Bug description:
[SRU Justification]
[Impact]
Mediatek FM350-GL wwan module failed to init: Invalid device status
0x1:
[ 1.623253] mtk_t7xx 0000:71:00.0: enabling device (0000 -> 0002)
[ 3.632963] mtk_t7xx 0000:71:00.0: Invalid device status 0x1
[Fix]
The t7xx driver once received following fixes to complete its functions in
v6.1-rc1:
d20ef656f994 net: wwan: t7xx: Add AP CLDMA
007f26f0d68e net: wwan: t7xx: Infrastructure for early port configuration
140424d90165 net: wwan: t7xx: PCIe reset rescan
87dae9e70bf7 net: wwan: t7xx: Enable devlink based fw flashing and coredump
collection
b0bc1709b768 net: wwan: t7xx: Devlink documentation
However it was soon reverted for a second revision. Before that, in bug
1990700
we need the first (reverted) patch "net: wwan: t7xx: Add AP CLDMA" to fix
device
suspend in a minimum level for development. Then, in this bug 2002089, a fully
revised resubmission is now available.
An additional patch from v6.1, commit bb67012331f7 ("net: devlink:
extend info_get() version put to indicate a flash component"), is
necessary for oem-6.0 backport.
[Test Case]
Modprobe on new platforms that suffers this invalid device status issue,
and run suspend/resume tests to ensure bug 1990700 is still in a good
state.
[Where problems could occur]
This re-introduce the device firmware update support via devlink, so far
it has been tested many times from 3rd party/vendor, but might still
bump into platform compatibility issue as we have here.
[Other Info]
While this is only planned for oem-6.0/oem-6.1 and on, only U/L/OEM-6.x
are nominated for fix.
