[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) [From: David Brownell <dbrownell@users.sourceforge.net>] Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
