icc + imx-bus + imx8m-ddrc is an approach to have support for
dropping the bus and ddr clock rates when there is no user needing the
higher rates. This used to be done in our NXP tree via something called
busfreq. The problem with busfreq is that it cannot be upstreamed and
it's quite limited. As of now, there is no support for dropping bus and
ddr clock rates for any of the i.MX platforms in upstream. Parts of the
implementation of this new approach made it upstream a couple of
years ago. Therefore, even if you compile the interconnect driver in,
you won't have the full functionality. With this patchset we'll get
support for i.MX8MQ first. The rest of 8M platforms would get support
once we agree on i.MX8MQ since the generic part would not change at all.
I'll send a subsequent updated version soon, with all the comments taken
care of.
