media: ivsc: csi: don't count privacy on as error

commit a813f168336ec4ef725b836e598cd9dc14f76dd7 upstream.

Prior to the ongoing command privacy is on, it would return -1 to
indicate the current privacy status, and the ongoing command would
be well executed by firmware as well, so this is not error. This
patch changes its behavior to notify privacy on directly by V4L2
privacy control instead of reporting error.

media: ivsc: csi: add separate lock for v4l2 control handler

media: ivsc: csi: add separate lock for v4l2 control handler

commit c6be6471004e0e4d10d0514146d8c41550823d63 upstream.

There're possibilities that privacy status change notification happens
in the middle of the ongoing mei command which already takes the command
lock, but v4l2_ctrl_s_ctrl() would also need the same lock prior to this
patch, so this may results in circular locking problem. This patch adds
one dedicated lock for v4l2 control handler to avoid described issue.

media: ivsc: csi: Swap SINK and SOURCE pads

[ Upstream commit 48f5fd8967f8dd01679fc1618b0cba02095cddc5 ]

This patch swaps SINK and SOURCE pads of the MEI CSI sub-device. While
this does change the UAPI by swapping the pads, the driver has never been
usable in upstream kernel as the Intel IPU6 driver it depends on any
functionality has not yet been merged.

Pull media updates from Mauro Carvalho Chehab:

- new i2c drivers: ds90ub913, ds90ub953, ds90ub960, dw9719, ds90ub913

- new Intel IVSC MEI drivers

- some Mediatek platform drivers were moved to a common location

- Intel atomisp2 driver is now working with the main ov2680 driver. Due
to that, the atomisp2 ov2680 staging one was removed

- the bttv driver was finally converted to videobuf2 framework. This
was the last one upstream using videobuf version 1 core. We'll likely
remove the old videobuf framework on 6.7

- lots of improvements at atomisp driver: it now works with normal I2C
sensors. Several compile-mode dependecies to select between ISP2400
and ISP2401 are now solved in runtime

- a new ipu-bridge logic was added to work with IVSC MEI drivers

- venus driver gained better support for new VPU versions

- the v4l core async framework has gained lots of improvements and
cleanups

- lots of other cleanups, improvements and driver fixes

media: pci: intel: ivsc: Add CSI submodule

CSI is a submodule of IVSC which can route camera sensor data
to the outbound MIPI CSI-2 interface.

The interface communicating with firmware is via MEI. There is
a separate MEI UUID, which this driver uses to enumerate.

To route camera sensor data to host, the information of link
frequency and number of data lanes is sent to firmware by
sending MEI command when starting stream.

CSI also provides a privacy mode. When privacy mode is turned
on, camera sensor can't be used. This means that both IVSC and
host Image Processing Unit(IPU) can't get image data. And when
this mode is turned on, user is notified via v4l2 control
callback.
