extcon: max77843: Avoid forcing UART path on drive probe
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.

drm/bridge/sii8620: fix HDMI cable connection to dongle
MHL bridge is usually connected to TV via MHL dongle. Currently plugging
HDMI cable to dongle is handled improperly.
Fix it by splitting connecting of a dongle and a HDMI cable. The driver
should now handle unplugging a sink from a dongle and plugging a
different sink with new edid.
Tested on MHL1, MHL2 and MHL3 using various vendors' dongles both in
DVI and HDMI mode.

The vendor code waits for infoframe to detect video mode set by source.
We do not need to follow this pattern, because video mode information is
