Thx for the report Randy. I'm calling out Mellanox folks to see if they can
provide a fixup, else we will revert the corresponding change.

@Elad, upstream commit 3f9cd874dcc8705 "ARC: [plat-eznps] avoid toggling of DPC
register" added reference to struct nps_host_reg_aux_dpc but the definition is
missing. Can you please provide a fixup as I have no idea of that platform
specific struct.

@ Leon, reaching our to you, since it seems you removed Elad from MAINTAINERS
file, so I'm not sure if he is still at Mellanox.
The two folks I worked with on EZCHiip Linux port Noam Camus and Gilad have left
Mellanox.
If you or someone from Mellanox are interested in maintaining this platform,
please update the arch/arc/plat-eznps section of MAINTAINERS file.

Thx,
-Vineet
