2016-12-25clocksource: Use a plain u64 instead of cycle_tThomas Gleixner
There is no point in having an extra type for extra confusion. u64 is unambiguous. Conversion was done with the following coccinelle script: @rem@ @@ -typedef u64 cycle_t; @fix@ typedef cycle_t; @@ -cycle_t +u64 Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Peter Zijlstra <peterz@infradead.org> Cc: John Stultz <john.stultz@linaro.org>
2016-06-28clocksource/drivers/mxs: Remove useless header <asm/mach/time.h>Daniel Lezcano
The driver includes the <asm/mach/time.h> header but it is pointless. Remove it. Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>
2016-06-28clocksources: Switch back to the clksrc tableDaniel Lezcano
All the clocksource drivers's init function are now converted to return an error code. CLOCKSOURCE_OF_DECLARE is no longer used as well as the clksrc-of table. Let's convert back the names: - CLOCKSOURCE_OF_DECLARE_RET => CLOCKSOURCE_OF_DECLARE - clksrc-of-ret => clksrc-of Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> For exynos_mct and samsung_pwm_timer: Acked-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> For arch/arc: Acked-by: Vineet Gupta <vgupta@synopsys.com> For mediatek driver: Acked-by: Matthias Brugger <matthias.bgg@gmail.com> For the Rockchip-part Acked-by: Heiko Stuebner <heiko@sntech.de> For STi : Acked-by: Patrice Chotard <patrice.chotard@st.com> For the mps2-timer.c and versatile.c changes: Acked-by: Liviu Dudau <Liviu.Dudau@arm.com> For the OXNAS part : Acked-by: Neil Armstrong <narmstrong@baylibre.com> For LPC32xx driver: Acked-by: Sylvain Lemieux <slemieux.tyco@gmail.com> For Broadcom Kona timer change: Acked-by: Ray Jui <ray.jui@broadcom.com> For Sun4i and Sun5i: Acked-by: Chen-Yu Tsai <wens@csie.org> For Meson6: Acked-by: Carlo Caione <carlo@caione.org> For Keystone: Acked-by: Santosh Shilimkar <ssantosh@kernel.org> For NPS: Acked-by: Noam Camus <noamca@mellanox.com> For bcm2835: Acked-by: Eric Anholt <eric@anholt.net>
2016-06-28clocksource/drivers/mxs: Convert init function to return errorDaniel Lezcano
The init function does not return any error, it prints a message, returns and lets the caller unaware if the state of the system. Change that by converting the init functions to return an error conforming to the CLOCKSOURCE_OF_RET prototype. Proper error handling (rollback, errno value) will be changed later case by case, thus this change just return back an error or success in the init function.

2015-08-10clockevents/drivers/mxs: Migrate to new 'set-state' interfaceViresh Kumar
Migrate mxs driver to the new 'set-state' interface provided by 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. Also drop: - 'mxs_clockevent_mode': as we have helpers available from core for the same. same state twice and so perhaps the check wasn't required. - 'clock_event_mode_label': CLOCK_EVT_MODE_* shouldn't be used anymore by drivers and it was used just to print old-state:new-state. The debug prints are called from mxs_irq_clear() now based on the state-name passed to it. The printed name will be same for shutdown and resume states as they use the same callback pointer.

2013-07-30clocksource: mxs_timer: Switch to sched_clock_register()Stephen Boyd
The 32 bit sched_clock interface now supports 64 bits. Upgrade to the 64 bit function to allow us to remove the 32 bit registration interface.

2013-06-12sched_clock: Make ARM's sched_clock generic for all architecturesStephen Boyd
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.
