Without the MFD driver, we run into a link error:
drivers/media/platform/cros-ec-cec/cros-ec-cec.o: In function `cros_ec_cec_transmit':
cros-ec-cec.c:(.text+0x474): undefined reference to `cros_ec_cmd_xfer_status'

cros-ec-cec.c:(.text+0x77d): undefined reference to `cros_ec_cmd_xfer_status'
As we can compile-test all the dependency, the extra '| COMPILE_TEST' is
not needed to get the build coverage, and we can simply turn MFD_CROS_EC
into a hard dependency to make it build in all configurations.

In case of Device Tree platforms, even though the Samsung PMIC sec
device is instantiated from DT, the driver is still matched through I2C
module alias. That is because I2C core always reports an I2C module
alias instead of DT one.
This could change in the future so export DT module alias.

The Pine64 H64 board uses an AXP806 PMIC in I2C and self-working mode.
The H64 SoC does not have the usual RSB controller.
This patch adds AXP806 to the list of devices supported in I2C mode.
In theory, all RSB-based PMICs can also be used in I2C mode.

The AXP806 can operate in a standalone "self-working" mode, in which it
is also responsible for power control of the overall system. This mode
is similar to the master mode, but the EN/PWRON pin functions as a power
button, instead of a level-triggered enable switch.
This patch adds code checking for the new "x-powers,self-working-mode"
property, and a separate mfd_cell list that includes the power button
(PEK) sub-device.

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.

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 ef84f885e037 ("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.

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.

In non device-tree world, we can need to get the notifier by the driver
name directly and eventually defer probe if not yet created.
This patch adds a variant of the get function by using the device name
instead and will not create a notifier if not yet created.
But the i915 driver exposes at least 2 HDMI connectors, this patch also
adds the possibility to add a connector name tied to the notifier device
to form a tuple and associate different CEC controllers for each HDMI

Pull block fixes from Jens Axboe:
"Small set of fixes for this series. Mostly just minor fixes, the only
oddball in here is the sg change.
The sg change came out of the stall fix for NVMe, where we added a
mempool and limited us to a single page allocation. CONFIG_SG_DEBUG
sort-of ruins that, since we'd need to account for that. That's
actually a generic problem, since lots of drivers need to allocate SG
lists. So this just removes support for CONFIG_SG_DEBUG, which I added
back in 2007 and to my knowledge it was never useful.
Anyway, outside of that, this pull contains:
- clone of request with special payload fix (Bart)
- drbd discard handling fix (Bart)
- SATA blk-mq stall fix (me)
- chunk size fix (Keith)
- double free nvme rdma fix (Sagi)"
* tag 'for-linus-20180629' of git://git.kernel.dk/linux-block:
sg: remove ->sg_magic member
drbd: Fix drbd_request_prepare() discard handling
blk-mq: don't queue more if we get a busy return
block: Fix cloning of requests with a special payload
nvme-rdma: fix possible double free of controller async event buffer
block: Fix transfer when chunk sectors exceeds max

This was introduced more than a decade ago when sg chaining was
added, but we never really caught anything with it. The scatterlist
entry size can be critical, since drivers allocate it, so remove
the magic member. Recently it's been triggering allocation stalls
and failures in NVMe.
