Subject: [PATCH v2 02/11] pinctrl: equilibrium: Make use of struct pinfunction
Date: Tue, 28 May 2024 22:44:53 +0300	[thread overview]
Message-ID: <20240528194951.1489887-3-andy.shevchenko@gmail.com> (raw)
In-Reply-To: <20240528194951.1489887-1-andy.shevchenko@gmail.com>

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

Since pin control provides a generic data type for the pin function,
use it in the driver.
