clocksource/drivers/digicolor: Convert to SPDX identifier

2022-05-18T09:08:59+00:00

The license information clearly states GPL version 2 only. The extra text which excludes warranties is an excerpt of the corresponding GPLv2 clause 11. So the SPDX identifier covers it completely.

clocksource/drivers: Rename CLOCKSOURCE_OF_DECLARE to TIMER_OF_DECLARE

2017-06-14T09:58:45+00:00

The CLOCKSOURCE_OF_DECLARE macro is used widely for the timers to declare the clocksource at early stage. However, this macro is also used to initialize the clockevent if any, or the clockevent only. It was originally suggested to declare another macro to initialize a clockevent, so in order to separate the two entities even they belong to the same IP. This was not accepted because of the impact on the DT where splitting a clocksource/clockevent definition does not make sense as it is a Linux concept not a hardware description. On the other side, the clocksource has not interrupt declared while the clockevent has, so it is easy from the driver to know if the description is for a clockevent or a clocksource, IOW it could be implemented at the driver level. So instead of dealing with a named clocksource macro, let's use a more generic one: TIMER_OF_DECLARE. The patch has not functional changes.

clocksource: Add missing line break to error messages

Printing with pr_* functions requires adding line break manually. Signed-off-by: Rafał Miłecki Acked-by: Thierry Reding Signed-off-by: Daniel Lezcano

sched/headers: Prepare for new header dependencies before moving code to

2017-03-02T07:42:27+00:00

We are going to split out of , which will have to be picked up from other headers and .c files. Create a trivial placeholder file that just maps to to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

clocksources: Switch back to the clksrc table

2016-06-28T08:19:35+00:00

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 For exynos_mct and samsung_pwm_timer: Acked-by: Krzysztof Kozlowski For arch/arc: Acked-by: Vineet Gupta For mediatek driver: Acked-by: Matthias Brugger For the Rockchip-part Acked-by: Heiko Stuebner For STi : Acked-by: Patrice Chotard For the mps2-timer.c and versatile.c changes: Acked-by: Liviu Dudau For the OXNAS part : Acked-by: Neil Armstrong For LPC32xx driver: Acked-by: Sylvain Lemieux For Broadcom Kona timer change: Acked-by: Ray Jui For Sun4i and Sun5i: Acked-by: Chen-Yu Tsai For Meson6: Acked-by: Carlo Caione For Keystone: Acked-by: Santosh Shilimkar For NPS: Acked-by: Noam Camus For bcm2835: Acked-by: Eric Anholt

clocksource/drivers/digicolor: Convert init function to return error

2016-06-28T08:19:20+00:00

The init functions do not return any error. They behave as the following: - panic, thus leading to a kernel crash while another timer may work and make the system boot up correctly or - print an error and let 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.

clocksource/drivers/digicolor: Fix warning of non-static function

2016-06-28T08:16:43+00:00

Change the dc_timer function to be static as it is not used outside this driver. This fixes the following warning: drivers/clocksource/timer-digicolor.c:66:24: warning: symbol 'dc_timer' was not declared. Should it be static?

clocksource/drivers/digicolor: Prevent ftrace recursion

2015-10-27T00:34:17+00:00

Having a traceable function in the sched_clock() path leads to a recursion within ftrace and a kernel crash. We should not trace digicolor_timer_sched_read() function. Fix this by adding the notrace attribute to this function. Signed-off-by: Jisheng Zhang Acked-by: Baruch Siach Signed-off-by: Daniel Lezcano

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

2015-08-10T09:40:45+00:00

Migrate digicolor 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.

clocksource: Driver for Conexant Digicolor SoC timer

2015-01-29T13:02:15+00:00

Add clocksource driver to the Conexant CX92755 SoC, part of the Digicolor SoCs series. Hardware provides 8 timers, A to H. Timer A is dedicated to a future watchdog driver so we don't use it here. Use timer B for sched_clock, and timer C for clock_event. Signed-off-by: Baruch Siach Signed-off-by: Daniel Lezcano
