MAX77620 supports 40, 80, 160, 320, 640, 1280, 2560 and 5120 microseconds.

-maxim,power-ok-control: configure map power ok bit
|
||||
1: Enables POK(Power OK) to control nRST_IO and GPIO1
|
||||
POK function.
|
||||
0: Disables POK control.
|
||||
if property missing, do not configure MPOK bit.
|
||||
If POK mapping is enabled for GPIO1/nRST_IO then,
|
||||
GPIO1/nRST_IO pins are HIGH only if all rails
|
||||
that have POK control enabled are HIGH.
|
||||
If any of the rails goes down(which are enabled for POK
|
||||
control) then, GPIO1/nRST_IO goes LOW.
|
||||
this property is valid for max20024 only.

|
