This is a splited patchset from https://patchwork.kernel.org/cover/11390589/
patch 11/14 and patch 12/14 posted 2 months ago.

This is to use cpufreq dt driver target_intermediate to implement
cpufreq for i.MX7ULP, because i.MX7ULP has some specific requirements
for core clk changing.

To make cpufreq on i.MX7ULP full function, there still more patches
required:
https://patchwork.kernel.org/cover/11491149/
https://patchwork.kernel.org/patch/11390559/

However with this current patchset applied, it not break anything,
because the cpufreq device has not been registered, and opp table
not added.

Peng Fan (2):
  cpufreq: Add i.MX7ULP to cpufreq-dt-platdev blacklist
  cpufreq: imx-cpufreq-dt: support i.MX7ULP
