clocksource: sh_cmt: Remove nested spinlock fix

2010-12-17T10:38:33+00:00

There are control flow that sh_cmt_set_next() does double
spin-lock. The callers sh_cmt_{start,stop}() already have
lock. But another callers sh_cmt_clock_event_{start,next}()
does not.

Now sh_cmt_set_next() does not lock by itself. All the
callers should hold spin-lock before calling it.

[damm@opensource.se: use __sh_cmt_set_next() to simplify code]
[damm@opensource.se: added stable, suitable for v2.6.35 + v2.6.36]

ARM: shmobile: remove sh_timer_config clk member

2010-10-31T14:40:39+00:00

Now when the SH-Mobile ARM platforms have been converted
to use device name it is possible to remove "clk" from
struct sh_timer_config.

clocksource: sh_cmt: Rate calculation fix

2010-08-04T07:01:29+00:00

Fix the rate calculation in the CMT driver.
Without this fix the clocksource runs way
too fast and we get a divide-by-zero error.

clocksource: sh_cmt: One-off clockevent fix V2

2010-08-04T07:01:24+00:00

Fix a one-off error in the CMT driver V2. The match register
should be programmed with the period minus one.

Many thanks to Eiraku-san for tracking down this issue.

x86: Convert common clocksources to use clocksource_register_hz/khz

2010-07-27T10:40:55+00:00

This converts the most common of the x86 clocksources over to use
clocksource_register_hz/khz.

clocksource: sh_cmt: Fix up bogus shift value.

2010-06-22T07:41:31+00:00

The previous CMT fixup accidentally copied in the TMU shift value, reset
this back to its original value while preserving the TMU fix.

clocksource: sh_cmt: compute mult and shift before registration

2010-06-02T08:10:44+00:00

Based on the sh_tmu change in 66f49121ffa41a19c59965b31b046d8368fec3c7
("clocksource: sh_tmu: compute mult and shift before registration").
The same issues impact the sh_cmt driver, so we take the same approach
here.

clocksource: sh_tmu: compute mult and shift before registration

2010-06-02T08:02:35+00:00

Since commit 98962465ed9e6ea99c38e0af63fe1dcb5a79dc25 ("nohz: Prevent
clocksource wrapping during idle"), the CPU of an R2D board never goes
to idle. This commit assumes that mult and shift are assigned before
the clocksource is registered. As a consequence the safe maximum sleep
time is negative and the CPU never goes into idle.

This patch fixes the problem by moving mult and shift initialization
from sh_tmu_clocksource_enable() to sh_tmu_register_clocksource().
