That sucks.

1) The prefix is crap. It suggests this is about the generic clocksource code


Is the proper prefix

2) Sentences start with upper case letters

3) What exactly are 'marcos' ?

So a useful subject line would be;

clocksource/drivers/arm_arch_timer: Move enums and defines to header file

What does it sort out? Nothing, AFAICT.

You miss to explain WHY you are doing this. The list below is completely
useless because one can see that from the patch.

So this wants to be something like this:

To support the arm_arch_timer via ACPI we need to share defines and enums
between the driver and the ACPI parser code.

Split out the relevant defines and enums into arm_arch_timer.h. No functional

So this does 3 things at once.

1) Move existing defines and enums

2) Add a new enum and convert the driver to use it

3) Add new defines without using them

So this needs to be seperate

#1) This patch

#2) Seperate patch which adds the new enum and converts the places in the

#3) This needs to go into the patch which actually uses the defines.
