Hello Doug,
Thanks a lot for your feedback.

Some max77802 LDOs (1, 3, 20 and 21) support to be configured in Low
Power Mode during system normal operation. Add function handlers for
the .get_mode and .set_mode operations to set the mode on these LDOs.

Not all the max77802 BUCKs regulators have the same functionality, for
example BUCKs 2-4 support the output to be configured as normal or Low
Power Mode by the PWRREQ enable pin while the other BUCKs only support
their output to be set ON or OFF by PWRREQ. As a preparation for adding

Hello Mark,
This is the second attempt to add operating modes support for the
regulators in the max77802 PMIC. Instead of trying to come up with
a generic solution like in the previous attempt [0], I added DT
properties that are specific to the max77802 PMIC so is documented
clearly what are the o
The max77802 PMIC has an enable pin (PWRREQ) that can be used to switch
regulators ON and OFF automatically by the Application Processor when
the system is leaving and entering sleep mode.
Only the BUCKs regulators had a .set_suspend_disable function handler
that used the enable pin to turn OFF th
The only operating modes that are supported by the regulators in the
max77802 PMIC are Output ON (normal) and Output On in Low Power Mode.
OFF was wrongly counted as an operating mode while is only a regulator
status. Make clear in the code that OFF is not an operating mode.

The max77802 PMIC has a special enable pin (PWRREQ) that can be used
by the Application Processor (AP) to power down and up voltage rails.
The max77802 PMIC regulators have 3 different enable control logics.
Some regulators support to be configured on different operational mode
during normal opera
Add a header file for the max77802 constants that could be shared between
the regulator driver and Device Tree source files. Also, remove standby
and off opmodes since only normal and low power are valid operating modes.

Some regulators from the max77802 PMIC support to be configured in one
of two operating mode: Output ON (normal) and Output On Low Power Mode.
Not all regulators support these two modes and for some of them, the
mode can be changed while the system is running in normal operation
while others only s
The regulator core now has support to choose if a regulator
has to be enabled or disabled during system suspend and also
the max77802 driver supports changing the regulator operating
mode during runtime and when the system enters into sleep mode.
To lower power during suspend, configure the regula
The max77802 PMIC regulators output can be configured in one of two
modes: Output ON (normal) and Output ON in Low Power Mode. Some of
the regulators support their operating mode to be changed on startup
or by consumers when the system is running while others only support
their operating mode to be

The regulator framework has a set of helpers functions to be used when
the system is entering and leaving from suspend but these are not called
on Exynos platforms. This means that the .set_suspend_* function handlers
defined in regulator drivers are never called when the system is suspended.
