14 * This driver supports the GPIO and IRQ controller functions of the GPT
18 * this prevents the use of any gpt0 gpt function (i.e. they will fail with

107 the watchdog. The timer will function as a GPT if the timer api is used, and
109 mode has priority over the gpt mode, i.e. if the watchdog is activated, any
110 gpt api call to this timer will fail with -EBUSY.
114 GPT0 will be marked as in-use watchdog, i.e. blocking every gpt access to it.
117 - just mark GPT0 as watchdog, blocking gpt accesses, and configure it later;
123 An mpc5200-gpt can be used as a single line GPIO controller. To do so,
124 add the following properties to the gpt node:
