In an effort to give some love to the apparently forgotten MT6795 SoC,
I am upstreaming more components that are necessary to support platforms
powered by this one apart from a simple boot to serial console.
This series introduces support in the PMIC Wrapper for a different PMIC
topology, which is commonly found on smartphone boards, using one main
PMIC and one Companion/Sub PMIC, both accessible *only* through the pwrap;
be aware that this kind of topology is not *specific to* the Helio X10
SoC, but common across many kinds of MediaTek smartphone oriented SoCs
and board designs.
That said, support for the PMIC combo MT6331+MT6332 is provided in this
series in a form that will be able to initialize the PMICs with crypto
and DualIO but nothing else: these PMICs are very featureful, so I have
decided to add this support in more than just one step, as there will
be multiple patches for multiple different subsystems (..it's a mfd!..).
Tested on a MT6795 Sony Xperia M5 (codename "Holly") smartphone.
