Subject: [PATCH 5.11 19/36] scsi: ufs: Add a quirk to permit overriding UniPro defaults
Date: Wed, 10 Mar 2021 14:23:32 +0100 [thread overview]
Message-ID: <20210310132321.115078931@linuxfoundation.org> (raw)
In-Reply-To: <20210310132320.510840709@linuxfoundation.org>
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
From: Kiwoong Kim <kwmad.kim@samsung.com>
[ Upstream commit b1d0d2eb89d4e3a25b212a9d836587503537067e ]
The UniPro specification states that attribute IDs of the following
parameters are vendor-specific so some SoCs could have no regions at the
defined addresses:
- DME_LocalFC0ProtectionTimeOutVal
- DME_LocalTC0ReplayTimeOutVal
- DME_LocalAFC0ReqTimeOutVal
In addition, the following parameters should be set considering the
compatibility between host and device.
- PA_PWRMODEUSERDATA0
- PA_PWRMODEUSERDATA1
- PA_PWRMODEUSERDATA2
- PA_PWRMODEUSERDATA3
- PA_PWRMODEUSERDATA4
- PA_PWRMODEUSERDATA5
Introduce a quirk to allow vendor drivers to override the UniPro defaults.
