[U-Boot] [RFC 0/2] Add cdns-i2c driver as drop in for zynq-i2c

[Moritz Fischer]

Hi all,

I spent some time moving over the zynq-i2c.c to support dm.
While doing that I realized that renaming it to cdns-i2c might
make sense since it now could be used with other SoCs that also use the
the Cadence IP.

This is a first shot, but I'd like to get some early feedback ;-)

Cheers,

    Moritz

PS: I skipped touching the Zynq board files for now, since I wanted to make sure
I get the driver right first ;-)
