The main MFD driver for Samsung PMICs (S2MPSXX, S5M876X) used with
Exynos SoCs can be compiled and used as a module. The dependent clock,
regulator and RTC drivers already can be built as a module.
Building entire set of drivers as modules might require using initial
ramdisk and can make booting process longer (due to probe deferrals).
However adding such option is useful for testing and for multi-platform
configurations.
This also add required module authors to sec-irq.c file based on recent

intel_soc_pmic_config_cht_crc based on this.

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.

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

This patch adds the DMI system ID of the Kontron COMe-bBD#, COMe-bKL6,
COMe-cKL6, COMe-bSL6 and COMe-cAL6 boards to the Kontron PLD driver. The
list of supported products in the module description is also updated.

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.

MFD_SUN4I_GPADC and TOUCHSCREEN_SUN4I are incompatible (both are drivers
for Allwinner SoCs' ADC). This makes sure TOUCHSCREEN_SUN4I isn't
enabled while MFD_SUN4I_GPADC is enabled.

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()

The Ricoh RN5T567 is from the same family as the Ricoh RN5T618 is,
the differences are:
+ DCDC4/DCDC5
+ LDO7-10
+ Slightly different output voltage/currents
+ 32kHz Output
+ RTC
+ USB Charger detection

The new sun4i mfd driver is lacking a dependency, triggering very rarely
int randconfig kernel builds:
drivers/mfd/sun4i-gpadc.o: In function `sun4i_gpadc_probe':
sun4i-gpadc.c:(.text.sun4i_gpadc_probe+0x110): undefined reference to `devm_regmap_add_irq_chip'
This adds a 'select REGMAP_IRQ', as the other drivers with this problem do.
