Pull char/misc update part 2 from Greg KH:
"Here is the "real" big set of char/misc driver patches for 5.2-rc1
Loads of different driver subsystem stuff in here, all over the places:
- 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"

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.

As Hans de Goede pointed, using this driver without ACPI

The PTN5150 dependencies look like they were meant to do the
right thing, but they actually should not allow building without
I2C for compile testing, as that results in a Kconfig warning

MAX8997 driver disables automatic path selection from MicroUSB connector
and manually sets path to either UART or USB lines. However the code for
setting USB path worked only for USB host mode (when ID pin is set
to ground). When standard USB cable (USB device mode) is connected, path
registers are not touched. This means that once the non-USB accessory is
connected to MAX8997-operated micro USB port, the path is no longer set
to USB and USB device mode doesn't work. This patch fixes it by setting
USB path both for USB and USB host modes.

Driver unconditionally forces UART path during probe, probably to ensure
that one can get kernel serial log as soon as possible.
This approach causes some issues, especially when board is booted with
non-UART cable connected to micro-USB port. For example, when USB cable is
connected, UART TX/RX lines are unconditionally short-circuited to USB
D+/D- lines. This is in turn recognized by a series of serial BREAK
signals and some random characters when USB host tries to perform
enumeration procedure.
To solve the above issue and keep UART console operational as early as
possible, set UART path only when USB ID reports UART capable cable.
