106include the empty property 'fsl,has-wdt'. 106include the empty property 'fsl,has-wdt'. Note that this does not activate
107the watchdog. The timer will function as a GPT if the timer api is used, and
108it will function as watchdog if the watchdog device is used. The watchdog
109mode has priority over the gpt mode, i.e. if the watchdog is activated, any
110gpt api call to this timer will fail with -EBUSY.
111
112If you add the property
113 fsl,wdt-on-boot = <n>;
114GPT0 will be marked as in-use watchdog, i.e. blocking every gpt access to it.
115If n>0, the watchdog is started with a timeout of n seconds. If n=0, the
116configuration of the watchdog is not touched. This is useful in two cases:
117- just mark GPT0 as watchdog, blocking gpt accesses, and configure it later;
118- do not touch a configuration assigned by the boot loader which supervises
119 the boot process itself.
120
121The watchdog will respect the CONFIG_WATCHDOG_NOWAYOUT option.

198In addition to the required compatible-, reg- and interrupt-properites, you can
199also specify which clock source shall be used for the controller:
200
201- fsl,mscan-clock-source- a string describing the clock source. Valid values
202 are: "ip" for ip bus clock
203 "ref" for reference clock (XTAL)
204 "ref" is default in case this property is not

295 vii) Xilinx USB Host controller
296
297 The Xilinx USB host controller is EHCI compatible but with a different
298 base address for the EHCI registers, and it is always a big-endian
299 USB Host controller. The hardware can be configured as high speed only,
300 or high speed/full speed hybrid.

302 Required properties:
303 - xlnx,support-usb-fs: A value 0 means the core is built as high speed
304 only. A value 1 means the core also supports
