This is MFD module providing access to registers and interrupts of DA906x
series PMIC. It is used by other functional modules, registered as MFD cells.
Driver uses regmap with paging to access extended register list. Register map
is divided into two pages, where the second page is used during initialisation.

This module provides support to following functional cells:
 - Regulators
 - RTC
 - HWMON
 - OnKey (power key misc input device)
 - Vibration (force-feedback input device)
 - Watchdog
 - LEDs

ADC is ideally expected to work at a frequency of 3MHz.
The present code had a check, which returned error if the frequency
went below the threshold  value. But since AM335x supports various
working frequencies, this check is not required.
Now the code just uses the internal ADC clock divider to set the ADC
frequency w.r.t the sys clock.

Since enabling VMID takes a runtime PM reference there is no need to
suppress suspend when doing a runtime suspend. Similarly the digital
inputs and outputs are DAPM widgets and therefore the ASoC core will
be holding a reference for them.

This used to be required when integration with system suspend was being
bodged.

The performance of regmap-irq is improved if the interrupt mask registers
can be cached since it does read/modify/update cycles so start using the
register cache infrastructure for those registers. We should use this more

starting point.

This patch clears all the events received while powering up DA9055.

While powering up DA9055, both power sequencer and gpio events are received.
These events remain uncleared after boot up, due to which further event handling
also fails. DA9055 has three event registers. The event register bits are set
to '1' on receiving an event. The events can be cleared on writing a '1' to
the set bit, which would then clear that bit to '0'. After applying this patch
we have a clean state after boot up.

The Patch adds TPS659038 PMIC support in the palmas mfd driver.
The TPS659038 has almost the same registers as of the earlier
supported variants of PALMAS family such as the TWL6035.

The critical differences between TPS659038 and TWL6035 being:

1) TPS659038 has nothing related to battery charging and back up battery stuff.
2) TPS659038 does not have does not have SMPS10(Boost) step up convertor.
3) TPS659038 does not have Battery detection and anything related to battery.
4) SD card detection, Battery presence detection, Vibrator, USB OTG are missing
   when compared to TWL6035.

The genirq IRQ wake method will default to failure if the irq_chip
does not provide a set_wake method.  However, for TWL4030 sub-chip
IRQs, we want the wake enable to succeed even though we don't provide
a set_wake method.  This allows sub-chip IRQs to still be flagged as
wakeup capable, and allow them to wakeup from suspend (or abort
suspend if they fire during suspend.)

To fix, use the IRQCHIP_SKIP_SET_WAKE flag in the irq_chip.
