Investigated this a bit further and the problem seems to be in the
power domain driver.

The change below fixes the problem on mx6:

diff --git a/drivers/base/power/domain.c b/drivers/base/power/domain.c
index e023066..461d03c 100644
--- a/drivers/base/power/domain.c

        for (i = 0; i < data->num_domains; i++) {
                if (!data->domains[i])
                        continue;
-               if (!pm_genpd_present(data->domains[i]))
-                       goto error;

                data->domains[i]->provider = &np->fwnode;
                data->domains[i]->has_provider = true;

, will submit this to the power domain folks.
