Merge tag 'leds-next-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/leds

Pull LED updates from Lee Jones:
"Core Frameworks:
- Ensure seldom updated triggers have a brightness value before first
update

New Device Support:
- Add support for Simatic IPC Device BX_59A to IPC LEDs Core
- Add support for Qualcomm PMI8950 PWM to LPG Core

New Functionality:
- Add a bunch of new LED function identifiers
- Add support for High Resolution Timers in LED Trigger Patten

Fix-ups:
- Shift out Audio Trigger to the Sound subsystem
- Convert suitable calls to devm_* managed resources
- Device Tree binding adaptions/conversions/creation
- Remove superfluous code/variables/attributes and simplify overall
- Use/convert to new/better APIs/helpers/MACROs instead of
hand-rolling implementations

Bug Fixes:
- Repair enabling Torch Mode from V4L2 on the second LED
- Ensure PWM is disabled when suspending"

+Date:		April 2024
+Description:
+		Specify a software pattern for the LED, that supports altering
+		the brightness for the specified duration with one software
+		timer. It can do gradual dimming and step change of brightness.
+
+		Unlike the /sys/class/leds/<led>/pattern, this attribute runs
+		a pattern on high-resolution timer (hrtimer).

-LEDs connected to pca9632, pca9633 or pca9634
-
-Required properties:
-- compatible : should be : "nxp,pca9632", "nxp,pca9633", "nxp,pca9634" or "nxp,pca9635"
-
-Optional properties:
-- nxp,totem-pole : use totem pole (push-pull) instead of open-drain (pca9632 defaults
-  to open-drain, newer chips to totem pole)
-- nxp,hw-blink : use hardware blinking instead of software blinking
-- nxp,period-scale : In some configurations, the chip blinks faster than expected.
-		     This parameter provides a scaling ratio (fixed point, decimal divided
-		     by 1000) to compensate, e.g. 1300=1.3x and 750=0.75x.
-- nxp,inverted-out: invert the polarity of the generated PWM

-Each led is represented as a sub-node of the nxp,pca963x device.
-
-LED sub-node properties:
-- label : (optional) see Documentation/devicetree/bindings/leds/common.txt
-- reg : number of LED line (could be from 0 to 3 in pca9632 or pca9633,
