Currently I am working on the PWM driver to complete .get_state() support. This allowed me to read the VDDEE voltage set by u-boot on my Meson8b boards (EC-100 and Odroid-C1). VDDEE supplies the Mali GPU.
It turns out that the bootloader configures a VDDEE voltage of 1.10V instead of 1.15V. 1.15V is actually out-of-range for that regulator design. This is meant to be applied on top of my other GPU fixes from [0] also targetting v5.2 if possible.
