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. This has been tested on the Bananapi M2+ v1.2 and Libre Computer ALL-H3-CC H5 ver.. I do not have the remaining boards so I've CC-ed people who did the original submission or have modified the board specifically later on. Patch 1 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 2 adds a fixed regulator for the CPU on the original Bananapi M2+. This is for the retail version, not the engineering samples that had an even higher voltage setting. Patch 3 hooks up the CPU regulator supply for H5 boards that already define the regulator, but were missing the property to tie it to the CPUs. Patch 4 ~ 8 adds the CPU regulator for boards that don't have it defined. This is based on each vendor's schematics. I need people to test each of these specifically and the whole series. Patch 9 ties the CPU clock to the CPU cores. Patch 10 adds the OPP table, based on the one from Armbian. Please have a look and please help test this.
