Since we don't switch to PMU.standby, on suspend we should not
be defining these.
Btw, this fixes the WSOD I observed on andy-tracking and also
gets rid of the regulator related backtrace seen upon resume.

Changes related to pcf50633_mfd.patch
|
|
pcf50633 driver rewritten to use the MFD model.
|
|
1. Removes pmu_voltage_rails stuff and replaces it with regulator_init_data[]
2. Removes voltage_ldoX and other /sys attributes.
3. Introduces s3c2410_pm_begin method to call regulator_suspend_prepare()
|
|
Specify regulator constraints for gta02. For now, constraints for only
the current used devices are specified.
|
|
Modify pcf50633 driver to use the new regulator API.
|
|
Use menuconfig instead of flat configs so that you can disable/enable
regulator items with one selection. Also, use depends instead of
reverse selections to make life easier, too.

Changes the device registration part of the probe function to supply the
regulator device rather than its parent (the mfd device) as this caused
problems when the regulator core attempted to find constraints associated
with the regulators.

The WM8350 features six DCDC convertors (four buck and two boost), four
LDO voltage regulators and two constant current sinks. This driver adds
support for these through the regulator API.
This driver was written by Liam Girdwood with updates for submission
from Mark Brown.

The WM8400 provides two programmable DCDC step-down (buck) convertors
and four low-dropout (LDO) regulators. This driver provides support for
runtime managment of these in the standard regulator API.
Support for configuration of the suspend and hibernate mode behaviour
of the regulators is not yet included.

This improves the machine level API in order to configure
regulator constraints and consumers as platform data and removes the
old string based API that required several calls to set up each regulator.
The intention is to create a struct regulator_init_data, populate
it's fields with constraints, consumers devices, etc and then register
the regulator device from board.c in the standard Linux way.
e.g. regulator LDO2 (supplying codec and sim) platform data.
/* regulator LDO2 consumer devices */
static struct regulator_consumer_supply ldo2_consumers[] = {
{
.dev = &platform_audio_device.dev,
.supply = "codec_avdd",
},
{
.dev = &platform_sim_device.dev,
.supply = "sim_vcc",
}
};
/* regulator LDO2 constraints */
static struct regulator_init_data ldo2_data = {
.constraints = {
.min_uV = 3300000,
.max_uV = 3300000,
.valid_modes_mask = REGULATOR_MODE_NORMAL,
.apply_uV = 1,
},
.num_consumer_supplies = ARRAY_SIZE(ldo2_consumers),
.consumer_supplies = ldo2_consumers,
};
/* machine regulator devices with thier consumers and constraints */
static struct platform_device wm8350_regulator_devices[] = {
{
.name = "wm8350-regulator",
.id = WM8350_LDO_2,
.dev = {
.platform_data = &ldo2_data,
},
},
};
Changes in detail:-
o Removed all const char* regulator config functions in machine API.
o Created new struct regulator_init_data to contain regulator
machine configuration constraints and consmuers.
o Changed set_supply(), set_machine_constraints(),
set_consumer_device_supply() to remove their string identifier
parameters. Also made them static and moved functions nearer top of
core.c.
o Removed no longer used inline func to_rdev()
o Added regulator_get_init_drvdata() to retrieve init data.
o Added struct device* as parameter to regulator_register().
o Changed my email address.

This adds the regulator framework core.
This framework is designed to provide a generic interface to voltage
and current regulators within the Linux kernel. It's intended to
provide voltage and current control to client or consumer drivers and
also provide status information to user space applications through a
sysfs interface.
The intention is to allow systems to dynamically control regulator
output in order to save power and prolong battery life. This applies
to both voltage regulators (where voltage output is controllable) and
current sinks (where current output is controllable).
This framework safely compiles out if not selected so that client
drivers can still be used in systems with no software controllable
regulators.
