Subject: [PATCH v2 05/12] of: irq: document properties for wakeup interrupt parent
Date: Fri, 15 Nov 2019 15:11:48 -0700	[thread overview]
Message-ID: <1573855915-9841-6-git-send-email-ilina@codeaurora.org> (raw)
In-Reply-To: <1573855915-9841-1-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>;
