* MIPS: clock.h: Remove declaration of cpu_wait.Ralf Baechle2013-05-221-2/+0
| | | | | | Duplicate and has no business in this header file. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* MIPS: Loongson 2: Sort out clock managment.Ralf Baechle2012-08-011-11/+0
| | | | | | | For unexplainable reasons the Loongson 2 clock API was implemented in a module so fixing this involved shifting large amounts of code around. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* MIPS: Loongson 2F: Add CPU frequency scaling supportWu Zhangjin2009-12-171-0/+64
Loongson 2F supports CPU clock scaling. When put it into wait mode by setting the frequency as ZERO it will stay in this mode until an external interrupt wakes the CPU again. To enable clock scaling support, an external timer of a known stable rate is required.
