Marco Felsch 80a21da360 media: tc358746: add Toshiba TC358746 Parallel to CSI-2 bridge driver
Adding support for the TC358746 parallel <-> MIPI CSI bridge. This chip
supports two operating modes:
  1st) parallel-in -> mipi-csi out
  2nd) mipi-csi in -> parallel out

This patch only adds the support for the 1st mode.

Marco Felsch 22168675ba phy: dphy: add support to calculate the timing based on hs_clk_rate
For MIPI-CSI sender use-case it is common to specify the allowed
link-frequencies which should be used for the MIPI link and is
half the hs-clock rate.

This commit adds a helper to calculate the D-PHY timing based on the
hs-clock rate so we don't need to calculate the timings within the
driver.

Laurent Pinchart 6d7a87f2d3 media: i2c: imx290: Fix max gain value
The gain is expressed in multiple of 0.3dB, as a value between 0.0dB
and 72.0dB. Gains between 0.0dB and 30.0dB (included) apply analog gain
only, higher gains from 30.3dB to 72dB apply additional digital gain.

The maximum gain value is erroneously set to 72. Increase it to 100 to
cover the whole analog gain range. Support for digital gain can be added
separately if needed.

The IMX327 and IMX462 are largely compatible with the IMX290, but have
an analog gain range of 0.0dB to 29.4dB and 42dB of digital gain. When
support for those sensors gets added to the driver, the gain control
should be adjusted accordingly.

Laurent Pinchart e611f3dac5 media: i2c: imx290: Simplify error handling when writing registers
Error handling for register writes requires checking the error status of
every single write. This makes the code complex, or incorrect when the
checks are omitted. Simplify this by passing a pointer to an error code
to the imx290_write_reg() function, which allows writing multiple
registers in a row and only checking for errors at the end.

While at it, rename imx290_write_reg() to imx290_write() as there's
nothing else than registers to write, and rename imx290_read_reg()
accordingly.

Sakari Ailus c2079f3e22 media: v4l: subdev: Document s_power() callback is deprecated
Runtime PM has been around for a decade or more, there's hardly a need to
use the V4L2 specific s_power() callback in drivers anymore. Document this
in s_power() callback documentation as well.

Maximilian Luz dc608edf7d ipu3-imgu: Fix NULL pointer dereference in imgu_subdev_set_selection()
Calling v4l2_subdev_get_try_crop() and v4l2_subdev_get_try_compose()
with a subdev state of NULL leads to a NULL pointer dereference. This
can currently happen in imgu_subdev_set_selection() when the state
passed in is NULL, as this method first gets pointers to both the "try"
and "active" states and only then decides which to use.

The same issue has been addressed for imgu_subdev_get_selection() with
commit 30d03a0de650 ("ipu3-imgu: Fix NULL pointer dereference in active
selection access"). However the issue still persists in
imgu_subdev_set_selection().

Therefore, apply a similar fix as done in the aforementioned commit to
imgu_subdev_set_selection(). To keep things a bit cleaner, introduce
helper functions for "crop" and "compose" access and use them in both
imgu_subdev_set_selection() and imgu_subdev_get_selection().

Jason A. Donenfeld ca4582c286 Revert "mfd: syscon: Remove repetition of the regmap_get_val_endian()"
This reverts commit 72a9585972.

It broke reboots on big-endian MIPS and MIPS64 malta QEMU instances,
which use the syscon driver.  Little-endian is not effected, which means
likely it's important to handle regmap_get_val_endian() in this function
after all.

Linus Torvalds 52826d3b2d kernel/utsname_sysctl.c: Fix hostname polling
Commit bfca3dd3d0 ("kernel/utsname_sysctl.c: print kernel arch") added
a new entry to the uts_kern_table[] array, but didn't update the
UTS_PROC_xyz enumerators of older entries, breaking anything that used
them.

Which is admittedly not many cases: it's really just the two uses of
uts_proc_notify() in kernel/sys.c.  But apparently journald-systemd
actually uses this to detect hostname changes.
