Subject: [PATCH v4 09/10] scsi: ufs: Export regulator functions
Date: Wed, 15 Jun 2022 11:51:45 +0800	[thread overview]
Message-ID: <20220615035146.20964-10-stanley.chu@mediatek.com> (raw)
In-Reply-To: <20220615035146.20964-1-stanley.chu@mediatek.com>

Export below regulator functions to allow vendors to
customize regulator configuration in their own platforms.

int ufshcd_populate_vreg(struct device *dev, const char *name,
                         struct ufs_vreg **out_vreg);
int ufshcd_get_vreg(struct device *dev, struct ufs_vreg *vreg);
