- #gpio-cells: Should be two. The first cell is the pin number and
the second cell is used to specify flags.
See ../gpio/gpio.txt for more information.
- xxx-in-supply: Phandle to parent supply node of each regulator
populated under regulators node. xxx can be
buck0, buck1, ldo0 or ldo1.
- regulators: List of child nodes that specify the regulator
initialization data.

@ -106,6 +106,18 @@ Here supported time periods by device in microseconds are as follows:
MAX77620 supports 40, 80, 160, 320, 640, 1280, 2560 and 5120 microseconds.
MAX20024 supports 20, 40, 80, 160, 320, 640, 1280 and 2540 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.
For DT binding details of different sub modules like GPIO, pincontrol,
regulator, power, please refer respective device-tree binding document
under their respective sub-system directories.
