+ * Virtual IRQ subsystem after the primary mpc5200 interrupt controller
+ * is initialized.

+ *
+ * This file is a driver for the the General Purpose Timer (gpt) devices
+ * found on the MPC5200 SoC. Each timer has an IO pin which can be used
+ * for GPIO or can be used to raise interrupts. The timer function can
+ * be used independently from the IO pin, or it can be used to control
+ * output signals or measure input signals.
+ *
+ * This driver supports the GPIO and IRQ controller functions of the GPT
+ * device. Timer functions are not yet supported, nor is the watchdog
+ * timer.
+ *
+ * To use the GPIO function, the following two properties must be added
+ * to the device tree node for the gpt device (typically in the .dts file
+ * for the board):
+ * gpio-controller;
+ * #gpio-cells = < 2 >;
+ * This driver will register the GPIO pin if it finds the gpio-controller
+ * property in the device tree.
+ *
+ * To use the IRQ controller function, the following two properties must
+ * be added to the device tree node for the gpt device:
+ * interrupt-controller;
+ * #interrupt-cells = < 1 >;
+ * The IRQ controller binding only uses one cell to specify the interrupt,
+ * and the IRQ flags are encoded in the cell. A cell is not used to encode
+ * the IRQ number because the GPT only has a single IRQ source. For flags,
+ * a value of '1' means rising edge sensitive and '2' means falling edge.
+ *
+ * The GPIO and the IRQ controller functions can be used at the same time,
+ * but in this use case the IO line will only work as an input. Trying to
+ * use it as a GPIO output will not work.
+ *
+ * When using the GPIO line as an output, it can either be driven as normal
+ * IO, or it can be an Open Collector (OC) output. At the moment it is the
+ * responsibility of either the bootloader or the platform setup code to set
+ * the output mode. This driver does not change the output mode setting.
