Subject: [PATCH] gpio: pca9570: add pca9571 support
Date: Fri, 10 Jun 2022 18:48:55 +0200 [thread overview]
Message-ID: <20220610164855.242563-1-l.stach@pengutronix.de> (raw)
The PCA9571 very similar to the PCA9570, it only differs in the
number of GPIOs.
Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
