Subject: [PATCH AUTOSEL 5.5 11/58] qmi_wwan: re-add DW5821e pre-production variant
Date: Sat, 22 Feb 2020 21:20:32 -0500 [thread overview]
Message-ID: <20200223022119.707-11-sashal@kernel.org> (raw)
In-Reply-To: <20200223022119.707-1-sashal@kernel.org>
From: Bjørn Mork <bjorn@mork.no>
[ Upstream commit 88bf54603f6f2c137dfee1abf6436ceac3528d2d ]
Commit f25e1392fdb5 removed the support for the pre-production variant
of the Dell DW5821e to avoid probing another USB interface unnecessarily.
However, the pre-production samples are found in the wild, and this lack
of support is causing problems for users of such samples. It is therefore
necessary to support both variants.
Matching on both interfaces 0 and 1 is not expected to cause any problem
with either variant, as only the QMI function will be probed successfully
on either. Interface 1 will be rejected based on the HID class for the
production variant:
T: Bus=01 Lev=03 Prnt=04 Port=00 Cnt=01 Dev#= 16 Spd=480 MxCh= 0
D: Ver= 2.10 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs= 2
P: Vendor=413c ProdID=81d7 Rev=03.18
S: Manufacturer=DELL
S: Product=DW5821e Snapdragon X20 LTE
S: SerialNumber=0123456789ABCDEF
C: #Ifs= 6 Cfg#= 1 Atr=a0 MxPwr=500mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=qmi_wwan
I: If#= 1 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=00 Prot=00 Driver=usbhid
I: If#= 2 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=00 Prot=00 Driver=option
I: If#= 3 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=00 Prot=00 Driver=option

I: If#= 5 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
And interface 0 will be rejected based on too few endpoints for the
pre-production variant:
T: Bus=01 Lev=02 Prnt=02 Port=03 Cnt=03 Dev#= 7 Spd=480 MxCh= 0
D: Ver= 2.10 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs= 2
