Subject: [PATCH v1 2/4] scsi: ufs: Allow WriteBooster on UFS 2.2 devices
Date: Tue, 12 May 2020 18:47:48 +0800	[thread overview]
Message-ID: <20200512104750.8711-3-stanley.chu@mediatek.com> (raw)
In-Reply-To: <20200512104750.8711-1-stanley.chu@mediatek.com>

According to the UFS specification, WriteBooster is officially
supported by UFS 2.2.

Since UFS 2.2 specification has been finalized in JEDEC and
such devices have also showed up in the market, modify the
checking rule for ufshcd_wb_probe() to allow these devices to enable
WriteBooster.
