From: Stephen Warren <[email protected]>
The overall aim of this series is to allow ARM (or indeed any) timer
drivers to be moved into drivers/clocksource without requiring a
struct or function prototype for each individual driver in include/linux.
The intent is eventually to create a single e.g. 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
This requires some rework prior to implementing of_clocksource_init():
ARM uses struct sys_timer to represent the individual machine's timer
driver. Many of the patches in this series are ARM-specific changes to
get rid of this struct, leaving just a single init function instead.
One function pointer in the struct provides the implementation of
arch_gettimeoffset(). Removing the struct and moving drivers into the
generic drivers/clocksource directory requires an arch-agnostic way of
registering the implementation of this function. The first few patches
in the series provide that, and rework various architectures to make use
of this facility rather than implementing the same thing themselves.
It would probably be easiest to merge this whole series through the
arm-soc tree. Anything else would require some co-ordination.

From: Stephen Warren <[email protected]>
Currently, whenever CONFIG_ARCH_USES_GETTIMEOFFSET is enabled, each
arch core provides a single implementation of arch_gettimeoffset(). In
many cases, different sub-architectures, different machines, or
different timer providers exist, and so the arch ends up implementing
arch_gettimeoffset() as a call-through-pointer anyway. Examples are
ARM, Cris, M68K, and it's arguable that the remaining architectures,
M32R and Blackfin, should be doing this anyway.
Modify arch_gettimeoffset so that it itself is a function pointer, which
the arch initializes. This will allow later changes to move the
initialization of this function into individual machine support or timer
drivers. This is particularly useful for code in drivers/clocksource
which should rely on an arch-independant mechanism to register their
implementation of arch_gettimeoffset().
This patch also converts the Cris architecture to set arch_gettimeoffset
directly to the final implementation in time_init(), because Cris already
had separate time_init() functions per sub-architecture. M68K and ARM
are converted to set arch_gettimeoffset the final implementation in later
patches, because they already have function pointers in place for this
purpose.

From: Stephen Warren <[email protected]>
remove m68k's mach_gettimeoffset function pointer, and instead directly
set the arch_gettimeoffset function pointer. This requires multiplying
all function results by 1000, since the removed m68k_gettimeoffset() did
this. Also, s/unsigned long/u32/ just to make the function prototypes
exactly match that of arch_gettimeoffset.

1.7.0.4
From: Stephen Warren <[email protected]>
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
RFC: This will be quite a large patch since it'll end up touching tens
or hundreds of ARM board files, timer drivers, etc. Perhaps it'd be
better to create patches that:
1) Add .init_time field to machine descriptor, update ARM's time_init to
use that if present, else fall back to .timer.init.
2) 1 patch per ARM sub-architecture to convert to from .timer to
.init_time.
3) Remove sys_timer and machine descriptor .timer field.
For now, this patch only converts Tegra as an example of my intent.

From: Stephen Warren <[email protected]>
These fields duplicate e.g. struct clock_event_device's suspend and
resume fields, so remove them now that nothing is using them. The aim
is to remove all fields from struct sys_timer except .init, then replace
the ARM machine descriptor's .timer field with a .init_time function
instead, and delete struct sys_timer.

Instead of using struct sys_timer's resume function, register syscore_ops
directly in s3c2410_timer_init(). This will allow the sys_timer suspend/
resume fields to be removed, and eventually lead to a complete removal of
struct sys_timer.

Oops. This one patch is a duplicate of 11/11 in the series I just sent.
Sorry.
From: Stephen Warren <[email protected]>
remove ARM's struct sys_timer .offset function pointer, and instead
directly set the arch_gettimeoffset function pointer when the timer
driver is initialized. This requires multiplying all function results
by 1000, since the removed arm_gettimeoffset() did this. Also,
s/unsigned long/u32/ just to make the function prototypes exactly
match that of arch_gettimeoffset.

1.7.0.4
From: Stephen Warren <[email protected]>
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
RFC: This will be quite a large patch since it'll end up touching tens
or hundreds of ARM board files, timer drivers, etc. Perhaps it'd be
better to create patches that:
1) Add .init_time field to machine descriptor, update ARM's time_init to
use that if present, else fall back to .timer.init.
2) 1 patch per ARM sub-architecture to convert to from .timer to
.init_time.
3) Remove sys_timer and machine descriptor .timer field.
For now, this patch only converts Tegra as an example of my intent.

Move usec to nsec conversion from arch_gettimeoffset() to
do_slow_gettimeoffset(); in a future patch, do_slow_gettimeoffset()
will be used directly as the implementation of arch_gettimeoffset(),
so needs to perform all required calculations.

This comment is now incorrect, it should say:
/* Calculate (1000000000 / 983040) * offset */
or perhaps to better explain what is being done:

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:

v2: Converted all platforms, not just Tegra.
This is based on next-20121107, so would need to be rebased to actually
apply. Arnd, Olof, what do you think the best plan for merging this into
arm-soc would be?
The patch is very large, so I've trimmed it for the mailing list, leaving
only the core ARM changes, changes outside arch/arm, and a couple platforms
which had slightly less routine changes. The full series can be found at:
git://nv-tegra.nvidia.com/user/swarren/linux-2.6 arm_timer_rework
It'd be great if maintainers could test this on their boards to make sure
I didn't make any silly mistakes, although there are far too many to Cc.

Thanks. I expanded on that slightly and went for:
/*
* Timer 4 is based on a 983.04 kHz reference clock,
* so dividing by 983040 gives the fraction of a second,
* so dividing by 0.983040 converts to uS.

Minor nit-pick here, but get_arch_timeoffset() or get_arch_tickoffset()
might be clearer, as gettimeoffset() sounds a little generic, and could
be confused with the higher-level timekeeping_inject_offset() call.
Otherwise this looks ok to me (disclaimer: I'm back from a 4 week leave,
so I may not have my brain plugged in all the way yet).
