Subject: [PATCH v5 02/15] gpio: regmap: set gpio_chip of_node
Date: Sat, 6 Mar 2021 16:56:59 +0100 [thread overview]
Message-ID: <20210306155712.4298-3-noltari@gmail.com> (raw)
In-Reply-To: <20210306155712.4298-1-noltari@gmail.com>
This is needed for properly registering GPIO regmap as a child of a regmap
pin controller.
Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com>
