One question for Benoit, Grant or Rob:
+Required properties:
+- compatible: should be "mrvl,sa1100-rtc"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- interrupts: Should be two. The first interrupt number is the rtc alarm
+ interrupt and the second interrupt number is the rtc hz interrupt.
+- interrupt-names: Assign name of irq resource.
+
+Example:
+ rtc: rtc@d4010000 {
+ compatible = "mrvl,mmp-rtc";
+ reg =<0xd4010000 0x1000>;
+ interrupts =<5>,<6>;
+ interrupt-name = "rtc 1Hz", "rtc alarm";
+ };
When the binding for a device lists the interrupt-names property, should it
also list the specific values for it? This one says that which ones they are,
but I think we should actually mandate the exact string in the binding if
we want to allow drivers to get the resource by its name.
Yes, indeed. The names are not some random strings, the driver will use
get_resource_by_name and expect the name to be aligned with HW
documentation and thus should be well documented in the binding.
Regards,
Benoit
