I'm trying to use the out of tree driver from Altera's latest kernel,
from here:
https://github.com/altera-opensource/linux-socfpga/tree/socfpga-4.4

But it's not a totally different driver, it's just an older version of
this driver.  I'm thinking of porting in this version since I think it's
much improved (after V11 one would hope so).  Really, Altera should
update their supported kernel with this code.

Comments about what's on your branch.

Commit "ARM: socfpga: Add Candence QSPI controller DT node" only
adds the node for Cyclone 5.  This same DT node should also be added to
the socfpga_arria10.dtsi file.
