Subject: [PATCH] rtc: rtc-at91sam9.c add DT support
Date: Wed, 03 Apr 2013 23:54:45 -0400 [thread overview]
Message-ID: <515CF985.6050009@interlog.com> (raw)
Some members of the at91 SoCs use the Real Time Timer (RTT)
and the General Purpose Backup Registers (GPBR) to implement
a real time clock (RTC). The AT91SAM9G20 is one example.
Attached is a patch to add DT support to rtc-at91sam9.c .
The patch is against lk 3.9.0-rc5 .
Below is a snippet of DT code for the 'G20 that was observed
to work with this patch:
ahb {
apb {
rtc {
compatible = "atmel,at91sam9-rtc";
/* RTTC followed by GPBR (backup registers) */
reg = <0xfffffd20 0x10>, <0xfffffd50 0x10>;
interrupts = <1 4 7>;
status = "okay";
};
}
};
