The MT6359P is a eco version for MT6359 regulator. For the MT8391 platform, we use the MT6359P (MT6365) as the main PMIC. The MT6359 and MT6359P have different register maps. Therefore, on the MT8391 platform, we only provide support for the MT6359P. If support for the MT6359 PMIC it can be added later.

This also allows multiple variants to be supported by the same driver. Define a struct sec_regulator_desc which holds all values required by a regulator. Create an array of said struct containing all regulators. The descriptors are designed to follow a style similar to what's seen in the Linux driver, so comparing one with the other is simple. In functions such as s2mps11_{buck,ldo}_{val,mode} these values are to be used, make necessary modifications to pull them from the descriptors. Since multiple variants have varying descriptors, select them from within a switch-case block. Functions s2mps11_{buck,ldo}_{volt2hex,hex2volt} and arrays s2mps11_buck_{ctrl,out} are phased out as the calculations are now hardcoded in descriptors, thusly, it reduces clutter and enhances readability.
