What works:
* fngsystem (kirkstone) ramfs boot via uuu
* for UART2 an alias to serial0 is set
* ethernet, at the moment no phy-reg is set explictily
* RTC, we need to check if specific backup source settings are required:
root@FLASH-N-GO:~# dmesg | grep rtc
[    1.519835] snvs_rtc 30370000.snvs:snvs-rtc-lp: registered as rtc1

The Trizeps 8 Plus v1r3 revision has a new audio codec that is not
yet supported. Disable the old codec anyways to prevent from
unexpected behaviour.

A duplicate of the seco logo was present in the logos dir.

The image file for the fngsystem boot logo was missing.
Re-added the file to fix the kernel build.

Both logos need to be enabled by default. The logo that is added to the
kernel is picked through the defconfig and the override in the kernel
include file.

Measured the pixelclock on the lvds interface the frequencies generated
by media_dips2_pix clock do not match the calculated values by the
driver. The driver selects a devider between 1 and 64 ( according to the
    ref manual) but the measured frequencies only end up with
frequencies matching a devider from 1,7,14,21,35.
This patch changes the selected of deviders to that list, so the
frequency is rounded to a actually working frequency.

The imx8mp ldb driver had an hardcoded overwrite for the pixelclock as
the video_pll is not able to generate all needed frequencies.
But the hardcoded value only fits to one mode, probably used on the
EVK.
Removing this override leads to a pixelclock that may be generated with
a devider from the PLL, which ends up with a frquency much closer to what
is expected.

Also it is not the ldb clock but the lcdif clock used for this, so this
seems to be the wrong place for modifying the clock anyway.

For some reason, without the hdmiphy the device stalls during the boot
process. Further investigation into why this happens is required.

The ethernet phy and audio codec have changed in the new revision of the
Trizeps 8 Plus. Removed the unwanted properties from the ethphy0 node
and set the address to 0.
The audio codec hasn't been added yet.

Changed the driver to probe without interrupt gpio, as the irq is not
routed on the trizeps8plus board. It seems to be used for debug output
on pmic errors only, so it should work without.

(cherry picked from commit 3ec08c4d)

The first approach of selecting a RTC didn't work as expected.
The active RTC must reside on the rtc0 alias because otherwise
the hwclock utilities can't access the RTC.
For this to work, we now have a placeholder in the main device tree
that is filled with the actual values in one of the two overlays.
This breaks with the naming conventions for I2C bus devices, but
right now, we don't have a better solution.

The TANARO will be produced with one of two RTC variants.

Replaced imx8mp-pinfunc.h and imx8mp.dtsi with the files provided
with the 5.15 kernel.

Our devicetrees reside in the seconorth sub-directory.

Added missing devicetree include and added the new devicetrees
to the Makefile.

The devicetrees and includes have been copied from the
linux-5.10.9-guf branch.

The enable gpio was used as enable pin and additionally configured as
enable for a regulator. The duplicated usage was not allowed and made
the driver probe fail. For now the tas2552 driver controlls the enable
gpio, which is also only half correct, as the MIC supply is also
controlled with this pin.

Updated the seco logo from the marketing's eps file.

When the probe function returned -EPROBE_DEFER the second call to the probe
failed because the resets couldn't be acquired a second time.
This releases the resets in case of error, so the second call to probe
is able to get the resets.

Copy the files from the 5.10 kernel, except
for imx8mm.dtsi and imx8mm-pinfunc.h which come
from the freescale devicetree directory in the 5.15 kernel.

It seems that there are circumstances when access to QBMAN through the
software portals will be delayed. Accessing some lower speeds interfaces
while also QBMAN commands are issued from the kernel will lead to
software timeouts happening in the dpaa2-eth driver.

What we have observed is that management commands like re-arming the
interrupts on a specific channel, waiting for a dequeue response to be
available etc, will take a longer time to complete.
All these commands have to wait for a valid bit to be set for the
command to be interpreted as successfully completed.

Increase the maximum number of times the Linux kernel drivers will busy
poll for a successful result of one of these commands.

There is a downstream patch which adds a new interface type -
PHY_INTERFACE_MODE_2500SGMII (which is really the same one as
PHY_INTERFACE_MODE_2500BASEX).

We backported from upstream the following phylink patch which, of
course, does not treat the PHY_INTERFACE_MODE_2500SGMII interface mode
in a switch case statement.
	34ae2c09 ("net: phylink: add generic validate implementation")

Because of this, we get the following build warning.

drivers/net/phy/phylink.c: In function ‘phylink_get_linkmodes’:
drivers/net/phy/phylink.c:322:2: warning: enumeration value ‘PHY_INTERFACE_MODE_2500SGMII’ not handled in switch [-Wswitch]
  322 |  switch (interface) {
      |  ^~~~~~

Fix it by treating the new interface mode in the switch-case statement.
