The decision to move this over to drivers/ram is only about 6 weeks old.
However, I didn’t want to add a new driver in the old location (as we’d then
have to move it in the near future ; note that for the RK3399, I’ll submit a
patch to move the driver to drivers/ram for the next release cycle).
The patch has not been applied, as there’s unaddressed review comments:
I had requested that the amount of data structures are deduplicated, as the
pctl-register seemed the same as the rk3288 and the rk3368.
I think there was a bit more code that could be shared already.
We really need to get our DRAM drivers into shape, as these are becoming
a major source of code duplication.
