15333539a9 regulator: Updates for v3.14
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.

a7c42b2545 mfd: Always assign of_node in mfd_add_device()
mfd_add_device() assigns .of_node in the device objects it creates only
if the mfd_cell for the device has the .of_compatible field set and the
DT node for the top-level MFD device contains a child whose compatible
property matches the cell's .of_compatible field.

This leaves .of_node unset in many cases. When this happens, entries in
the DT /aliases property which refer to the top-level MFD DT node will
never match the MFD child devices, hence causing the requested alias not
to be honored.

Solve this by setting each MFD child device's .of_node equal to the top-
level MFD device's .of_node field in the cases where it would otherwise
remain unset.

01e73c89cf mfd: cros ec: spi: Add delay for raising CS
The EC has specific timing it requires. Add support for an optional delay
after raising CS to fix timing issues. This is configurable based on
a DT property "google,cros-ec-spi-msg-delay".

If this property isn't set, then no delay will be added. However, if set
it will cause a delay equal to the value passed to it to be inserted at
the end of a transaction.

470eca47bd mfd: Add LP3943 MFD driver
LP3943 has 16 output pins which can be used as GPIO expander and PWM generator.

* Regmap I2C interface for R/W LP3943 registers

* Atomic operations for output pin assignment
  The driver should check whether requested pin is available or not.
  If the pin is already used, pin request returns as a failure.
  A driver data, 'pin_used' is checked when gpio_request() and
  pwm_request() are called. If the pin is available, then pin_used is set.
  And it is cleared when gpio_free() and pwm_free().

* Device tree support
  Compatible strings for GPIO and PWM driver.
  LP3943 platform data is PWM related, so parsing the device tree is
  implemented in the PWM driver.

Since we still need to rely on a mix of device tree initialized
drivers and legacy platform data initialize drivers, let's fix
the passing of platform data to twl4030-gpio.

As the twl4030 GPIO is initialized by twl-core.c, we need to register
the auxdata for twl4030 GPIO in twl-core.c.

f6d6daaf9b mfd: sec: Add PM ops and make it a wake up source
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.
