Subject: [PATCH v2 1/2] pinctrl: baytrail: drop runtime PM support
Date:   Tue,  3 Oct 2023 17:10:35 +0530
Message-Id: <20231003114036.27674-2-raag.jadav@intel.com>
In-Reply-To: <20231003114036.27674-1-raag.jadav@intel.com>
References: <20231003114036.27674-1-raag.jadav@intel.com>
Precedence: bulk

Since Baytrail pinctrl device is not attached to acpi_lpss_pm_domain,
runtime PM serves no purpose here. Drop it and switch to pm_sleep_ptr()
as now we only have suspend and resume handles in place.
