The HP_EINT is an external, not internal, pin of the MT6359 PMIC. It is an input pin of the MT6359 IC that gets wired to the tip (left channel) of a 3.5mm audio jack to allow for detecting when a plug is connected. Since this dt-binding is about an IP in the MT6359 PMIC, I think when saying "HP_EINT pin" it is already clear that the pin is on the MT6359 IC, but if you think it's necessary I could make it "MT6359's HP_EINT pin". Thanks, Nícolas

"MT6359's HP_EINT pin" looks good to me, btw. Cheers! Angelo
