+description:
+  The GSBI controller is modeled as a node with zero or more child nodes, each
+  representing a serial sub-node device that is mux'd as part of the GSBI
+  configuration settings.  The mode setting will govern the input/output mode
+  of the 4 GSBI IOs.
+
+  A GSBI controller node can contain 0 or more child nodes representing serial
+  devices.  These serial devices can be a QCOM UART, I2C controller, spi
+  controller, or some combination of aforementioned devices.
