Pull regulator updates from Mark Brown:
 "A respin of the merges in the previous pull request with one extra
  fix.

  A quiet release for the regulator API, quite a large number of small
  improvements all over but other than the addition of new drivers for
  the AS3722 and MAX14577 there is nothing of substantial non-local
  impact"

mfd: sec: Add PM ops and make it a wake up source

2014-01-21T08:13:35+00:00

Add PM suspend/resume ops to the sec MFD core driver and make it a wake
up source. This allows proper waking from suspend to RAM and also fixes
broken interrupts after resuming:
[   42.705703] sec_pmic 7-0066: Failed to read IRQ status: -5

Interrupts stop working after first resume initiated by them (e.g. by
RTC Alarm interrupt) because interrupt registers were not cleared properly.

When device is woken up from suspend by RTC Alarm, an interrupt occurs
before resuming I2C bus controller. The interrupt is handled by
regmap_irq_thread which tries to read RTC registers. This read fails
(I2C is still suspended) and RTC Alarm interrupt is disabled.

Disable the S5M8767 interrupts during suspend (disable_irq()) and enable
them during resume so the device will be still woken up but the interrupt
won't happen before resuming I2C bus.

mfd: Constify struct mfd_cell where possible

2014-01-06T09:13:29+00:00

As of commit 03e361b25ee8dfb1fd9b890072c23c4aae01c6c7 ("mfd: Stop setting
refcounting pointers in original mfd_cell arrays"), the "cell" parameter of
mfd_add_devices() is "const" again. Hence make all cell data passed to
mfd_add_devices() const where possible.

mfd: sec: Remove sec_reg* regmap helpers

2013-12-18T17:25:26+00:00

Remove sec_reg* helpers as they are not used anymore. These helpers were
error-prone as they mixed u8 with unsigned int and they changed order of
some of parameters (val and mask in sec_reg_update()).

Also the helpers didn't give any way of useful abstraction as they just
called corresponding regmap function.

mfd/rtc: s5m: fix register updating by adding regmap for RTC

2013-12-13T02:19:26+00:00

Rename old regmap field of "struct sec_pmic_dev" to "regmap_pmic" and
add new regmap for RTC.

On S5M8767A registers were not properly updated and read due to usage of
the same regmap as the PMIC.  This could be observed in various hangs,
e.g.  in infinite loop during waiting for UDR field change.

On this chip family the RTC has different I2C address than PMIC so
additional regmap is needed.
