Subject: [PATCH] pinctrl: meson: amlogic-a4: mark the GPIO controller as sleeping
Date: Tue, 6 Jan 2026 09:52:53 +0100 [thread overview]
Message-ID: <20260106085253.20858-1-bartosz.golaszewski@oss.qualcomm.com> (raw)
The GPIO controller is configured as non-sleeping but it uses generic
pinctrl helpers which use a mutex for synchronization. This will cause
lockdep splats when used together with shared GPIOs going through the
GPIO shared proxy driver.
Fixes: 6e9be3abb78c ("pinctrl: Add driver support for Amlogic SoCs")
Cc: stable@vger.kernel.org
Reported-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com>
Closes: https://lore.kernel.org/all/CAFBinCAc7CO8gfNQakCu3LfkYXuyTd2iRpMRm8EKXSL0mwOnJw@mail.gmail.com/
