Subject: [PATCH] dt-bindings: rtc: new binding for Raspberry Pi RTC driver
|
|
|
|
Add binding for the new RTC driver for Raspberry Pi.
|
|
This platform has an RTC managed by firmware, and this RTC
|
|
driver provides the simple mailbox interface to access it.

+* Raspberry Pi RTC
|
|
+
|
|
+This is a Linux interface to an RTC managed by firmware, hence it's
|
|
+virtual from a Linux perspective.
|
|
+
|
|
+The interface uses the firmware mailbox api to access the RTC registers.
|
|
+
|
|
+Required properties:
|
|
+compatible: should be "raspberrypi,rpi-rtc"
|
|
+firmware: Reference to the RPi firmware device node.
|
|
+
|
|
+Example:
|
|
+
|
|
+ rpi_rtc: rpi_rtc {
|
|
+ compatible = "raspberrypi,rpi-rtc";
|
|
+ firmware = <&firmware>;
|
|
+ };
