Subject: [PATCH v1 1/4] pinctrl: intel: export common pinctrl functions
Date:   Mon, 14 Aug 2023 11:33:08 +0530
Message-Id: <20230814060311.15945-2-raag.jadav@intel.com>
In-Reply-To: <20230814060311.15945-1-raag.jadav@intel.com>
References: <20230814060311.15945-1-raag.jadav@intel.com>
Precedence: bulk

Export common pinctrl functions that are used across Intel specific
platform drivers, so that they can be reused.
