[PATCH 6.1 372/440] MIPS: dts: loongson: Add ISA node

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jiaxun Yang <jiaxun.yang@xxxxxxxxxxx>

commit da3f62466e5afc752f8b72146bbc4700dbba5a9f upstream.

ISA node is required by Loongson64 platforms to initialize
PIO support.

Kernel will hang at boot without ISA node.
