Beginners • How to get the list of options for act_led_trigger ?

Hi,

I'm in the final stage of compiling my Linux kernel for my raspberry pi 4 Image may be NSFW.
Clik here to view.
(btw thanks for those how already helped me ! )

I'm reading the arch/arm64/boot/dts/overlays/README that describe how to use the Device Tree overlays

I can see the act_led_trigger and we can read

Choose which activity the LED tracks.
Use "heartbeat" for a nice load indicator.
(default "mmc")

but, is there other options ? or is it only ["heartbeat", "mmc"] ?

and how should it be encoded ?
act_led_trigger=mmc
or
act_led_trigger="mmc"

And finally whats does the heartbeat just a constant flashing ?

Thanks.
