ARM: rpc: use legacy_timer_tick

2020-10-30T20:57:05+00:00

rpc is the only user of the timer_tick() function now, and can
just call the newly added generic version instead.

ARM/time: Remove read_boot_clock64()

2018-07-19T22:02:41+00:00

read_boot_clock64() is deleted, and replaced with
read_persistent_wall_and_boot_offset().

The default implementation of read_persistent_wall_and_boot_offset()
provides a better fallback than the current stubs for read_boot_clock64()
that arm has with no users, so remove the old code.

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

2015-04-03T06:18:23+00:00

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: 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: remove struct sys_timer suspend and resume fields

2012-12-24T16:36:37+00:00

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

2012-12-24T16:36:35+00:00

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.

ARM: 7413/1: move read_{boot,persistent}_clock to the architecture level

2012-05-06T10:09:21+00:00

At the moment, read_persistent_clock is implemented at the
platform level, which makes it impossible to compile these
platforms in a single kernel.

Implement these two functions at the architecture level, and
provide a thin registration interface for both read_boot_clock
and read_persistent_clock. The two affected platforms (OMAP and
Tegra) are converted at the same time.
