Subject: [PATCH] ath79: ignore the abused interrupt-map on pcie node
|
||
|
|
|
||
|
|
ath79 PCIe interrupt controller has stopped working correctly. This
|
||
|
|
is because the DT exposing a non-sensical interrupt-map property,
|
||
|
|
and their drivers relying on the kernel ignoring this property[1].
|
||
|
|
|
||
|
|
This patch fix the pcie init error:
|
||
|
|
ath9k 0000:00:00.0: of_irq_parse_pci: failed with rc=-14
|
||
|
|
|
||
|
|
Notice:
|
||
|
|
This is just a workaround, not a fix. PCIe driver and related dts
|
||
|
|
node need to be rewritten.
