Linus Torvalds 0ad5b053d4 Char/Misc driver patches for 5.7-rc1
Here is the big set of char/misc/other driver patches for 5.7-rc1.
 
 Lots of things in here, and it's later than expected due to some reverts
 to resolve some reported issues.  All is now clean with no reported
 problems in linux-next.
 
 Included in here is:
 	- interconnect updates
 	- mei driver updates
 	- uio updates
 	- nvmem driver updates
 	- soundwire updates
 	- binderfs updates
 	- coresight updates
 	- habanalabs updates
 	- mhi new bus type and core
 	- extcon driver updates
 	- some Kconfig cleanups
 	- other small misc driver cleanups and updates
 
 As mentioned, all have been in linux-next for a while, and with the last
 two reverts, all is calm and good.

Hans de Goede 9c94553099 extcon: axp288: Add wakeup support
On devices with an AXP288, we need to wakeup from suspend when a charger
is plugged in, so that we can do charger-type detection and so that the
axp288-charger driver, which listens for our extcon events, can configure
the input-current-limit accordingly.

Stephan Gerhold 6942635032 extcon: sm5502: Reset registers during initialization
On some devices (e.g. Samsung Galaxy A5 (2015)), the bootloader
seems to keep interrupts enabled for SM5502 when booting Linux.
Changing the cable state (i.e. plugging in a cable) - until the driver
is loaded - will therefore produce an interrupt that is never read.

In this situation, the cable state will be stuck forever on the
initial state because SM5502 stops sending interrupts.
This can be avoided by clearing those pending interrupts after
the driver has been loaded.

One way to do this is to reset all registers to default state
by writing to SM5502_REG_RESET. This ensures that we start from
a clean state, with all interrupts disabled.

Enric Balletbo i Serra 840d9f131f mfd / platform: cros_ec: Reorganize platform and mfd includes
There is a bit of mess between cros-ec mfd includes and platform
includes. For example, we have a linux/mfd/cros_ec.h include that
exports the interface implemented in platform/chrome/cros_ec_proto.c. Or
we have a linux/mfd/cros_ec_commands.h file that is non related to the
multifunction device (in the sense that is not exporting any function of
the mfd device). This causes crossed includes between mfd and
platform/chrome subsystems and makes the code difficult to read, apart
from creating 'curious' situations where a platform/chrome driver includes
a linux/mfd/cros_ec.h file just to get the exported functions that are
implemented in another platform/chrome driver.

In order to have a better separation on what the cros-ec multifunction
driver does and what the cros-ec core provides move and rework the
affected includes doing:

 - Move cros_ec_commands.h to include/linux/platform_data/cros_ec_commands.h
 - Get rid of the parts that are implemented in the platform/chrome/cros_ec_proto.c
   driver from include/linux/mfd/cros_ec.h to a new file
   include/linux/platform_data/cros_ec_proto.h
 - Update all the drivers with the new includes, so
   - Drivers that only need to know about the protocol include
     - linux/platform_data/cros_ec_proto.h
     - linux/platform_data/cros_ec_commands.h
   - Drivers that need to know about the cros-ec mfd device also include
     - linux/mfd/cros_ec.h

Linus Walleij 6527c6856f extcon: fsa9480: Support the FSA880 variant
The older compatible variant of this chip is called FSA880
and works the same way, if we need some quirks in the future,
it is good to let it have its own compatible string.

Linus Torvalds f678d6da74 Char/Misc patches for 5.2-rc1 - part 2
Here is the "real" big set of char/misc driver patches for 5.2-rc1

   - thunderbolt driver updates
   - habanalabs driver updates
   - nvmem driver updates
   - extcon driver updates
   - intel_th driver updates
   - mei driver updates
   - coresight driver updates
   - soundwire driver cleanups and updates
   - fastrpc driver updates
   - other minor driver updates
   - chardev minor fixups
 
 Feels like this tree is getting to be a dumping ground of "small driver
 subsystems" these days.  Which is fine with me, if it makes things
 easier for those subsystem maintainers.
 
 All of these have been in linux-next for a while with no reported
 issues.

Charles Keepax 00053de522 extcon: arizona: Disable mic detect if running when driver is removed
Microphone detection provides the button detection features on the
Arizona CODECs as such it will be running if the jack is currently
inserted. If the driver is unbound whilst the jack is still inserted
this will cause warnings from the regulator framework as the MICVDD
regulator is put but was never disabled.

Correct this by disabling microphone detection on driver removal and if
the microphone detection was running disable the regulator and put the
runtime reference that was currently held.
