Subject: [PATCH RFC v2 05/14] of: irq: document properties for wakeup interrupt parent
Date: Fri, 13 Sep 2019 15:59:13 -0600 [thread overview]
Message-ID: <1568411962-1022-6-git-send-email-ilina@codeaurora.org> (raw)
In-Reply-To: <1568411962-1022-1-git-send-email-ilina@codeaurora.org>
Some interrupt controllers in a SoC, are always powered on and have a
select interrupts routed to them, so that they can wakeup the SoC from
suspend. Add wakeup-parent DT property to refer to these interrupt
controllers.

+3) Interrupt wakeup parent
+--------------------------
+
+Some interrupt controllers in a SoC, are always powered on and have a select
+interrupts routed to them, so that they can wakeup the SoC from suspend. These
+interrupt controllers do not fall into the category of a parent interrupt
+controller and can be specified by the "wakeup-parent" property and contain a
+single phandle referring to the wakeup capable interrupt controller.
+
+ Example:
+ wakeup-parent = <&pdc_intc>;
