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.
