The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache.

The driver will match mostly by DT table (even thought there is regular
ID table) so there is little benefit in of_match_ptr (this also allows
ACPI matching via PRP0001, even though it might not be relevant here).
This also fixes !CONFIG_OF error:
drivers/media/i2c/isl7998x.c:1557:34: error: ‘isl7998x_of_match’ defined but not used [-Werror=unused-const-variable=]

After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
commit 03c835f498 ("i2c: Switch .probe() to not take an id parameter")
convert back to (the new) .probe() to be able to eventually drop
.probe_new() from struct i2c_driver.

Don't populate the read-only array isl7998x_video_in_chan_map on the
stack but instead make it static. Also makes the object code a little
smaller.

Pull missed media updates from Mauro Carvalho Chehab:
"It seems I screwed-up my previous pull request: it ends up that only
half of the media patches that were in linux-next got merged in -rc1.
The script which creates the signed tags silently failed due to
5.19->6.0 so it ended generating a tag with incomplete stuff.
So here are the missing parts:
- a DVB core security fix
- lots of fixes and cleanups for atomisp staging driver
- old drivers that are VB1 are being moved to staging to be
deprecated
- several driver updates - mostly for embedded systems, but there are
also some things addressing issues with some PC webcams, in the UVC
video driver"

This driver is using GPIO descriptors but uses the legacy
include header <linux/gpio.h>. Fix it by including the
intended <linux/gpio/consumer.h>.

Add driver for the Intersil ISL7998x Analog to MIPI CSI-2/BT656 decoder.
This chip supports 1/2/4 analog video inputs and converts them into
1/2/4 VCs in MIPI CSI2 stream.
This driver currently supports ISL79987 and both 720x480 and 720x576
resolutions, however as per specification, all inputs must use the
same resolution and standard. The only supported pixel format is now
YUYV/YUV422. The chip should support RGB565 on the CSI2 as well, but
this is currently unsupported.
