* leds: pwm: Disable PWM when going to suspendUwe Kleine-König2024-05-021-1/+7
| | | | | | | | | | | | On stm32mp1xx based machines (and others) a PWM consumer has to disable the PWM because an enabled PWM refuses to suspend. So check the LED_SUSPENDED flag and depending on that set the .enabled property.

* leds: trigger: pattern: Add support for hrtimerMartin Kurbanov2024-05-021-23/+103
| | | | | | | | | | | | | | | | | | | | | | Currently, led pattern trigger uses timer_list to schedule brightness changing. As we know from timer_list API [1], it's not accurate to milliseconds and depends on HZ granularity. Example: "0 10 0 0 50 10 50 0 100 10 100 0 150 10 150 0 200 10 200 0 250 10 250 0", we expect it to be 60ms long, but it can actually be up to ~120ms (add ~10ms for each pattern when HZ == 100). But sometimes, userspace needs time accurate led patterns to make sure that pattern will be executed during expected time slot. To achieve this goal the patch introduces optional hrtimer usage for led trigger pattern, because hrtimer is microseconds accurate timer.

* leds: mt6360: Fix the second LED can not enable torch mode by V4L2ChiaEn Wu2024-04-121-1/+11
| | | | | | | | | | | | | | | V4L2 will disable strobe mode of the LED device when enable torch mode, but this logic will conflict with the "priv->fled_torch_used" in "mt6360_strobe_set()". So after enabling torch mode of the first LED, the second LED will not be able to enable torch mode correctly. Therefore, at the beginning of "mt6360_strobe_set()", check whether the state of the upcoming change and the current LED device state are the same, so as to avoid the above problem.

In addition disable building the old audio mute LED trigger.

* | leds: trigger: Store brightness set by led_trigger_event()Heiner Kallweit2024-03-281-2/+4
|/ | | | | | | | | | | | | | | If a simple trigger is assigned to a LED, then the LED may be off until the next led_trigger_event() call. This may be an issue for simple triggers with rare led_trigger_event() calls, e.g. power supply charging indicators (drivers/power/supply/power_supply_leds.c). Therefore persist the brightness value of the last led_trigger_event() call and use this value if the trigger is assigned to a LED. In addition add a getter for the trigger brightness value.

This changed the logic where, in the previous implementation the dev from the trigger event was used to check if the carrier was ok, but in the new implementation with the generic function, the dev in trigger_data is used instead. This is problematic and cause a possible kernel panic due to the fact that the dev in the trigger_data still reference the old one as the new one (passed from the trigger event) still has to be hold and saved in the trigger_data struct (done in the NETDEV_REGISTER case). On calling of get_device_state(), an invalid net_dev is used and this cause a kernel panic. To handle this correctly, move the call to get_device_state() after the new net_dev is correctly set in trigger_data (in the NETDEV_REGISTER case) and correctly parse the new dev.

To clear and address this problem, change the logic where these additional trigger modes are listed. Since the netdev trigger REQUIRE a device name to be set, attach to the device name change function additional logic to parse the supported link speed modes using ethtool APIs and show only the supported link speed modes attribute. Link speed attribute are refreshed on device_name set and on NETDEV_CHANGE events. This only apply to the link speed modes and every other mode is still provided by default.
