+====================================
+
+TQMa series
+-----------
+
+TQMa is a series of System-on-Modules (SoM) targeting industrial control
+systems due to the long-term availability and extended temperature range.
+They are available with a number of different System-on-Chips (SoC).
+The TQMa7 module can only be mounted with NXP i.MX7 Solo or Dual SoCs.
+Primary compatible strings are of the form "tq,<SoC>-<SoM>".
+
+TQMa7S SoM
+Required root node properties:
+ - compatible = "tq,imx7s-tqma7", "fsl,imx7s";
+
+TQMa7D SoM
+Required root node properties:
+ - compatible = "tq,imx7d-tqma7", "fsl,imx7d";
+
+MBa series
+----------
+
+MBa is a series of Carrier Boards / Single Board Computers (SBC) for
+evaluation of TQMa SoMs.
+The MBa7 carrier board can only interface with TQMa7 modules.
+Primary compatible strings are of the form "tq,<SoC>-<SBC>".
+
+MBa7 with TQMa7S SoM
+Required root node properties:
+ - compatible = "tq,imx7s-mba7", "tq,imx7s-tqma7", "fsl,imx7s";
+
+MBa7 with TQMa7D SoM
+Required root node properties:
+ - compatible = "tq,imx7d-mba7", "tq,imx7d-tqma7", "fsl,imx7d";
