* MPC5200 General Purpose Timer device driver

* Copyright (c) 2008 Sascha Hauer <s.hauer@pengutronix.de>, Pengutronix

* option) any later version.
*
* 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
