Crystal Cove and Whiskey Cove are two different PMICs which are
installed on Intel Atom SoC based platforms.

Moreover there are two independent drivers that by some reason were
supposed (*) to get into one kernel module.

Fix the mess by clarifying Kconfig option for Crystal Cove and split
Whiskey Cove out of it.

(*) It looks like the configuration was never tested with
    INTEL_SOC_PMIC=n. The line in Makefile is actually wrong.

<title>mfd: Add support for DA9061</title>

<content type='text'>
MFD support for DA9061 is provided as part of the DA9062 device driver.

The registers header file adds two new chip variant IDs defined in DA9061
and DA9062 hardware. The core header file adds new software enumerations
for listing the valid DA9061 IRQs and a da9062_compatible_types enumeration
for distinguishing between DA9061/62 devices in software.

The core source code adds a new .compatible of_device_id entry. This is
extended from DA9062 to support both "dlg,da9061" and "dlg,da9062". The
.data entry now holds a reference to the enumerated device type.

A new regmap_irq_chip model is added for DA9061 and this supports the new
list of regmap_irq entries. A new mfd_cell da9061_devs[] array lists the
new sub system components for DA9061. Support is added for a new DA9061
regmap_config which lists the correct readable, writable and volatile
ranges for this chip.

The probe function uses the device tree compatible string to switch on the
da9062_compatible_types and configure the correct mfd cells, irq chip and
regmap config.

Kconfig is updated to reflect support for DA9061 and DA9062 PMICs.

These new helpers + macro definitions are meant to replace the old ones
which are unpractical to use.

Note that the macros and function prefixes have been intentionally
changed to ATMEL_[H]SMC_XX and atmel_[h]smc_ to reflect the fact that
this IP is also embedded in avr32 SoCs (and not only in at91 ones).

<content type='text'>
TI LMU (Lighting Management Unit) driver supports lighting devices below.

  LM3532, LM3631, LM3632, LM3633, LM3695 and LM3697.

LMU devices have common features.
  - I2C interface for accessing device registers
  - Hardware enable pin control
  - Backlight brightness control
  - Notifier for hardware fault monitoring
  - Regulators for LCD display bias

It contains fault monitor, backlight, LED and regulator driver.

LMU fault monitor
-----------------
  LM3633 and LM3697 provide hardware monitoring feature.
  It enables open or short circuit detection.
  After monitoring is done, each device should be re-initialized.
  Notifier is used for this case.
  Separate patch for 'ti-lmu-fault-monitor' will be sent later.

Backlight
---------
  It's handled by TI LMU backlight consolidated driver and
  chip dependent data. Separate patchset will be sent later.

LED indicator
-------------
  LM3633 has 6 indicator LEDs. Programmable dimming pattern is also
  supported. Separate patch for 'leds-lm3633' will be sent later.

Regulator
---------
  LM3631 has 5 regulators for the display bias.
  LM3632 supports 3 regulators. One consolidated driver enables it.
  The lm363x regulator driver is already upstreamed.

Many Motorola phones like droid 4 are using a custom PMIC called CPCAP
or 6556002. We can support it's core features quite easily with regmap_spi
and regmap_irq.

The children of cpcap, such as regulators, ADC and USB, can be just regular
device drivers and defined in the dts file. They get probed as we call
of_platform_populate() at the end of our probe, and then the children
can just call dev_get_regmap(dev.parent, NULL) to get the regmap.

This hardware block could at used at same time for PWM generation
and IIO timers.
PWM and IIO timer configuration are mixed in the same registers
so we need a multi fonction driver to be able to share those registers.

version 7:
- rebase on v4.10-rc2

version 6:
- rename files to stm32-timers
- rename functions to stm32_timers_xxx

version 5:
- fix Lee comments about detect function
- add missing dependency on REGMAP_MMIO

version 4:
- add a function to detect Auto Reload Register (ARR) size
- rename the structure shared with other drivers

version 2:
- rename driver "stm32-gptimer" to be align with SoC documentation
- only keep one compatible
- use of_platform_populate() instead of devm_mfd_add_devices()
