4d3e55bc76 mfd: wm8994: Allow to configure CS/ADDR Pulldown from dts
For designs where CS/ADDR pin is floating, it is useful to
allow dts to define whether to keep internal pull down or not.

80d139b863 mfd: rave-sp: Emulate CMD_GET_STATUS on device that don't support it
CMD_GET_STATUS is not supported by some devices implementing
RDU2-compatible ICD as well as "legacy" devices. To account for that
fact, add code that obtains the same information (app/bootloader FW
version) using several different commands.

Relying on serial port defaults for flow control and parity can result
in complete breakdown of communication with RAVE SP on some platforms

LTP Functional tests have caused a bad paging request when triggering

Unable to handle kernel paging request at virtual address ffff0

Investigations have showed that, when triggered by debugfs read()
handler, the mmio regmap logic was reading a bigger (16k) register area
than the one mapped by devm_ioremap_resource() during hi655x-pmic probe
time (4k).

This commit changes hi655x's max register, according to HW specs, to be
the same as the one declared in the pmic device in hi6220's dts, fixing
the issue.

50d44f82c7 mfd: dln2: Use irqsave() in USB's complete callback
The USB completion callback does not disable interrupts while acquiring
the lock. We want to remove the local_irq_disable() invocation from
__usb_hcd_giveback_urb() and therefore it is required for the callback
handler to disable the interrupts while acquiring the lock.
The callback may be invoked either in IRQ or BH context depending on the
USB host controller.
Use the _irqsave() variant of the locking primitives.

f99fea9497 mfd: arizona: Don't use regmap_read_poll_timeout
Some Arizona CODECs have a small timing window where they will
NAK an I2C transaction if it happens before the boot done bit is
set. This can cause the read of the register containing the boot
done bit to fail until it is set. Since regmap_read_poll_timeout
will abort polling if a read fails it can't be reliably used to
poll the boot done bit over I2C.

Do a partial revert of ef84f885e0 ("mfd: arizona: Refactor
arizona_poll_reg"), removing the regmap_read_poll_timeout but
leaving the refactoring to make the arizona_poll_reg take more
sensible arguments.

cd70de2d35 media: platform: Add ChromeOS EC CEC driver
The ChromeOS Embedded Controller can expose a CEC bus, this patch add the
driver for such feature of the Embedded Controller.

This driver is part of the cros-ec MFD and will be add as a sub-device when
the feature bit is exposed by the EC.

The controller will only handle a single logical address and handles
all the messages retries and will only expose Success or Error.

The controller will be tied to the HDMI CEC notifier by using the platform
DMI Data and the i915 device name and connector name.

af8df94587 mfd: da9063: Replace mfd_add_devices with devm counterpart
Use devm_mfd_add_devices() instead of plain mfd_add_devices(), which

.remove callback in da9063-i2c.c .

platform/chrome: Move cros-ec transport drivers to drivers/platform.
There are some cros-ec transport drivers (I2C, SPI) living in MFD, while
others (LPC) living in drivers/platform. The transport drivers are more
platform specific. So, move the I2C and SPI transport drivers to the
platform/chrome directory. The patch also removes the MFD_ prefix of
their Kconfig symbols.
