Subject: [PATCH 4/6] net: airoha: npu: Read NPU wlan interrupt lines from the
|
|
DTS
|
|
|
|
Read all NPU wlan IRQ lines from the NPU device-tree node.
|
|
NPU module fires wlan irq lines when the traffic to/from the WiFi NIC is
|
|
not hw accelerated (these interrupts will be consumed by the MT76 driver
|
|
in subsequent patches).
|
|
This is a preliminary patch to enable wlan flowtable offload for EN7581
|
|
SoC.
