Subject: [PATCH] MLK-20684 PCI: Disable MSI on CYW4356 and CYW4359 chips
|
|
|
|
MSI is broken on CYW4356/4359 chips. This causes CYW4356 1CX not
|
|
work on i.MX8x platforms with bandwidth test. It is known issue
|
|
that i.MX8x PCIe host driver MSI interrupt lost.
|
|
|
|
Disable MSI completely for this chipset to let wifi can stable work
|
|
until PCIe RC driver fix the issue.
