efddff27c8 mfd: max8997: Enale irq-wakeup unconditionally
IRQ wake up support for MAX8997 driver was initially configured by
respective property in pdata. However, after the driver conversion to
device-tree, setting it was left as 'todo'. Nowadays most of other PMIC MFD
drivers initialized from device-tree assume that they can be an irq wakeup
source, so enable it also for MAX8997. This fixes support for wakeup from
MAX8997 RTC alarm.

9f8ddee1da mfd: intel_soc_pmic_bxtwc: Chain power button IRQs as well
Power button IRQ actually has a second level of interrupts to
distinguish between UI and POWER buttons. Moreover, current
implementation looks awkward in approach to handle second level IRQs by
first level related IRQ chip.

To address above issues, split power button IRQ to be chained as well.

55143439b7 mfd: mc13xxx-core: Fix PMIC shutdown when reading ADC values
When trying to read any MC13892 ADC channel on a imx51-babbage board:

The MC13892 PMIC shutdowns completely.

After debugging this issue and comparing the MC13892 and MC13783
initializations done in the vendor kernel, it was noticed that the
CHRGRAWDIV bit of the ADC0 register was not being set.

This bit is set by default after power on, but the driver was
clearing it.

After setting this bit it is possible to read the ADC values correctly.

722fb61e2e mmc: tmio: remove TMIO_MMC_HAVE_HIGH_REG flag
TMIO_MMC_HAVE_HIGH_REG is confusing due to its counter-intuitive name.

All the TMIO MMC variants (TMIO MMC, Renesas SDHI, UniPhier SD) actually
have high registers. It is just that each of them implements its own
registers there. The original IP from Panasonic only defines registers
0x00-0xff in the bus_shift=1 review. The register area above them is
platform-dependent.

In fact, TMIO_MMC_HAVE_HIGH_REG is set only by tmio-mmc.c and used to
test the accessibility of CTL_SDIO_REGS. Because it is specific to
the TMIO MFD variant, the right thing to do is to move such registers
to tmio_mmc.c and delete the TMIO_MMC_HAVE_HIGH_REG flag.

regulator: bd718XX use pickable ranges
Few regulators in BD71837 and BD71847 can output voltages from
different voltage ranges. Register interface is arranged so that
used range is selected by toggling bits which are not next to actual
voltage selection bits. Then the voltage inside selected range is
determined by voltage selection bits (as usual). Support BD71837
and BD71847 selectible range voltages using new pickable ranges

a trivial private structure to store only this pointer. As
the irqchip child driver already has a pointer to the parent
struct madera it can use that to store the pointer. This also
means that the irqchip driver does not need a double-indirection
from its local struct to get at the parent struct madera.

regulator: da9063: fix DT probing with constraints
Commit 1c892e38ce ("regulator: da9063: Handle less LDOs on DA9063L")
reordered the da9063_regulator_info[] array, but not the DA9063_ID_*
regulator ids and not the da9063_matches[] array, because ids are used
as indices in the array initializer. This mismatch between regulator id
and da9063_regulator_info[] array index causes the driver probe to fail
because constraints from DT are not applied to the correct regulator:

  da9063 0-0058: Device detected (chip-ID: 0x61, var-ID: 0x50)
  DA9063_BMEM: Bringing 900000uV into 3300000-3300000uV
  DA9063_LDO9: Bringing 3300000uV into 2500000-2500000uV
  DA9063_LDO1: Bringing 900000uV into 3300000-3300000uV
  DA9063_LDO1: failed to apply 3300000-3300000uV constraint(-22)

This patch reorders the DA9063_ID_* as apparently intended, and with
them the entries in the da90630_matches[] array.

regulator: bd71837: Disable voltage monitoring for LDO3/4
There is a HW quirk in BD71837. The shutdown sequence timings for
bucks/LDOs which are enabled via register interface are changed.
At PMIC poweroff the voltage for BUCK6/7 is cut immediately at the
beginning of shut-down sequence. This causes LDO5/6 voltage
monitoring to detect under voltage and force PMIC to emergency
state instead of poweroff. Disable voltage monitoring for LDO5 and
LDO6 at probe to avoid this.

Immutable branch (mfd, chrome) due for the v4.19 window

Immutable Branch which moves the cros_ec_i2c and cros_ec_spi
transport drivers from mfd to platform/chrome. Changes in arm are a simple
rename in defconfigs. Change in input is a rename in help text.

492510dd7d mfd: da9063: Replace model with type
The model number stored in the struct da9063 is the same for all
variants of the da9063 since it is the chip ID, which is always
the same. Replace that with a separate identifier instead, which
allows us to discern the DA9063 variants by setting the type
based on either DT match or otherwise.

df7878f9dc mfd: da9063: Rename PMIC_DA9063 to PMIC_CHIP_ID_DA9063
The PMIC_DA9063 is a complete misnomer, it denotes the value of the
DA9063 chip ID register, so rename it as such. It is also the value
of chip ID register of DA9063L though, so drop the enum as all the
DA9063 "models" share the same chip ID and thus the distinction will
have to be made using DT or otherwise.

d5318d302e backlight: as3711_bl: Fix Device Tree node leaks
Two framebuffer device-node names were looked up during probe, but were
only used as flags to indicate the presence of two framebuffer device.

Drop the unused framebuffer name along with a likewise unused device
pointer from the driver data, and update the platform data to pass in
booleans instead of the framebuffer strings. This allows us do drop the
node references acquired during probe, which would otherwise leak.

Note that there are no other in-kernel users of the modified
platform-data fields.
