Subject: [PATCH V2 1/3] scsi: ufs: export api for use in vendor file
Date: Mon, 22 Mar 2021 03:27:35 +0530	[thread overview]
Message-ID: <1616363857-26760-2-git-send-email-nitirawa@codeaurora.org> (raw)
In-Reply-To: <1616363857-26760-1-git-send-email-nitirawa@codeaurora.org>

Exporting functions ufshcd_set_dev_pwr_mode, ufshcd_disable_vreg
and ufshcd_enable_vreg so that vendor drivers can make use of
them in setting vendor specific regulator setting
in vendor specific file.
