MIPS: Always register R4K clock when selected

2013-10-29T20:25:26+00:00

Always register the R4K clocksource when CONFIG_CSRC_R4K is selected,
regardless of selected support for other clocksources. The kernel will
select the best clocksource based on their ratings, making it safe to
register R4K unconditionally and use it as a fallback should the
kernel be run on a system where other selected clocksources are
inoperable.

MIPS: Whitespace cleanup.

2013-02-01T09:00:22+00:00

Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.

MIPS: Remove usage of CEVT_R4K_LIB config option.

2012-12-13T17:15:24+00:00

I introduced it as a fallback because early revisions of Alchemy hardware
we shipped had a non-functional 32kHz timer and had to rely on the r4k
timer instead.  Previously the r4k timer was initialized regardless, but
it's useless with the "wait" instruction.

So long story short:   I need either the on-chip 32kHz timer OR the r4k
timer if the 32kHz one is unusable, but not both, and r4k timer is useless
when au1k_idle is in use.

The current in-kernel Alchemy boards all work with the 32kHz timer, so I'm
not against removing R4K_LIB symbols.

mips: Use generic mult/shift factor calculation for clocks

2009-11-13T19:46:24+00:00

Replace the MIPS functions of mult/shift factor calculation for clock
events and clock sources with inline functions which call the generic
functions. The minimum guaranteed conversion range is set to 4 seconds
which corresponds to the current MIPS implementation.
