right on the clock controller.

From: Guido Günther <[email protected]>
This is needed to make DRAM frequency scaling via devfreq as used
on the Librem 5 and Librem 5 Devkit.
With the interconnect support enabled we now need imx devfreq on top
to make this work.

Still a line break here is needed.

Drop the leading 0 in address and size. I saw some DTS using it but it's
not the common format. All nodes don't lead with 0 so why partitions are
different?
Best regards,
Krzysztof
On Birch I can never reach 220 and hence the display would never
turn off. Tests suggest 120 to be a good threshold value for all Birch
devices.
