Hello,
This series add support for Exynos platforms to prepare regulators for
system suspend. The regulator core has a set of helpers functions to be
used when the system is entering and leaving from a suspend state but
currently there is only one user in mainline.
This user is
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 by regulator drivers are not called when the system is suspended.
Hello Mark,
Thanks a lot for your feedback.

This patch changes s3c_hsotg_core_init function to leave hardware in
soft disconnect mode, so the actual moment of coupling the hardware to
the usb bus can be later controlled by the driver in the more accurate
way. For this purpose, separate functions for enabling and disabling
soft disconnect
This patch fixes probe function to match the pattern used elsewhere in
the driver, where power regulators are turned off as the last element in
the device shutdown procedure.

Excessive debug messages might cause timing issues that prevent correct
usb enumeration. This patch hides information about USB bus reset to let
driver enumerate fast enough to avoid making host angry. This fixes
endless enumeration and usb reset loop observed with some Linux hosts.
This patch removes duplicated code and sets last_rst variable in the
function which does the hardware reset.

Suspend/resume code assumed that the gadget was always enabled and
connected to usb bus. This means that the actual state of the gadget
(soft-enabled/disabled or connected/disconnected) was not correctly
preserved on suspend/resume cycle. This patch fixes this issue.

Hi,
your subject line is wrong. -pullup() is already implemented, you're
moving unnecessary code from -pullup() to other places.

Hello Mark,
This is the second version of the series that adds operating modes
support for the regulators in the max77802 PMIC. It address issues
pointed out in regulator: max77802: Add .{get,set}_mode callbacks
and also removes the patches you already picked on the topic branch.
The first
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
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
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.
