However, this driver, even after applying your series, is still far
from a state that would allow it to be enabled. The most important
issue is direct access to CMU registers, based on static mapping,
which is not allowed on multiplatform kernels and
multiplatform-awareness for drivers is currently a must.
To allow this driver to be enabled, it needs to be converted to use
common clock framework functions to configure all clocks, e.g.
clk_set_rate(), clk_set_parent(), etc., without accessing CMU
registers directly.
Of course as long as the driver is effectively unusable, to keep
development, we can proceed with refactoring it step-by-step and
your series would be basically the first step, after addressing the
review comments.
I agree your opinion. When setting frequency of memory bus, this
driver access directly to CMU registers. I know it should be modified
by using common clk framework as your comment.
I'll send patch set about using common clk framework instead of CMU
register based on static mapping after finished the review and apply
of this patch set as next step.
Hi Chanwoo,
any news on this?
I would love to test this devfreq driver with the clk_set_floor_rate API
I'm adding to the common clk framework.

Tomeu
