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.

treewide/trivial: Remove ';;$' typo noise

2018-02-22T09:59:33+00:00

On lkml suggestions were made to split up such trivial typo fixes into per subsystem
patches:

  --- a/arch/x86/boot/compressed/eboot.c
  +++ b/arch/x86/boot/compressed/eboot.c
  @@ -439,7 +439,7 @@ setup_uga32(void **uga_handle, unsigned long size, u32 *width, u32 *height)

This patch is the result of the following script:

  $ sed -i 's/;;$/;/g' $(git grep -E ';;$'  | grep "\.[ch]:"  | grep -vwE 'for|ia64' | cut -d: -f1 | sort | uniq)

... followed by manual review to make sure it's all good.

Splitting this up is just crazy talk, let's get over with this and just do it.

clocksource/drivers: Rename clocksource_probe to timer_probe

2017-06-14T09:59:16+00:00

The function name is now renamed to 'timer_probe' for consistency with
the CLOCKSOURCE_OF_DECLARE => TIMER_OF_DECLARE change.

clocksource: cosmetic: Drop OF 'dependency' from symbols

2015-10-01T00:18:39+00:00

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

2015-04-03T06:18:23+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: call of_clk_init from default time_init handler

2013-09-29T19:09:15+00:00

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.

sched_clock: Make ARM's sched_clock generic for all architectures

2013-06-12T21:02:13+00:00

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

2013-04-11T20:11:14+00:00

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

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