[PATCH v3 0/7] Support for some TQMa8M* boards

[Alexander Stein]

Thanks for the review on v2!

Changes in v3:
* Rebased to next-20211129
* Adjusted commit subjects (tree -> device tree)
* Use hyphen in node names instead of underscore
* Removed bootargs from DT
* Fixed audio-codec node name and handle name
* Property 'enet-phy-lane-no-swap' was already documented, but got accidently
  removed during YAML conversion. Fix is pending at at [2]
* Use matrix instead of array for 'fsl,pins' as required by pinctrl bindings.
  This reduces the lines in stderr from dtbs_check for these DT files from 475
  down to 191
* Removed TODO regarding unsupported USB over-current polarity

Changes in v2:
* Rebased to next-20211101
* Added Rob's Acked-By on Patch for DT bindings
* for other changes please refer to individual patches

Note on TQMa8Mx:
Due to CPU errata cpuidle is broken and needs to be disabled, see [1] for
pending patch.

This patch set adds support for the following modules:
* TQMa8Mx
* TQMa8MxML
* TQMa8MxNL

Each of the modules is available with different i.MX8M variants, the
bootloader modifies the device tree and disabled paripherals which
are not available on the actual hardware.

All of them can be attached to the same mainboard MBa8Mx, although
TQMa8MxML & TQMa8MxNL need an adapter. For that reason there is a single
mainboard .dtsi file named mba8mx.dtsi.

There is a .dtsi file for each module named imx8m?-tmqa8m*.dts.

Finally there is the final .dts file which includes the mainboard and
the attached module and contains the missing connection, prominently clk
and pinctrl defines.
