2009-04-21clocksource: pass clocksource to read() callbackMagnus Damm
Pass clocksource pointer to the read() callback for clocksources. This allows us to share the callback between multiple instances.

2009-01-11MIPS: make cp0 counter clocksource/event usable as fallback.Manuel Lauss
The current mips clock build infrastructure lets a system only use either the MIPS cp0 counter or a SoC specific timer as a clocksource / clockevent device. This patch renames the core cp0 counter clocksource / clockevent functions from mips_* to r4k_* and updates the wrappers in asm-mips/time.h to call these renamed functions instead. Chips which can detect whether it is safe to use a chip-specific timer can now fall back on the cp0 counter if necessary and possible (e.g. Alchemy with a follow-on patch). Existing behaviour is not changed in any way. Signed-off-by: Manuel Lauss <mano@roarinelk.homelinux.net> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-11-26[MIPS] Only build r4k clocksource for systems that work ok with it.Ralf Baechle
In particular as-is it's not suited for multicore and mutiprocessors systems where there is on guarantee that the counter are synchronized or running from the same clock at all. This broke Sibyte and probably others since the "[MIPS] Handle R4000/R4400 mfc0 from count register." commit. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
