DT nodes contain clock numbers which are referred by drivers
to get the clocks. These numbers are replaced by MACROs
which are defined in the exynos5420-clk.h header file.

This is a good idea, but we already have such conversion scheduled for
all the existing clock drivers in an automated way. Andrzej Hajda (on CC)
has a script that automatically converts DTS files and clock drivers from
enums to defines.

Also such change needs to be done in a timely manner, due to greatly
increasing chance of conflicting other patches.

My suggestion is to drop this and patch 3/3 from this series and let us
handle this using Andrzej's script at appropriate point of time.

By the way, this header is added in patch 3/3, so this patch breaks
bisectability, which is not acceptable.

Best regards,
Tomasz

Looks fine to me. I will drop them. But we have a requirement to keep 5420
up to date in mainline tree. I am hoping you will do it soon for all SoCs. In
case its delaying too much, I will request you to consider these again :).

Regards,
Rahul Sharma.
