Subject: [PATCH v1 1/1] pinctrl: armada-37xx: Switch to use fwnode instead of of_node
Date: Fri, 25 Mar 2022 22:14:25 +0200	[thread overview]
Message-ID: <20220325201425.54847-1-andriy.shevchenko@linux.intel.com> (raw)

GPIO library now accepts fwnode as a firmware node,
so switch the driver to use it.
