[PATCH v2 0/5] MediaTek MT6357/8/9 PMIC Auxiliary ADC support

[AngeloGioacchino Del Regno]

Changes in v2:
 - Dropped 'mfd: mt6397-core: Add support for AUXADCs on MT6357/58/59 PMICs'
   as Lee J already applied it;
 - Added patch to describe the ADC subnode in the MT6357 MFD binding
   and moved the example node from mediatek,mt6359-auxadc.yaml to
   mediatek,mt6357.yaml
 - Added 8-bits {s8,u8}_fract to math.h
 - Addressed reviewer comments on mt6359-auxadc driver
