drivers/regulator: include for modular max77802 code

2015-06-16T18:12:26+00:00

This file is built off of a tristate Kconfig option and also contains
modular function calls so it should explicitly include module.h to
avoid compile breakage during header shuffles done in the future.

Merge tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2014-12-15T00:10:09+00:00

Pull driver core update from Greg KH:
 "Here's the set of driver core patches for 3.19-rc1.

  They are dominated by the removal of the .owner field in platform
  drivers.  They touch a lot of files, but they are "simple" changes,
  just removing a line in a structure.

  Other than that, a few minor driver core and debugfs changes.  There
  are some ath9k patches coming in through this tree that have been
  acked by the wireless maintainers as they relied on the debugfs
  changes.

  Everything has been in linux-next for a while"

regulator: max77802: Remove support for board files

2014-11-26T20:38:32+00:00

The driver is used only on Exynos based boards with DTS support.
Simplify the driver and remove dead (unused) entries in platform_data
structure.

Convert the driver to DTS-only version. Parse all regulators at once,
not one-by-one. Remove dependency on data provided by max77686 MFD
driver. Use new DT style parsing method for regulators init data.

regulator: max77802: Fill regulator modes translation callback

2014-11-26T19:42:47+00:00

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 changed while the system has entered in a
suspend state.

Use the max77802_map_mode() function to translate the device specific
modes to the standard operating modes as used by the regulator core.

regulator: max77802: Don't ignore return value of current opmode

2014-11-04T20:47:50+00:00

The return value of regmap_read() of current opmode for regulator was
silently ignored and whatever happened to be in 'val' variable was used
as new opmode. This could lead to using bogus opmode.

Don't ignore what regmap_read() returns. If it fails just fall back to
normal opmode.

regulator: max77802: Use unsigned int for modes in max77802_map_mode()

2014-11-03T16:08:21+00:00

All function dealing with operating modes use unsigned int for modes
so change max77802_map_mode() function signature for consistency.

regulator: max77802: zero-initialize regulator match table

2014-11-03T15:55:27+00:00

The struct of_regulator_match is declared as a non-static local variable
so the structure members are not auto-initialized.

Initialize the struct at declaration time to avoid the structure members
values to be indeterminate and have sane defaults instead.

regulator: max77802: Remove suspend_enable

2014-10-31T12:34:16+00:00

The Maxim 77802 PMIC regulators do not have special enable configuration
for suspend. The driver instead enabled them manually which is not a
best way to deal with suspend.
