Revert "mfd: sec-core: Prepare regulators for suspend state to reduce power-consumption"

2014-11-25T16:18:47+00:00

This reverts commit b7cde7078d2344073c310aa65fc2b0a845d2cb5b
("mfd: sec-core: Prepare regulators for suspend state to reduce power-consumption")

Commit b7cde7078d23 called regulator_suspend_prepare() to prepare the
regulators for a suspend state. But it did from the device pm suspend
handler while the regulator suspend prepare function iterates over all
regulators and not only the one managed by this device so it doesn't
seems to be correct to call it from within a device driver.

It is better to call the regulator suspend prepare/finish functions
from platform code instead so this patch reverts the mentioned commit.

regulator: s2mps11: Add support S2MPS13 regulator device

2014-11-25T15:55:06+00:00

This patch adds S2MPS13 regulator device to existing S2MPS11 device driver.
The S2MPS13 has just different number of regulators from S2MPS14.
The S2MPS13 regulator device includes LDO[1-40] and BUCK[1-10].

mfd: sec-core: Add support for S2MPS13 device

2014-11-25T15:55:01+00:00

This patch adds the support for Samsung S2MPS13 PMIC device to the sec-core MFD
driver. The S2MPS13 is very similar with existing S2MPS14 and includes PMIC/
RTC/CLOCK devices.

mfd: sec-core: Fix IRQ handling after resume if this is not a wakeup source

2014-06-03T07:11:22+00:00

During suspend the IRQ should be disabled even if this is not a wakeup
source. This is a proper way of fixing the IRQ handling issue during
resume (IRQ handler fails because I2C bus did not resume yet).

When device is suspended and sec-core interrupt is signaled the irq chip
will try to handle it regardless of wakeup source. Device could be woken
up by different IRQ but still the IRQ handler will try to read the
registers over I2C bus and fail because I2C bus won't be ready yet.

mfd: sec-core: Remove duplicated device type from sec_pmic_dev

2014-06-03T07:11:21+00:00

The device type was stored in sec_pmic_dev state container twice:
 - unsigned long type (initialized from of_device_id or i2c_device_id)
 - int device_type (initialized as above or from board files when there
   is no DTS)

The 'type' field was never used outside of probe so it can be safely
removed.

Change also the device_type in sec_pmic_dev and sec_platform_data to
unsigned long to avoid any casts.
