I've left it out for now. Patch 1 assigns the CPU regulator supply to all the CPU cores on the Libre Computer ALL-H3-CC. Patch 2 assigns the CPU regulator supply to all the CPU cores on the Bananapi M2+ v1.2. Patch 3 fixes the voltages specified for the GPIO-controlled regulator on the Bananapi M2+ v1.2. The voltages are slightly higher than what was originally written. Patch 4 ties the CPU clock to the CPU cores. Patch 5 adds trip points and cooling maps to the CPU thermal zones. Patch 6 adds the OPP table, based on the one from Armbian. Patch 7 hooks up the CPU regulator supply for the Libre Computer ALL-H3-CC H5 variant, and by extension, the ALL-H5-CC. Patch 8 hooks up the CPU regulator supply for the Bananapi M2+ v1.2. Changes since v1: - Re-ordered patches - Added patches to set regulator supply for all CPU cores - Added thermal trip points and cooling maps - OPP table and assignment split into separate file - Added patches to tie in OPP table file for the boards I have Please have a look.
