module provides ELVDD/ELVSS voltage rail output to power up AMOLED panels.
For PM8150A, allowed voltage levels are as below:
AVDD - Programmable output from 4.925 V to 8.1 V.
ELVDD - Programmable output from 4.6 V to 6.1 V.
AVDD - Programmable output from 5 V to 8 V.
ELVDD - Programmable output from 4.6 V to 5.2 V.
ELVSS - Programmable output from -0.8 V to -5.4 V.
For PM8350B, allowed voltage levels are as below:
AVDD - Programmable output from 5 V to 8 V.
ELVDD - Programmable output from 4.6 V to 5.2 V.
ELVSS - Programmable output from -1.4 V to -6.6 V.
This document describes the bindings for AMOLED regulator devices.
