In the DP-driver there is "qcom,edp-vcc-en-gpio" that a gpio can be
assigned to in the DT and that powers on the display. But this gpio is
switched AFTER the display has been powered on. Thus there is no other
way to turn on a display but using a hog-gpio.

There is no way to assign a backlight-device to (e)DP, not even a PWM,
only a bunch of gpios. So the pwm is configured as gpio, meaning there is
no way to adjust the backlight-brightness but 2 ways to switch the
backlight off, because both gpios must be high.

This is used to enable an eDP with a hog-gpio

This also introduces a more logical naming convention:
seco-<soc>-<som>-<baseboard>-<display>.dts

dtsi-files for baseboards are prefixed with "baseboard-" and those for
displays with "display-".

The QCS5430 is a QCS6490 that is lacking some features, so we use the
QCS6490 dtsi-file for both and disable the non-existing features for
QCS5430. The opposite way would be less ugly but would require modification
of the Qualcomm-provided dtsi-files.

Qualcomm uses off-tree device-tree-overlays for displays. These overlays are
applied to the base device-tree at build time to generate a combined device-
tree.
Because they are maintained in separate repositories they do not necessarily
match the kernel. If so, for the dtc everything seems to be right, because it
has no knowledge about the base device-tree. The errors, like the most common
"unknown label" because of a simple typo, occure later when the overlays are
applied. While the dtc says: this file, this line, this error, the tool that
applies the overlays only says "FDT_ERR_NOTFOUND", hidden somewhere in the
bitbake-logs, and it takes hours and hours of trial-and-error to figure out
what went wrong.
Furthermore, because the overlays are not applied dynamically at runtime but
at build-time, it does not make any sense to use overlays. They cause nothing
but trouble. For this reasons th overlays have been turned to dtsi-files.

Even without development is unconvenient enough

- Fix the main comments to reflect the devicetree files correctly
- Update the copyright

Rename the B79 include file and also add the file -b79 file extension to
the base devicetrees.

Remove reference to qcs6490 as E81 has both qcs6490 and qcs5430

usb_1 is a little bit weird, copied from qcom-device-trees

We have 5 UARTs in E81 design,
accordingly increasing the number of possible uarts.

For three options:
- QCS6490
- QCS5430 FP1
- QCS5430 FP2

TX-coalescing configuration

When changing the interface from CAN-CC to CAN-FD mode the old
coalescing parameters are re-used. This might cause problem, as the
configured parameters are too big for CAN-FD mode.

During testing an invalid TX coalescing configuration has been seen.
The problem should be been fixed in the previous patch, but add a
safeguard here to ensure that the number of TEF coalescing buffers (if
configured) is exactly the half of all TEF buffers.

into mcp251xfd_chip_start/stop()

The mcp251xfd wakes up from Low Power or Sleep Mode when SPI activity
is detected. To avoid this, make sure that the timestamp worker is
stopped before shutting down the chip.

Split the starting of the timestamp worker out of
mcp251xfd_timestamp_init() into the separate function
mcp251xfd_timestamp_start().

Call mcp251xfd_timestamp_init() before mcp251xfd_chip_start(), move
mcp251xfd_timestamp_start() to mcp251xfd_chip_start(). In this way,
mcp251xfd_timestamp_stop() can be called unconditionally by
mcp251xfd_chip_stop().
