Hi,
first of all I would rephrase subject a little bit.
Something like: "ARM: zynq: Add missing i2c get_rate for fixing i2c SPL"

The commit 'f48ef0d81aa837a33020f8d61abb3929ba613774' did break I2C support because requesting the clock for the I2C ip-block isn't supported during SPL.
To fixup this we add support requesting clocks for:
- i2c0
- i2c1

please remove this empty line.

I am also curious why you are enabling I2C in SPL. What are you doing with that?
Thanks, Michal
