Subject: [PATCH v2 4/4] ARM: dts: axp22x/axp809: Add GPIO controller nodes
Date: Mon, 20 Jun 2022 22:42:24 -0500 [thread overview]
Message-ID: <20220621034224.38995-5-samuel@sholland.org> (raw)
In-Reply-To: <20220621034224.38995-1-samuel@sholland.org>
These PMICs all contain a GPIO controller. Now that the binding is
documented, wire up the controller in the device tree.
Signed-off-by: Samuel Holland <samuel@sholland.org>
