Is there a method to power up the i.MX8 from an off condition with the internal time of day clock?
This same question was asked about the i.MX6 ( https://www.spinics.net/lists/arm-kernel/msg561152.html ) in february of 2017, there seemed to be a couple kernel bugs preventing the correct behavior but if i read the answers posted it was yes. The i.MX8 register structure is very similar.
Figure 6-32 in the reference manual suggests there are events from the SNVS domain that can activate PMIC_ON_REQ just like the on/off button. Unable to find clarity in the documentation if time of day clock is one of these. HPRTC cannot - Time Of Day clock is always running however.
