I have two questions about PMIC_STBY_REQ pin driver.
It say that "PMIC_STBY_REQ is i.MX6 (actively driven) output. No need for pull up resistor, as for open drain signals."
But in document Table 2-6 of page 17 in Hardware Development Guide(IMX6DQ6SDLHDG.pdf),
It say that "PMIC_STBY_REQ – open-drain output." (without pull-up)
The other hand, PMIC_ON_REQ say that "open-drain output, on-chip 100 kOhm pull-up"
Old version of Hardware Development Guide(IMX6DQ6SDLHDG.pdf)
It say that PMIC_STBY_REQ – push-pull output.
In datasheet, it say only "output Low" as "Out of Reset Condition."
1) Which is a correct answer of PMIC_STBY_REQ pin driver model?
b. open-drain with internal pull-up
2) If it is open-drain output, which chip (i.MX6D or MMPF0100) pulls PMIC_STBY_REQ line to high?
