[PATCH 1/3] arm: omap: clocks: move CM_REG and PRM_REG macros

[PATCH 1/3] arm: omap: clocks: move CM_REG and PRM_REG macros

[Jan Luebbe]

These macros will be used by AM33xx as well, so move them to clocks.h.

Based on a patch by Teresa Gámez <t.gamez@phytec.de>.

Re: [PATCH 2/3] arm: omap: timers: split omap3/4 timer into a separate header

[Teresa Gamez]

Hello Jan,

I tried to apply this one on master for testing.
But it got rejected.  
Can you check it?

Regards,
Teresa

Defines without namespace become very painful sooner or later. You won't
be able to compile multiple versions of the timer. There is a high risk
that they conflict with other defines.

Please move these defines into the C file using it. They are used in a
single file only.
