Out of which AVDD28 and VDDIO regulators are required in few goodix CTP chips during power-on sequence. AVDD22, DVDD12 regulators have no relevant functionality described from datasheet [1]. So, document both AVDD28, VDDIO regulators into optional properties since few of the goodix chip do work without these regulator power-on sequence.
