Although the DPAA 1 FMan operations are coherent, the device tree
node for the FMan does not indicate that, resulting in a needless
loss of performance. Adding the missing dma-coherent property.
Fixes: 1ffbecdd8321 ("arm64: dts: add DPAA FMan nodes")

Hi, Shawn,
will this fix for the device trees be picked up in the stable trees as well?
Do I need to do something about it?
Thanks
Madalin
PS: will this make it into v5.10 or v5.11?

When it's landed in Linus' tree, stable kernel will pick it up due to
the Fixes: tag there. So you do not need to do anything about it.

I'm sending it to arm-soc folks as a material for v5.10-rc. So if
everything goes well, it will get into v5.10.
