Subject: [PATCH RESEND v3 1/5] scsi: ufs: Remove unused min_uA field in struct ufs_vreg
Date: Wed, 27 Mar 2019 17:58:23 +0800 [thread overview]
Message-ID: <1553680707-28579-2-git-send-email-stanley.chu@mediatek.com> (raw)
In-Reply-To: <1553680707-28579-1-git-send-email-stanley.chu-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>
There are two fields related to regulator current limit in struct
ufs_vreg: "min_uA" and "max_uA".
"max_uA" is probed by "<name>-max-microamp" property from device
tree and used for
- regulator_set_load operations, and
- icc_level configuration in device.
However "min_uA" field is not used anywhere, thus we can remove it.
