Add stubs for extcon_register_notifier_all() function for !CONFIG_EXTCON

EXTCON but do not require it (therefore do not depend on CONFIG_EXTCON).

To increase methods to dump more tm info, adds three debugfs commands
to dump tm info of nodes, priority and qset. And a new tm file of debugfs

It breaks clock reparenting via devfreq on the imx8mq used in the

The Bananapi M3 supports a camera module which includes an OV8865 sensor
connected via the parallel CSI interface and an OV8865 sensor connected
via MIPI CSI-2.
The I2C2 bus is shared by the two sensors as well as the (active-low)
reset signal, but each sensor has it own sh
The OV8865 is a 8 Mpx CMOS image sensor producing 3264x2448 at 30 fps.

It outputs 10-bit bayer CFA data through a MIPI CSI-2 interface with
up to 4 lanes supported.
Some register initialisation sequences are still needed for this dr
Besides giving pointers to the relevant functions for PHY mode and

The Allwinner A31 D-PHY supports both Rx and Tx modes. While the latter
is already supported and used for MIPI DSI this adds support for the
former, to be used with MIPI CSI-2.
This implementation is inspired by Allwinner's V3s Linux SDK
implementation, which was used as a documentation base.

In prevision of adding support for this case, set these bits

As some D-PHY controllers support both Rx and Tx mode, we need a way for
