clocksource/drivers/ti-32K: Fix misuse of "/**" comment

2024-01-22T12:16:32+00:00

Change "/**" to a common "/*" comment in a non-kernel-doc comment to avoid a kernel-doc warning: timer-ti-32k.c:42: warning: expecting prototype for timer(). Prototype was for OMAP2_32KSYNCNT_REV_OFF() instead Signed-off-by: Randy Dunlap Cc: Daniel Lezcano Cc: Thomas Gleixner Signed-off-by: Daniel Lezcano Link: https://lore.kernel.org/r/20240120173624.16769-1-rdunlap@infradead.org

clocksource/drivers: Replace HTTP links with HTTPS ones

2020-07-23T14:57:43+00:00

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

clocksource/drivers/timer-ti-32k: Add support for initializing directly

2020-05-22T22:01:04+00:00

Let's allow probing the 32k counter directly based on devicetree data to prepare for dropping the related legacy platform code. Let's only do this if the parent node is compatible with ti-sysc to make sure we have the related devicetree data available. Let's also show the 32k counter information before registering the clocksource, now we see it after the clocksource information which is a bit confusing.

clocksource/drivers/ti-32k: Add CLOCK_SOURCE_SUSPEND_NONSTOP flag for non-am43 SoCs

2018-09-13T13:23:35+00:00

The 32k clocksource is NONSTOP for non-am43 SoCs. Hence add the flag for all the other SoCs. Reported-by: Tony Lindgren Signed-off-by: Keerthy Acked-by: Tony Lindgren Signed-off-by: Daniel Lezcano

clocksource: ti-32k: Remove CLOCK_SOURCE_SUSPEND_NONSTOP flag

2018-08-02T11:35:08+00:00

Since commit 39232ed5a179 ("time: Introduce one suspend clocksource to compensate the suspend time") suspend/resume fails on AM437x platforms as the clocksource actually stops in suspend. Hence remove the CLOCK_SOURCE_SUSPEND_NONSTOP flag.

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: Use a plain u64 instead of cycle_t

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 Cc: Peter Zijlstra Cc: John Stultz

clocksource/drivers/ti-32k: Prevent ftrace recursion

2016-09-22T14:49:19+00:00

Currently ti-32k can be used as a scheduler clock. We properly marked omap_32k_read_sched_clock() as notrace but we then call another function ti_32k_read_cycles() that _wasn't_ notrace. Having a traceable function in the sched_clock() path leads to a recursion within ftrace and a kernel crash. Fix this by adding notrace attribute to the ti_32k_read_cycles() function.
