Subject: [PATCH] arm64: dts: rockchip: rk356x: Move PCIe MSI to use GIC
|
|
ITS instead of MBI
|
|
|
|
Rockchip 356x device-tree now supports GIC ITS. Move PCIe controller's
|
|
MSI to use ITS instead of MBI. This removes extra CPU overhead of handling
|
|
PCIe MBIs by letting GIC's ITS to serve the PCIe MSIs.
