Subject: [PATCH 4/4] ARM: dts: axp22x/axp809: Add GPIO controller nodes
Date: Thu, 16 Jun 2022 01:09:15 -0500	[thread overview]
Message-ID: <20220616060915.48325-5-samuel@sholland.org> (raw)
In-Reply-To: <20220616060915.48325-1-samuel@sholland.org>

These PMICs all contain a GPIO controller. Now that the binding is
documented, wire up the controller in the device tree.
