Changes in v3: - Rebased on next-20230412 - Changed if branch to switch in pwrap_init() as suggested by Matthias and Alexandre.
Changes in v2: - Rebased on next-20230323 - Changed pwrap.txt addition to new yaml file addition
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.
