[ARM] 4752/1: [AT91] RTT, RTC and WDT peripherals on SAM9
Add platform_device and initialization for the RTT (Real Time Timer)
and WDT (Watchdog) integrated in the Atmel AT91SAM9 processors.
For SAM9263, register both RTT peripherals.
[From: David Brownell <dbrownell@users.sourceforge.net>]
Provide platform_resources for RTT peripherals
[From: David Brownell <dbrownell@users.sourceforge.net>]
Add support for RTC peripheral on AT91SAM9RL (same RTC peripherals as
AT91RM9200)
