Pull char/misc driver updates from Greg KH:
 "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"

extcon: axp288: Add wakeup support

2020-03-24T23:16:14+00:00

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.

extcon: axp288: Set USB role where necessary

2018-03-22T12:49:28+00:00

The AXP288 BC1.2 charger detection / extcon code may seem like a strange
place to add code to control the USB role-switch on devices with an AXP288,
but there are 2 reasons to do this inside the axp288 extcon code:

1) On many devices the USB role is controlled by ACPI AML code, but the AML
   code only switches between the host and none roles, because of Windows
   not really using device mode. To make device mode work we need to toggle
   between the none/device roles based on Vbus presence, and the axp288
   extcon gets interrupts on Vbus insertion / removal.

2) In order for our BC1.2 charger detection to work properly the role
   mux must be properly set to device mode before we do the detection.

Also note the Kconfig help-text / obsolete depends on USB_PHY which are
remnants from older never upstreamed code also controlling the mux from
the axp288 extcon code.

This commit also adds code to get notifications from the INT3496 extcon
device, which is used on some devices to notify the kernel about id-pin
changes instead of them being handled through AML code.

This fixes:
-Device mode not working on most CHT devices with an AXP288
-Host mode not working on devices with an INT3496 ACPI device
-Charger-type misdetection (always SDP) on devices with an INT3496 when the
 USB role (always) gets initialized as host
