Subject: [PATCH stable 5.4 3/7] pinctrl: bcm2835: Add support for all GPIOs on BCM2711
Date: Tue, 25 Jan 2022 11:42:18 -0800 [thread overview]
Message-ID: <20220125194222.12783-4-f.fainelli@gmail.com> (raw)
In-Reply-To: <20220125194222.12783-1-f.fainelli@gmail.com>
From: Stefan Wahren <stefan.wahren@i2se.com>
commit b1d84a3d0a26c5844a22bc09a42704b9371208bb upstream
The BCM2711 supports 58 GPIOs. So extend pinctrl and GPIOs accordingly.
