Icenowy Zheng 1578353e05 mfd: axp20x: Support AXP803 variant
AXP803 is a new PMIC chip produced by X-Powers, usually paired with A64
via RSB bus. The PMIC itself is like AXP288, but with RSB support and
dedicated VBUS and ACIN.

Add support for it in the axp20x mfd driver.

Currently only power key function is supported.

unction devm_regmap_init_i2c() returns an ERR_PTR on errors, and its
return value should be checked before it is dereferenced. However, in
function intel_soc_pmic_i2c_probe(), the return value of function

Tony Lindgren 8b8a84c54a mfd: omap-usb-tll: Fix inverted bit use for USB TLL mode
Commit 16fa3dc75c ("mfd: omap-usb-tll: HOST TLL platform driver")
added support for USB TLL, but uses OMAP_TLL_CHANNEL_CONF_ULPINOBITSTUFF
bit the wrong way. The comments in the code are correct, but the inverted
use of OMAP_TLL_CHANNEL_CONF_ULPINOBITSTUFF causes the register to be
enabled instead of disabled unlike what the comments say.

Without this change the Wrigley 3G LTE modem on droid 4 EHCI bus can
be only pinged few times before it stops responding.

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

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.

Exynos LPASS requires some clocks to be enabled to make any access to its
registers. This patch adds code for handling such clocks. For current set
of registers it is enough to keep sfr0_ctrl clock enabled. Till now it
worked only because those clocks were enabled by bootloader and driver
probe() happened before they were disabled by clock core because of lack
of users. Handling those clocks is also needed to make it possible to

Tony Lindgren ac89473213 mfd: cpcap: Fix interrupt to use level interrupt
I made a mistake assuming the device tree configuration for interrupt
triggering was somehow passed to the SPI device but it's not.

In the Motorola Linux kernel tree CPCAP PMIC is configured as a rising
edge triggered interrupt, but then then it's interrupt handler keeps
looping until the GPIO line goes down. So the CPCAP interrupt is clearly
a level interrupt and not an edge interrupt.

Earlier when I tried to configure it as level interrupt using the
device tree, I did not account that the triggering only gets passed
to the SPI core and it also needs to be specified in the CPCAP driver
when we do devm_regmap_add_irq_chip().

Steve Twiss 656211b1df mfd: Add support for DA9061
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.

Keerthy 85fdaf8eb9 mfd: palmas: Reset the POWERHOLD mux during power off
POWERHOLD signal has higher priority  over the DEV_ON bit.
So power off will not happen if the POWERHOLD is held high.
Hence reset the MUX to GPIO_7 mode to release the POWERHOLD
and the DEV_ON bit to take effect to power off the PMIC.

PMIC Power off happens in dire situations like thermal shutdown
so irrespective of the POWERHOLD setting go ahead and turn off
the powerhold.  Currently poweroff is broken on boards that have
powerhold enabled. This fixes poweroff on those boards.

Charles Keepax ef84f885e0 mfd: arizona: Refactor arizona_poll_reg
Currently, we specify the timeout in terms of the number of polls but it
is more clear from a user of the functions perspective to specify the
timeout directly in milliseconds, as such update the function to these new
semantics.

Additionally, arizona_poll_reg essentially hard-codes
regmap_read_poll_timeout, update the implementation to use
regmap_read_poll_timeout. We still keep arizona_poll_reg around as
regmap_read_poll_timeout is a macro so rather than expand this for each
caller keep it wrapped in arizona_poll_reg.

Whilst we are doing this make the timeouts a little more generous as
the previous system had a bit more slack as it was done as a delay per
iteration of the loop whereas regmap_read_poll_timeout compares ktime's.

Doug Anderson ca691f7118 mfd: cros ec: spi: Increase wait time to 200ms
This is a sucky change to bump up the time we'll wait for the EC.  Why
is it sucky?  If 200ms for a transfer is a common thing it will have a
massively bad impact on keyboard responsiveness.

It still seems like a good idea to do this, though, because we have a
gas gauge that claims that in an extreme case it could stretch the i2c
clock for 144ms.  It's not a common case so it shouldn't affect
responsiveness, but it can happen.  It's much better to have a single
slow keyboard response than to start returning errors when we don't
have to.

In newer EC designs we should probably implement a virtual battery to
respond to the kernel to insulate the kernel from these types of
issues.

Milo Kim d5aa11bfe9 mfd: Add TI LMU driver
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.

Rask Ingemann Lambertsen c0369698e6 mfd: axp20x: Add support for dts property "xpowers,master-mode"
commit b101829a029a ("mfd: axp20x: Fix AXP806 access errors on cold boot")
was intended to fix the case where a board uses an AXP806 in slave mode,
but the boot loader leaves it in master mode for lack of AXP806 support.
But now the driver breaks on boards where the PMIC is operating in master
mode. This patch lets the driver use the new device tree property
"xpowers,master-mode" to set the correct operating mode for the board.

Andy Shevchenko 159ee7578a mfd: intel_soc_pmic_core: Remove unnecessary function
Since commit 845c877009 ("i2c / ACPI: Assign IRQ for devices that have
GpioInt automatically") I2C core assigns interrupt line to I2C slave
devices with regarding to GpioInt() resources.

There is no need to repeat this in the driver.

fail to reboot if the "ti,twl4030-power-idle-osc-off" or
"ti,twl4030-power-idle" compatible flags are set.  This patch will
keep the vmmc1 powered up during reboot allowing the bootloader
