Hi Chen-Yu Tsai, The led node names need some changes. 'linux,default-trigger' value does not fit. From leds-gpio.yaml: patternProperties: # The first form is preferred, but fall back to just 'led' anywhere in the # node name to at least catch some child nodes. "(^led-[0-9a-f]$|led)": type: object Rename led nodenames to 'led-0' form Also include all mail lists found with: ./scripts/get_maintainer.pl --nogit-fallback --nogit devicetree@vger.kernel.org If you like change the rest of dts with leds as well...

In this particular case, I'd say it's probably time to reevaluate the rather out-of-date binding. The apparent intent of the "linux,default-trigger" property seems to be to describe any trigger supported by Linux, so either the binding wants to be kept in sync with all the triggers Linux actually supports, or perhaps it should just be redefined as a free-form string. FWIW I'd be slightly inclined towards the latter, since the schema validator can't know whether the given trigger actually corresponds to the correct thing for whatever the LED is physically labelled on the board/case, nor whether the version(s) of Linux that people intend to use actually support that trigger (since it doesn't have to be the version contemporary with the schema definition), so strict validation of this particular property seems to be of limited value.

It is possible for LED class drivers to register their private triggers, so generic bindings cannot use predefined set for validation. I think that Rob just blindly converted common.txt to yaml and I acked that but didn't envisage the implications for validation. All in all, even that list in common.txt didn't include all existing generic LED triggers.

I'd say free form is easier to manage. Being in the list of valid triggers doesn't mean the kernel actually has support for it enabled. > > > > > - diy-led { > > > > > + diy_led: diy-led { > > > > > label = "red:diy"; > > > > > gpios = <&gpio0 RK_PB5 GPIO_ACTIVE_HIGH>; > > > > > default-state = "off"; > > > > > linux,default-trigger = "mmc1"; > > > > > }; > > This label probably should be "mmc1:red:activity" or something like that. Is changing this after it has been in some kernel releases OK? Wouldn't it be considered a break of sysfs ABI? Also, is there some guideline on how to name the labels? For sunxi we've been doing "${vendor}:${color}:${function}" since forever. As far as I can tell, the hardware vendor [1] has no specific uses for these two (red and yellow) LEDs designed in. And their GPIO lines are simply labeled "DIY" (for the red one) and "YELLOW". So I'm not sure if putting "our" interpretations and the default-trigger into the label is wise. For reference, the green one has its GPIO line labeled "WORK", and their intention from [1] is to have it as some sort of power / activity indicator. Hence it is named / labeled "work". As for the node names, I think we can keep it as is for now. It's not the preferred form, but there's really no need to change it either. And some overlay or script might actually expect that name.
