Hi,

Nie. Slovak.

OK

I have not tried to do that. But considering it's custom chip from Qualcomm
then it's unlikely.

This is for RGB LEDs in phones that are connected via pmic.

> Is this for phone, btw? If so, which one?

Yes it is. And it's for many many phones actually. I have done this mainly
for SONY phones (Xperia 10, 10 Plus, XA2, XA2 Plus, XA2 Ultra).
All of them use these drivers for generating the PWM and controlling the
LEDs.

Best Regards,
Martin
