+Stratix10 SoCFPGA ECC Manager
+The Stratix10 SoC ECC Manager handles the IRQs for each peripheral
+in a shared register similar to the Arria10. However, ECC requires
+access to registers that can only be read in EL3 with SMC calls.
+Therefore the device tree is slightly different.
+
+Required Properties:
+- compatible : Should be "altr,socfpga-s10-ecc-manager"
Altera technically doesn't exist anymore, should this be
"intel,stratix10-ecc-manager"?
I was trying to be consistent with the older names but I agree with your
argument. I will change this. Thanks
After looking at the Stratix10 device tree, there are only "altr," in
there. For instance the top node is:
compatible = "altr,socfpga-stratix10";
and even the directory that the device tree is in is named "altera"
so I'll stick with the existing "altr," designation to be consistent.
Thanks,
Thor
