PMIC PM8008 LDOs do not support low power mode (LPM). PMIC PM8010 PMOS LDOs (i.e. LDOs 3-7) do not support LPM. If configured for LPM, these LDOs continue to operate in normal power mode (NPM) with the same quiescent current. However, their over-current protection (OCP) threshold is significantly reduced, well below their rated output current. This can result in OCP triggering and unexpectedly disabling an LDO that is configured for LPM. Since LPM is not supported, using it leads to no power efficiency improvements, and using it can cause false-positive OCP triggering, disallow mode control for all PM8008 LDOs and PM8010 LDOs 3-7. Rely on the hardware default NPM configuration for these LDOs instead. Change-Id: I7f68e364b5b7cb6fe23d3ac0976a7993b4d83621
