Quoting Enric Balletbo i Serra (2018-05-14 14:16:07)

From: Derek Basehore <redacted>

This adds the flag to the clk-ddr in rockchip to not use the cached
rate for get_rate. This is to handle timeout error conditions in SMC
for the set rate function.

We need some more information here. Why does timeout error condition in
set_rate() matter for get_rate()?
