Subject: [PATCH v1] scsi: ufs: modify Tactive time setting conditions
Date: Fri, 7 Jan 2022 04:48:04 +0900 [thread overview]
Message-ID: <20220106194804.23892-1-hy50.seo@samsung.com> (raw)
In-Reply-To: <CGME20220107080332epcas2p216d8123df110623b4287ebf6879f745f@epcas2p2.samsung.com>
The Tactive time determine the waiting time before burst
at hibern8 exit and is determined by H/W at linkup state
However, in the case of samsung devices, guided host's Tactive time +100us
for stability.
If the HCI's Tactive time is equal or greater than the device, +100us should be set.
