Subject: [PATCH v3 5/5] scsi: ufs: qcom: Enable RPM_AUTOSUSPEND for runtime PM
Date: Wed, 4 May 2022 14:12:12 +0530 [thread overview]
Message-ID: <20220504084212.11605-6-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20220504084212.11605-1-manivannan.sadhasivam@linaro.org>
In order to allow the block devices to enter autosuspend mode during
runtime, thereby allowing the ufshcd host driver to also runtime suspend,
let's make use of the RPM_AUTOSUSPEND flag.
Without this flag, userspace needs to enable the autosuspend feature of
the block devices through sysfs.
