[PATCH v3 1/3] dt-bindings: arm: fsl: add TQ-Systems boards based on i.MX6Q/QP/DL

[Matthias Schiffer]

The TQ-Systems MBa6x mainboard can be used with TQMa6 variants with
i.MX6Q/QP/DL SoCs (TQMa6Q/QP/DL). The TQMa6Q and DL exist in two variants:
The newer variants "A" have a hardware workaround for Erratum ERR006687,
while variants "B" are missing such a workaround, so it needs to be
handled in software. The erratum was fixed in i.MX6QP, so no "A" variant
of the TQMa6QP exists.

[PATCH v3 2/3] ARM: dts: imx6qdl-tqma6: add ERR006687 hardware workaround for "a" variant

[Matthias Schiffer]

The TQMa6x "a" has a workaround for ERR006687 implemented in hardware.
Add the required pinmuxing and related setup to make use of this.

As board DTS files based on the TQMa6x SoMs will define their own
pinmuxing for the FEC ethernet controller as well, we can't apply this
pin group unconditionally; instead, it is the responsibility of the
board DTs derived from imx6qdl-tqma6a.dtsi to include this group.

[PATCH v3 3/3] ARM: dts: imx6qdl: add TQ-Systems MBa6x device trees

[Matthias Schiffer]

From: Markus Niebel <Markus.Niebel@ew.tq-group.com>

Add device trees for the MBa6x mainboard with TQMa6Q/QP/DL SoMs.

As discussed, all new files are added with GPL-2.0-only license, as they
are too tightly intertwined with the SoC DTSIs imx6dl.dtsi and imx6q.dtsi,
which are GPL-2.0.

v2: changed SPDX-License-Identifier of new files to GPL-2.0-only as
suggested by Rob Herring.
v3: applied minor fixes suggested by Shawn Guo
