media: imagination: Add E5010 JPEG Encoder driver
This adds support for stateful V4L2 M2M based driver for Imagination E5010
JPEG Encoder [1] which supports baseline encoding with two different
quantization tables and compression ratio as demanded.
Support for both contiguous and non-contiguous YUV420 and YUV422 semiplanar
formats is added along with alignment restrictions as required by the
hardware.
System and runtime PM hooks are added in the driver along with v4l2 crop
and selection API support.
Minimum resolution supported is 64x64 and
Maximum resolution supported is 8192x8192.
All v4l2-compliance tests are passing [2] :
v4l2-compliance -s -f -a -d /dev/video0 -e /dev/video1
Total for e5010 device /dev/video0: 79, Succeeded: 79, Failed: 0,

- Multi-instance JPEG Encoding
- DMABUF import, export support
- NV12, NV21, NV16, NV61 video format support
- Compression quality S_CTRL
- Cropping support using S_SELECTION

Logitech C922 internal SOF does not increases at a stable rate of 1kHz.
This causes that the device_sof and the host_sof run at different rates,

Instead of disabling completely the hardware timestamping for such
hardware we take the assumption that the packet handling jitter is
under 2ms and use the host_sof as dev_sof.
We can think of the UVC hardware clock as a system with a coarse clock
(the SOF) and a fine clock (the PTS). The coarse clock can be replaced
with a clock on the same frequency, if the jitter of such clock is
smaller than its sampling rate. That way we can save some of the
precision of the fine clock.
To probe this point we have run three experiments on the Logitech C922.
On that experiment we run the camera at 33fps and we analyse the
difference in msec between a frame and its predecessor. If we display
the histogram of that value, a thinner histogram will mean a better
meassurement. The results for:

- pure software timestamp: https://ibb.co/QC9MgVK

have had the SCR bit set in the header.
This borderline/buggy interpretation has been implemented in a variety
of devices, from directly SunplusIT and from other OEMs that rebrand

The alternative HID for the OV13B10 and the OV08x40 entries both are for

The downside of adding these HIDs is that this will cause the IPU3 / IPU6
drivers to delay registering there /dev/video# nodes until a sensor driver
has bound, which for the non mainline drivers may never happen. This is
not really an issue because almost all IPU designs only have front (user)

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.

HID: i2c-hid: elan: fix reset suspend current leakage
The Elan eKTH5015M touch controller found on the Lenovo ThinkPad X13s
shares the VCC33 supply with other peripherals that may remain powered
during suspend (e.g. when enabled as wakeup sources).
The reset line is also wired so that it can be left deasserted when the
supply is off.
This is important as it avoids holding the controller in reset for
extended periods of time when it remains powered, which can lead to
increased power consumption, and also avoids leaking current through the
X13s reset circuitry during suspend (and after driver unbind).
Use the new 'no-reset-on-power-off' devicetree property to determine
when reset needs to be asserted on power down.
Notably this also avoids wasting power on machine variants without a
touchscreen for which the driver would otherwise exit probe with reset
asserted.

When the power supply is shared with other peripherals the reset line
can be wired in such a way that it can remain deasserted regardless of
whether the supply is on or not.
This is important as it can be used to avoid holding the controller in
reset for extended periods of time when it remains powered, something
which can lead to increased power consumption. Leaving reset deasserted
also avoids leaking current through the reset circuitry pull-up
resistors.
Add a new 'no-reset-on-power-off' devicetree property which can be used
by the OS to determine when reset needs to be asserted on power down.
Note that this property can also be used when the supply cannot be
turned off by the OS at all.
