clocksource/drivers/em_sti: Remove unneeded memset()s

2015-10-15T15:41:59+00:00

Memory for cs and ced fields in struct em_sti_priv is allocated by devm_kzalloc() in the beginning of em_sti_probe() so they don't need to be zeroed one more time in em_sti_register_clocksource() and in em_sti_register_clockevent(). Signed-off-by: Alexey Klimov Signed-off-by: Daniel Lezcano

clockevents/drivers/em_sti: Migrate to new 'set-state' interface

2015-08-06T10:16:42+00:00

Migrate em_sti driver to the new 'set-state' interface provided by the clockevents core, the earlier 'set-mode' interface is marked obsolete now. This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED. NOTE: This also drops a special check: if (old_mode == CLOCK_EVT_MODE_ONESHOT) em_sti_stop(p, USER_CLOCKEVENT); as it doesn't look like that important. This driver only supports ONESHOT and we can only move only to SHUTDOWN from ONESHOT and. Also on second call (on shutdown), em_sti_stop() would return without disabling the device again.

clocksource: Rename __clocksource_updatefreq_() to __clocksource_update_freq_()

2015-03-13T07:07:08+00:00

Ingo requested this function be renamed to improve readability, so I've renamed __clocksource_updatefreq_scale() as well as the __clocksource_updatefreq_hz/khz() functions to avoid squishedtogethernames. This touches some of the sh clocksources, which I've not tested. The arch/arm/plat-omap change is just a comment change for consistency.

clocksource: em_sti: Remove unnecessary OOM messages

2014-05-23T07:23:10+00:00

The site-specific OOM messages are unnecessary, because they duplicate the MM subsystem generic OOM message. Signed-off-by: Jingoo Han Signed-off-by: Daniel Lezcano

clocksource: em_sti: convert to clk_prepare/unprepare

Add calls to clk_prepare and unprepare so that EMMA Mobile EV2 can migrate to the common clock framework. Signed-off-by: Shinya Kuribayashi Acked-by: Daniel Lezcano Acked-by: Laurent Pinchart Acked-by: Magnus Damm Signed-off-by: Simon Horman Signed-off-by: Daniel Lezcano

clocksource: em_sti: Set cpu_possible_mask to fix SMP broadcast

2013-09-26T00:31:04+00:00

Update the STI driver by setting cpu_possible_mask to make EMEV2 SMP work as expected together with the ARM broadcast timer. This breakage was introduced by: f7db706 ARM: 7674/1: smp: Avoid dummy clockevent being preferred over real hardware clock-event Without this fix SMP operation is broken on EMEV2 since no broadcast timer interrupts trigger on the secondary CPU cores.

clocksource: em_sti: Set initcall level to subsys

2013-03-12T17:24:36+00:00

The reason for this is to ensure that STI is probed earlier than with its previous initcall level, module init. This came up as a problem with using CMT as a clock source kzm9g-reference which does not make use of early timers or devices. In that scenario initialisation of SDHI and MMCIF both stall on msleep() calls due to the absence of a initialised clock source. The purpose of this change is to keep the STI code in sync with the CMT code which has been modified in a similar manner.. Boot tested on: kzm9d. Signed-off-by: Simon Horman

Drivers: clocksource: remove __dev* attributes.

2013-01-03T23:57:15+00:00

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
