Subject: [PATCH 1/6] dt-bindings: ti, sci: Add property for partial-io-wakeup-sources
Date: Thu, 23 May 2024 10:02:20 +0200	[thread overview]
Message-ID: <20240523080225.1288617-2-msp@baylibre.com> (raw)
In-Reply-To: <20240523080225.1288617-1-msp@baylibre.com>

Add a property with an array of phandles to devices that have pins that
are capable to wakeup the SoC from Partial-IO. In Partial-IO everything
is powered off including the DDR. Only pins belonging to a couple of
devices are active and wakeup the system on activity.
