title: PowerQUICC CPM Time-slot assigner (TSA) controller

maintainers:
  - Herve Codina <herve.codina@bootlin.com>

description:
  The TSA is the time-slot assigner that can be found on some PowerQUICC SoC.
  Its purpose is to route some TDM time-slots to other internal serial
  controllers.

        description:
          The hardware can use four dedicated pins for Tx clock, Tx sync, Rx
          clock and Rx sync or use only two pins, Tx/Rx clock and Tx/Rx sync.
          Without the 'fsl,common-rxtx-pins' property, the four pins are used.
          With the 'fsl,common-rxtx-pins' property, two pins are used.
