Support for hidden LED ?

[rogerclarkmelbourne]

There appears to be a hidden LED on the Moto G4 play, which can be controlled by a Motorola app designed for the Moto X.

I've tried searching this codebase, but I can't find any mention of this LED.

Can anyone tell me hidden LED support is included in this repo ?

Could you tell me where the LED is on the device? There is an LED on the bottom, but, like all other hidden LEDs we've seen on the Moto G devices, it only functions when charging.

Thanks.

I mean the LED at the bottom, which I think is sometimes referred to as the "Charging LED".
(I need to double check if there are 2 LEDs next to each other as this has been reported on some phones)

On the Moto G 4 Play, this LED does not seem to get used at all by the stock version of Android.

I've searched this repo but I can't find any references to the LED class names that I think the phone uses e.g.

/sys/class/leds/charging

Am I looking in the right place, or is this part of the hardware layer handled in another repo ?
