clocksource: cosmetic: Drop OF 'dependency' from symbols

2015-10-01T00:18:39Z

Seeing the 'of' characters in a symbol that is being called from ACPI seems to freak out people. So let's do a bit of pointless renaming so that these folks do feel at home.

ARM, clocksource/drivers: Provide read_boot_clock64() and read_persistent_clock64() and use them

2015-04-03T06:18:23Z

As part of addressing "y2038 problem" for in-kernel uses, this patch converts read_boot_clock() to read_boot_clock64() and read_persistent_clock() to read_persistent_clock64() using timespec64 by converting clock_access_fn to use timespec64.

ARM: call of_clk_init from default time_init handler

2013-09-29T19:09:15Z

Most DT ARM machs require common clock providers initialized before timers. Currently, arch/arm machs use .init_time to call of_clk_init right before clocksource_of_init. This prevents to remove that callback and use the default one instead. This patch adds a call to of_clk_init() to the default .init_time callback for COMMON_CLK enabled machs to allow to remove custom callbacks where applicable. While at it, also reorder includes alphabetically. Signed-off-by: Sebastian Hesselbarth

sched_clock: Make ARM's sched_clock generic for all architectures

2013-06-12T21:02:13Z

Nothing about the sched_clock implementation in the ARM port is specific to the architecture. Generalize the code so that other architectures can use it by selecting GENERIC_SCHED_CLOCK.

ARM: make machine_desc->init_time default to clocksource_of_init

2013-04-11T20:11:14Z

Originally from a default machine descriptor patch from Arnd, pull out just the default call to clocksource_of_init part. This is needed so that platforms can simply remove .init_time calls as they are converted to use clocksource_of_init.

ARM: delete struct sys_timer

2012-12-24T16:36:38Z

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: remove struct sys_timer suspend and resume fields

2012-12-24T16:36:37Z

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.

ARM: set arch_gettimeoffset directly

2012-12-24T16:36:35Z

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.

time: convert arch_gettimeoffset to a pointer

2012-12-24T16:36:07Z

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 to the final implementation in later patches, because they already have function pointers in place for this purpose.
