Display regulators (AB/IBB/AMOLEDB, not to be confused with LAB/IBB) on modern Qualcomm platforms are controlled by the secure firmware layer (yes, you read that correctly). Some panels require additional supplies, but this one just has one positive, one negative and one I/O regulator. Konrad > > Rob ^ permalink raw reply [flat|nested] 9+ messages in thread
