ARM: delete struct sys_timer

2012-12-24T16:36:38+00:00

Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

ARM: u300: convert to sparse IRQs

2012-08-13T11:53:07+00:00

This converts the U300 to use sparse IRQs, which is simple now that the number of machines are reduced. Signed-off-by: Linus Walleij

ARM: u300: merge u300.c into core.c and rid headers

2012-08-13T11:53:06+00:00

This gets rid of the separate u300.c file in mach-u300 since it can just as well live right in core.c, then we also get rid of the broadcasted file that is not helping anyone. Put the interface to the system timer into a separate header. Signed-off-by: Linus Walleij

ARM: u300: convert to common clock

2012-07-11T22:36:45+00:00

This converts the U300 clock implementation over to use the common struct clk and moves the implementation down into drivers/clk. Since VCO isn't used in tree it was removed, it's not hard to put it back in if need be. Signed-off-by: Linus Walleij [mturquette@linaro.org: trivial Makefile conflict] Signed-off-by: Mike Turquette

ARM: 7205/2: sched_clock: allow sched_clock to be selected at runtime

2011-12-18T23:00:26+00:00

sched_clock() is yet another blocker on the road to the single image. This patch implements an idea by Russell King: http://www.spinics.net/lists/linux-omap/msg49561.html Instead of asking the platform to implement both sched_clock() itself and the rollover callback, simply register a read() function, and let the ARM code care about sched_clock() itself, the conversion to ns and the rollover. sched_clock() uses this read() function as an indirection to the platform code. If the platform doesn't provide a read(), the code falls back to the jiffy counter (just like the default sched_clock). This allow some simplifications and possibly some footprint gain when multiple platforms are compiled in. Among the drawbacks, the removal of the *_fixed_sched_clock optimization which could negatively impact some platforms (sa1100, tegra, versatile and omap). Tested on 11MPCore, OMAP4 and Tegra.

mach-u300: cleanup clockevent code

2011-06-23T10:09:42+00:00

Use the new clockevents_config_and_register() function to register the U300 clockevent, since that code requires ->cpumask to be set we set this even on this UP system to please the framework. Cc: Thomas Gleixner Signed-off-by: Linus Walleij

ARM: 6947/2: mach-u300: fix compilation error in timer

2011-06-06T09:56:10+00:00

The introduction of the mmio timer accidentally referenced the old clocksource struct which does not exist anymore. Fix this by using a simple string instead. Signed-off-by: Linus Walleij Signed-off-by: Russell King

clocksource: convert ARM 32-bit up counting clocksources

2011-05-23T17:04:51+00:00

Convert ixp4xx, lpc32xx, mxc, netx, pxa, sa1100, tcc8k, tegra and u300 to use the generic mmio clocksource recently introduced.

ARM: u300: convert sched_clock() to use new infrastructure

2010-12-22T22:44:47+00:00

Convert u300 to use the new sched_clock() infrastructure for extending 32bit counters to full 64-bit nanoseconds. Acked-by: Linus Walleij Signed-off-by: Russell King

ARM: ensure all sched_clock() implementations are notrace marked

2010-12-22T22:44:42+00:00

ftrace requires sched_clock() to be notrace. Ensure that all implementations are so marked. Also make sure that they include linux/sched.h Also ensure OMAP clocksource read functions are marked notrace as they're used for sched_clock() too.
