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

2014-07-09T13:58:12+00:00

This patch use regulator_suspend_prepare() function to prepare the proper state
of regulators for suspend state to remove un-necessary leakage power-consumption.

regulator: s2mps11: Add support S2MPU02 regulator device

2014-07-09T13:58:11+00:00

This patch add S2MPU02 regulator device to existing S2MPS11 device driver
because of little difference between S2MPS1x and S2MPU02. The S2MPU02
regulator device includes LDO[1-28] and BUCK[1-7].

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.

mfd/rtc: s5m: Do not allocate RTC I2C dummy and regmap for unsupported chipsets

2014-06-03T07:11:16+00:00

The rtc-s5m driver does not support all of S2M and S5M chipsets
supported by main MFD sec-core driver. For such chipsets unsupported by
rtc-s5m, the MFD sec-core driver initialized regmap with default config.
This config in such cases wouldn't work at all.

The main MFD sec-core driver shouldn't initialize regmap for child
drivers which is not used by them and even not valid.

Move the allocation of RTC I2C dummy device and initialization of RTC
regmap from main MFD sec-core driver to the rtc-s5m driver. The rtc-s5m
driver will use proper regmap config for supported devices.

mfd: sec-core: Fix uninitialized 'regmap_rtc' on S2MPA01

2014-03-20T15:57:23+00:00

Initialize the 'regmap_rtc' on S2MPA01 to some sane value. Sane at least
for S5M87X chipsets, not S2MPS/S2MPA but it won't be used because
rtc-s5m driver does not support S2MPA01.

This fixes following error:
drivers/mfd/sec-core.c:342:45: warning: ‘regmap_rtc’ may be used uninitialized in this function [-Wuninitialized]
