[PATCH 0/2] Add MSI driver support for the Lightning Mountain SoC

Posted by Florian Eckert 2 weeks, 5 days ago

The Lightning Mountain (LGM) does have an MSI irqchip connected to the
x86 vector domain. This series adds the driver and the devicetree binding
for this MSI IP core.

Maxlinear acquired Intel’s Home Gateway Platform Division (formerly Lantiq)
in 2020. The following SoCs do have this IP core [1].

* URX851
* URX850

The source files were extracted from the Maxlinear open-source kernel,
which is publicly available on GitHub [2].
