2010-05-21MIPS: Oprofile: Loongson: Unify macro for setting eventsWu Zhangjin
Unified macro for counter0 and counter1 to set the event in the control register. This will be needed by Perf. Signed-off-by: Wu Zhangjin <wuzhangjin@gmail.com> Cc: linux-mips@linux-mips.org Patchwork: http://patchwork.linux-mips.org/patch/1200/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2010-05-21MIPS: nofpu and nodsp only affect CPU0Kevin Cernekee
The "nofpu" and "nodsp" kernel command line options currently do not affect CPUs that are brought online later in the boot process or hotplugged at runtime. It is desirable to apply the nofpu/nodsp options to all CPUs in the system, so that surprising results are not seen when a process migrates from one CPU to another.

2010-05-20OMAP3 clock: remove unnecessary duplicate of dpll4_m2_ck, added for 36xxPaul Walmsley
Commit 678bc9a2eabb7f444ef8ad1cfc5ef394e2bd8bf2 split dpll4_m2_ck, creating a 34xx and a 36xx variant, to handle the additional 16 divider steps provided on the 36xx. This in turn required dynamic rewriting of the clock tree during initialization, which is undesirable. All this seems to be unnecessary, though, since the additional 16 divider steps can simply be marked with RATE_IN_36XX. This patch does so and re-merges the affected structures.

2010-05-20OMAP2+ clock: clean up clkt_clksel.cPaul Walmsley
This patch cleans up arch/arm/mach-omap2/clkt_clksel.c. It: - makes several functions static that are not called outside the file; - adds documentation; - makes some code paths easier to read (hopefully), by breaking up compound statements and removing redundant checks; - converts some pr_err()s that indicate clock tree data problems into WARN()s, so they are more likely to be noticed; - and moves omap2_clk_round_rate() back into mach-omap2/clock.c, its proper home, since it is not clksel-specific.

2010-05-20OMAP2+ clock: remove DEFAULT_RATE clksel_rate flagPaul Walmsley
The DEFAULT_RATE clksel_rate flag is essentially useless. It was set on some of the lowest divisors, which, when switching to a much higher-rate parent, could have potentially resulted in rates that exceeded the hardware specifications for downstream clocks in the window between the clk_set_parent(), and a subsequent clk_set_rate(). It seems much safer to just remove the flag and always use the highest available divisor (resulting in the lowest possible rate) after the switch, and this patch does so. Ideally, it would be best to first attempt to switch to a divisor that matches the clock's rate with the previous parent, if at all possible. But that is a project for some other day or some other person. The parent changing code is rarely used. Signed-off-by: Paul Walmsley <paul@pwsan.com>
2010-05-20OMAP3: PM: PM_MPUGRPSEL writes should use GRPSEL macros, not EN macrosPaul Walmsley
Writes to the PM_*GRPSEL registers should use _GRPSEL_ macros, not _EN_ macros, to match the TRM and guard against inadvertent error. This patch should not cause any functional change.

2010-05-20OMAP2+ PRCM: convert remaining PRCM macros to the _SHIFT/_MASK suffixesPaul Walmsley
Fix all of the remaining PRCM register shift/bitmask macros that did not use the _SHIFT/_MASK suffixes to use them. This makes the use of these macros consistent. It is intended to reduce error, as code can be inspected visually by reviewers to ensure that bitshifts and bitmasks are used in the appropriate places.
