The card name for ALSA is generated from the model name string and
is limited to 16 characters. Use a shorter name to prevent cutting the
name.
Since nearly all starter kit mainboards for i.MX based SoM by TQ-Systems
use the same codec with the same routing on board it is a good idea to
use the same model name for the sound card. This allows sharing a default

All Skov i.MX8MP boards share the same baseboard (modulo revisions)
and are booted with the same bootloader image, which samples some
strapping pins at startup and determines which kernel device tree
to use.
For use as bootloader device tree and as fallback, when no matching
device tree has been found, add a basic variant that doesn't configure
any variant-specific peripherals like displays.

To reduce heat generation, the Skov i.MX8MP boards should run in nominal

Since commit ff06ea04e4 ("clk: imx: clk-imx8mp: Allow media_disp pixel

The imx8mp-nominal.dtsi is meant to be included into boards that want to
override the default overdrive clock settings with settings suitable for
running in nominal drive mode at its lower required voltage.
Specifying fsl,operating-mode = "nominal" informs drivers of this fact,
so they can sanity check runtime clock reconfiguration to observe the
limits imposed by nominal mode.

Unlike the i.MX8MM and i.MX8MN SoCs added earlier, the device tree for
the i.MX8MP configures some clocks at frequencies that are only validated
for overdrive mode, i.e. when VDD_SOC is 950 mV.
Boards may want to run their SoC at the lower voltage of 850 mV though
to reduce heat generation and power usage. For this to work, clock rates
need to adhere to the limits of the nominal drive mode.
Add an optional DTSI file which can be included by various boards to run
in this mode.

A lot of other clocks on the i.MX8MP, including the DRAM set up by the
bootloader are already running at overdrive clock rates. While this is a
deviation from the configuration of other i.MX8M* family SoCs, overdrive
is the default for most i.MX8MP boards and only some special purpose
boards will choose to run the SoC at nominal drive rates. Up the GPU and
NPU clock rates to their overdrive level to be consistent with other
clocks set up in the dtsi.

A device tree binding for the Microchip USB5744 hub controller
was added in commit 02be19e914 ("dt-bindings: usb: Add support
for Microchip usb5744 hub controller").
U-Boot will consume this binding in order to perform the
necessary actions to enable the USB hub ports over I2C.
(We previously used our own out-of-tree driver for
this task)
The Ten64 board does not have any switchable supplies
for the voltage rails utilized by the USB5744, so a
pair of dummy supplies have been added to facilitate
operation with U-Boot's hub driver.
