ARM: SAMSUNG: Remove plat/regs-timer.h header (2013-06-25 01:13:49 +0900)

----------------------------------------------------------------
based on tags/samsung-cleanup-1

This cleanup of PWM Samsung is for:
1) moving remaining Samsung platforms to the new clocksource driver
2) removing old clocksource driver
3) adding new multiplatform- and DT-aware PWM driver
4) moving all Samsung platforms to use the new PWM driver
5) removing old PWM driver
6) removing all PWM-related code that is not used anymore

Hi Arnd and Olof

Please hold on pulling this one because Thierry Reding has objection on this. I think, this can be queued for next time.

Thanks,

If it's really just my objection keeping this back, then I'm fine with adding the comment in a follow-up patch.

No, we're also out of time for 3.11. But let's get this queued for 3.12 as soon as the merge window closes -- it's a very nice cleanup.

-Olof

Agreed.

Let me send pull-request regarding this to arm-soc after 3.11-rc1.

Thanks,
